Shock Absorbers

Tough Dog shock absorbers are built to the highest levels of quality.

Our 41mm foam cell shock has been voted the number one shock as ‘best all-round performer’ by Australian 4WD Action magazine. If you are looking to make tracks, a set of Tough Dog shocks is exactly the place to start.

 


Nitrogen Gas Charged Shock Absorbers

Tough Dog Nitrogen Gas shock absorbers have been designed with control and comfort in mind.

Nitro gas shocks are built with multi stage velocity sensitive valving to ensure the shock is capable of performing at any speed. As the shock moves faster to absorb small bumps in the road like corrugations, the valving in the shock responds to maintain the ride control characteristics. These shocks are perfectly suited to light and medium four wheel drives and vehicles with leaf sprung suspension.

    • 35mm Internal bore and piston with twin tube design
    • Low pressure nitrogen gas to eliminate fade for better performance and comfortable ride

Description

41mm bore foam cell shock absorbers

Tough Dog’s award winning Foam Cell shock is our best selling shock for all round performance. Whether you head bush on the occasional weekend or for the majority of the year, Foam Cell shocks will handle your application.

The ‘Foam Cell’ that makes all the difference is a micro-cellular foam insert that helps to drastically reduce the effects of shock fade, allowing your shocks to perform better for longer, even on the harshest of corrugations. Cavitation and Aeration are the undoing of any shock absorber. As the shock is worked harder, the oil and gas in the outer chamber begins to mix and form bubbles, lowering the viscosity of the oil. When this aerated oil passes through the valve, there is reduced resistance, stopping the shock form performing correctly. The Foam Cell insert, with its trapped gas micro cells takes up the empty space in the shock normally taken up by air or nitrogen gas. This eliminates the possibility of bubbles forming, allowing the shock to get on with the job with an unparalleled resistance to shock fade.

40mm bore adjustable shock absorbers

The 40mm adjustable shock brings the ability to fine tune your ride control to just about every 4WD user. The shock offers 9 different stages of adjustment, to fine tune the ride characteristics to your personal preference and application.

In reality, very few vehicles serve only one purpose. Most 4WD’s today are the family car, off road toy, touring escape, towing rig or tradesman’s work platform all rolled into one. We demand so much of our vehicles, and every situation will need something just a little bit different. As well as being fully adjustable, these shocks are equipped with our Foam Cell technology, minimising aeration and cavitation to maximise the shocks ability to resist fade, and perform reliably in harsh and demanding conditions. Our adjustable shocks are built tough for the Aussie outback, and incorporate an ABS plastic dust shield as well as an external dust wiper seal to protect the shock’s internals from grit which can damage the oil seals around the chrome rod. When fully extended, the shock is at its most vulnerable to damage from side load. The internal bump stop and piston rod guide ensure the shock is supported at the extremes of its travel. These tough units are available for a wide range of applications.

    • 40mm internal bore
    • 60mm external casing
    • 18mm chrome-plated rod
    • High temperature, all weather oil
    • Foam cell
    • 9 Stage external adjustment

    • 2 year / 40,000km warranty (conditions apply) 

 


45mm big bore adjustable shock absorbers

These tough puppies are the largest bore externally adjustable shocks available on the market. There is nothing that can compare to the 45mm bore in a 70mm outer casing. This is one serious shock.

The 9 stages of adjustment mean you can control the firmness of your shocks easily, and adapt to the conditions as required. Choose a firmer ride for your highway travels, and then dial them down when it’s time to get down to business. 45mm big bore adjustables are designed for big lift applications up to six inches over factory in some vehicles. Our adjustable shocks are built tough for the Aussie outback. As well as the Foam Cell insert to combat shock fade, the 45mm adjustable also incorporate an ABS plastic dust shield as well as an external dust wiper seal to protect the shock’s internals from grit which can damage the oil seals around the chrome rod. When fully extended, the shock is at its most vulnerable to damage from side load. The internal bump stop and piston rod guide ensure the shock is supported at the extremes of its travel. Our big bore shocks also have a DU bushing fitted internally to protect the seals from damage caused by side load at full extension.

Steering Dampers

Quality steering components go a huge way to alleviating driver fatigue, Rough and unforgiving road surfaces can transfer through the wheels and up to the steering wheel.

If you’re constantly fighting to keep the vehicle on track, eventually that effort will take its toll. Tough Dog steering dampers are on your side when it comes to taming steering shimmy and shake.

 


EXT HEAVY DUTY STEERING DAMPER

The Tough Dog EXT steering damper is our affordable, heavy duty replacement damper.

Designed for mild applications as a replacement damper when the OEM gear just isn’t quite cutting the mustard, this damper will give you control and feeling back in your steering set up. With a 35mm internal bore and our Foam Cell insert to fight against fade in harsh use situations, this damper is the perfect companion for anyone looking to gain a new lease on life from their steering.

