The usable payload of many 4X4 vehicles today is minimal. Additional basic optional equipment and two or three adult male occupants will bring the vehicle close to its legal maximum weight (GVM) in many cases. Add long range fuel tanks, bull bars, winches, side steps, roof racks, recovery gear and a payload of camping equipment or an industrial type custom body and the vehicle will ultimately exceed the Original Equipment allowable Gross Vehicle Mass.

Original Equipment suspension is designed for comfort above all other considerations, thus load carrying and performance can be compromised. Whereas, GVM designed suspension systems come with matched components for the ultimate in performance, load carrying, and handling.

Our GVM kits are fully track tested in conjunction with a Certified Automotive Engineering Signatory over many days to achieve maximum stability, braking performance, ADR (Australian Design Rules) conformity and operator comfort, before test data and documentation are forwarded to the DEPARTMENT of INFRASTRUCTURE, TRANSPORT, REGIONAL DEVELOPMENT and LOCAL GOVERNMENT for full analysis.
