We are pleased to announce that we have received Federal approval for GVM Upgrades to suit Toyota Landcruiser 200 Series.

The Ironman 4×4 GVM upgrade can increase your payload by up to 700kg, bringing the GVM up to 4000kg.

The usable payload of many 4×4 vehicles today is minimal. By adding basic vehicle accessories or work tools and having two or three adult passengers, your vehicle will be brought close, if not over, its legal maximum weight, also known as the Gross Vehicle Mass (GVM).

Commonly, many 4×4 owners will fit and carry optional accessories like long range fuel tanks, bull bars, winches, side steps, roof racks, recovery gear, a payload of camping equipment or an industrial type custom body. Add these accessories with a tow ball weight from a trailer, camper trailer or caravan and it is almost guaranteed to be over.

With each accessory carried by the vehicle, the responsiveness of the Original Equipment (OE) suspension changes. The OE manufacturer designs their suspension kits for comfort above all else and the addition of load can compromise ongoing performance.

This is where Ironman 4×4 suspension and GVM upgrades come in.


Creating safe and appropriate dynamic handling at higher than maximum original weight ratings requires careful consideration.

Forces generated by a heavily loaded vehicle in rough terrain can be considerably higher than those generated during normal driving.
The vehicles springs must be matched to the load for optimum ride height and body control.

If the shock absorbers do not possess the correct amount of damping resistance, the vehicle will remain highly susceptible to a rollover accident.

By building high critically damped shock absorbers, we have created the safest and best handling after-market suspension possible at GVM weights and beyond.

Foam Cell Pro Shock Absorbers are perfectly suited to increased load in demanding and hot off-road environments, compared to gas shocks they distribute the oil more evenly around the shock body resulting in more dissipation of heat and long lasting control.
