Tough Dog Suspension and Lift Kits, Gold Coast

Up to 75 mm in total, made up of no more than 50 mm from suspension and no more than 25 mm from larger tyres. Body lift blocks are not allowed without certification. This applies to 4WD type vehicles in ADR categories MC, NA and NB1, and the vehicle must still meet every other vehicle standard.

Not for the lift limit. TMR's current Minor Modifications information sheet (February 2026) treats vehicles with and without ESC the same, so the 75 mm limit applies to both. ESC must still work as intended after any change to ride height or GVM, and where certification is needed the Approved Person must hold evidence of that.

TMR counts tyre lift as half the increase in tyre diameter, so a tyre 50 mm larger in diameter adds 25 mm of lift. For MC, NA and NB1 vehicles an alternative tyre can be up to 50 mm larger in overall diameter than any size the manufacturer lists for that model. Speedometer accuracy must be maintained.

A lift of up to 150 mm is allowed with certification by a Queensland Approved Person. The 150 mm can be made up of up to 100 mm suspension, 25 mm tyres and 50 mm body blocks. Suspension changes beyond the minor limits are complex modifications that must follow a Queensland approved modification code.

Not automatically. The manufacturer can still refuse a claim if the modification caused the fault, and the factory warranty does not cover aftermarket parts. Those parts carry their maker's warranty instead, for example 4 years/unlimited km recreational on Tough Dog Foam Cell and adjustable shocks, 5 years/unlimited km on Outback Armour shocks and springs, and 2 years or 40,000 km on Pedders lift kits.

Yes. The Australian Automotive Aftermarket Association recommends telling your insurer about any modification. Check your policy wording, as undisclosed modifications can affect a claim.

It can. TMR requires ESC to keep working as intended after a ride height change. Some vehicles also lose factory features when the shocks are replaced; Tough Dog notes the LandCruiser 300 Sahara ZX's Adaptive Variable Suspension is lost when its shocks are fitted. We check what applies to your model before quoting.

Often not for a lift of 50 mm or less. Tough Dog warns that fitting upper control arms to vehicles lifted more than 50 mm may lead to premature ball joint failure, and Outback Armour's upper control arm warranty applies where the lift does not exceed 50 mm. Larger lifts can need correction parts, which is one reason they need certification.