    • Superb road handling characteristics
    • 35mm bore for heavy-duty use
    • Eliminate shimmy
    • 2 Year/40,000km warranty (conditions apply)
    • Large range to suit most 4WD applications

 


RTC Steering Damper

Sir Isaac Newton might never have owned a 4WD, but he certainly knew what he was on about when he wrote his 3rd law of physics.

“For every action, there is an equal and opposite reaction.” Every time something fights your steering, the Return To Centre damper is right there with the equal and opposite reaction to keep you on track. Tough Dog steering stabilisers are the only award-winning RTC steering damper on the market. We paved the way for return to centre dampers in Australia. Our designs are customised for each application. Using the return to centre principle, the coil over spring forces the steering damper to return to the neutral position, helping to eliminate steering wheel kick on uneven surfaces. The return to centre damper aids drivers in their fight with the steering wheel over rough terrain, taming the erratic steering movement without compromising overall steering feel and response. Take the fight out of your steering today with an RTC damper.

    • Reduces shimmy and shake
    • Reduces fatigue on a long drive as the coil steers you straight.
    • Returns the steering wheel back to centre, especially when oversize tyres are fitted.
    • Available for manual and power steer vehicles
    • 2 Year/40,000km warranty (conditions apply)

 


XHD RTC steering damper

This damper is designed for those extreme use applications like vehicles with oversized tires and large suspension lifts. Taking the principle of the return to centre damper to the extreme, this damper certainly packs a punch when it comes to straightening out your steering.

When a vehicle is fitted with a suspension lift greater than 100mm, the geometry of the front arms, and the length of travel required from the damper will change, requiring a larger, longer heavier duty damper. Our XHD dampers come will with all the brackets required to mount the damper as well as instructions on correct configuration of the coil and collar arrangement. Some modification may be required to ensure correct fit. Suitable for vehicles with a suspension lift of 4” / 100mm or more. Available for 80/100 series LandCruisers, Nissan Patrol GQ/GU & Ford F250 models. Tough Dog also offer their pioneer ‘SV’ adjustable steering damper in larger sized to suit vehicles with more than 100mm of lift. View the ‘SV’ damper here.

    • Superb road handling characteristics
    • Return-to-centre principle especially for oversize tyres
    • Eliminate shimmy and assist in blowouts
    • Reduced driver fatigue on long distance driving
    • 1 Year/20,000km warranty (conditions apply)

 


SV Adjustable Steering Damper

Our award winning ‘SV’ adjustable damper is the only one of its kind to offer users the ability to adjust the damping force to suite driving style and vehicle requirements.

It is especially effective on vehicles with oversized wheels, or increased wheel track that experience steering shimmy. The damping force is adjusted until the wheel shake is ‘tuned’ out of the equation. Let’s face it, every vehicle is different, and even small factors like tyre wear can affect the overall performance of the steering. With the SV unit, those factors are no longer a problem because a change in steering feel is just a dial turn away. SV dampers are available for most vehicles up to 50mm suspension lift, and for some vehicles up to 150mm of lift.

    • Superb road handling characteristics
    • 35mm bore for heavy-duty use
    • Eliminate shimmy
    • 2 Year/40,000 km warranty
    • Large range to suit most 4WD applications
    • 2 Year/40,000km warranty for 0 – 100mm lift applications (conditions apply)
    • 1 Year/20,000km warranty 100mm+ lift applications (conditions apply)

 


Springs

Tough Dog springs are all designed in house, and manufactured from a range of quality materials.

Whether it’s comfort or load carrying you need, Tough Dog have a spring you can count on.

 

 


Coil Springs

Tough Dog coil springs are designed and manufactured in Australia to exacting standards to stand up to some of the harshest conditions found anywhere in the world.

Made from German X5K spring steel, our coils can be designed with less material while maintaining superior ride quality & load carrying characteristics. The spring retains its original memory even after heavy loading. The result? A lighter, tougher coil that can handle just about anything you can throw at it.

    • Shot peened to relieve stress
    • Scragged and load tested
    • Formed on precision mandrels
    • Hot formed to maintain spring memory
    • Powder-coated for looks and corrosion resistance
    • 3 year / 60,000km warranty (up to 2”/50mm lift)
    • E height up to 6” lift available

 


Leaf Springs

Designed in Australia, Tough Dog leaf springs offer a spring pack for just about any application you might require. Our springs are a proven performer in any situation.

Tough Dog leaf springs are a truly progressive rate leaf spring. Each leaf is set slightly higher than the leaf above so there is contact along the whole length of each leaf. There are single stage and two stage springs available for different applications. Primary and secondary stage leaves ensure that the vehicle’s ride remains uncompromised. As the spring is compressed under load, the heavier second stage leaves come into play to prevent excessive sag & remove high stresses from the primary stage.

    • Precision mandrel & die-formed
    • Oil quenched, hardened & tempered for maximum life.
    • Military wrap for safety
    • Accurately heat-treated
    • Manufactured from high grade spring steel
    • Anti-friction pads in most applications
    • Pre-stressed to maintain ride height
    • Diamond cut ends
    • Load rate tested
    • 2 year/40,000km warranty

 


Torsion Bars

Tough Dog Performance 4WD Torsion Bars offer a spring rate that is approximately 30% higher than OEM bars.

This dynamic increase in spring rate eliminates hard bottoming out when travelling off road and gives better handling in street applications. They can be installed with a moderate pre-load to raise the vehicle for better clearance off road, or to revitalise the handling characteristics at the standard height. These performance-proven, easy-to-install bars are especially beneficial when oversize tyres or frontal accessories are installed. Regardless of the torsion bar used, or the accessories fitted, a minimum 60mm of suspension droop (down travel) must be maintained.

 

 


Alignment

Gaining extra height on a tape measure is only a small part of fitting a suspension system. Improving the ride quality, capability and longevity of your suspension is the real key.

Quality alignment and supporting products are a must to ensure your vehicle retains its handling characteristics, as well as guarding against drivetrain vibration and premature tyre wear.

 


Panhard Rods

Adjustable panhard rods allow the axle to be re-centred under the vehicle after the height has been modified. Tough Dog panhard rods are bent from a single solid bar for strength, and are adjustable to cover a broad range of vehicle heights.

 


Diff locker

Designed especially for the Toyota Hilux solid axle front, this adjustable diff locker removes preload from the driver’s side spring caused by the suspension lift. This allows for maximum articulation and spring life.

 


Offset King Pins

Camber adjustment on live axle LandCruisers and Patrols can require an offset camber pin to be fitted. Available in 0.5, 0.75 and 1 degree of offset, these pins can help eliminate excessive and uneven tyre wear.

 


Transmission Spacers

Designed to reduce tail shaft angle and remove driveline vibration that arises from an out-of-phase drivetrain. The universal joints in a vehicle’s tailshaft must operate at the same angle to operate harmoniously. If the angle of one universal joint is different to the other, or the universal joints are forced to operate on an angle larger that within tolerance, the resulting vibration can be felt through the vehicle when driven. To restore the universal joints to harmony, Tough Dog spacer kits are available for vehicles that commonly suffer from vibration.

 


Castor Correction

Castor is the angle to which the steering pivot axis is tilted forward or rearward from vertical, as viewed from the side. Castor is important for vehicle steering response and stability. When a vehicle is lifted, the castor angle is adversely affected because of the change in the angles of the front radius arms. Tough Dog provide a range of products to adjust camber from two degrees through to seven degrees to ensure a reliable straight steering feel is maintained at any lift height provided in the Tough Dog range.

 


Accessories

Often it’s the attention to detail, and the finishing touches that can make all the difference.

We have a range of quality accessories to compliment your springs and shock, and complete the lift kit you need.

 


Urethane Products

Leaf spring based suspension set ups generally have a bias leaning towards load carrying capability over ride quality. The design and composition of the shackle hanger and bushing material can make all the difference to your ride quality. This assembly is the spring’s first part to move in response to uneven terrain and bumps in the road. Tough Dog urethane is stronger than rubber components and has greater longevity and resistance to deterioration from chemical exposure. Urethane bushes respond well to greasing during operation and are created to retain flexibility for ride comfort. When required, steel tubes in the centre of the bush are hardened and chemically treated to resist corrosion. All of this will keep your leaf sprung vehicle in positive contact with the road surface and give you better tyre and suspension component life. Replacement urethane bushes are available for all Tough Dog leaf springs as well as for a range of other suspension bushing locations in vehicles. Tough Dog also have a range of coil spring spacers to assist in levelling and trimming live axle coil vehicles. Poured as a single piece urethane, Tough Dog spring spacers are available in various heights, depending on the vehicle and application.

 


U-Bolt Kits

When U-bolts are tightened to secure the leaf pack in the vehicle from factory, the metal is stretched as a normal part of this process. It is important that U-bolts be replaced when a suspension system is changed, as a stretched U-bolt has lost its integral strength. The U-bolt will appear tight when re-used, but in fact it isn’t, this puts undue pressure on the centre bolts in the springs, causing them to move or snap which in turn allows the diff to move and the leaves to spread. Tough Dog U-bolts are manufactured using high tensile steel & are designed with the correct length of thread for larger, heavy duty leaf spring packs.

 


Greasable Shackles and Pins

Greasable pins and shackles help protect the bushes from premature wear because of the ingress of dirt and grit. Applying grease through the nipple forces grease through the joint and out, taking with it foreign objects. Greasable components are particularly important to vehicles exposed to outback dust or high salt level environments like boat ramps and beach driving.

 


Brake Hose Kits

Extended brake lines become a requirement for larger lift vehicles to prevent damage from stretching the existing lines. Tough Dog offer a brake line solution in both a tradition rubber style as well as a steel braided line for improved brake pedal response and feel.
