GVM upgrades from Jmacx

A GVM upgrade is often required and something that many vehicles are now being fitted with.

The biggest issues with common GVM upgrades is that they cut into your towing capacity & have unrealistic axle load ratings. Our leaf spring suspension systems have GVM upgrades up to 4200kg whilst also maintaining a full 3500kg braked towing capacity, this means you can load your vehicle to 4200kg and still tow 3500kg.

The Jmacx leaf spring GVM upgrades include a replacement diff housing which is far stronger than the standard unit and allows you a rear axle load of 2700kg, this high axle load enables you to load your vehicle to GVM without exceeding your rear axle weight. This replacement diff housing also corrects the vehicles track and features a pair of upgraded chromoly axles.

All Jmacx GVM kits feature a brake upgrade so that the vehicle can safely brake when heavily loaded.

Coil conversion from Jmacx

A Jmacx coil conversion offers all of the advantages that the leaf spring kit has and more.

A coil conversion offers better ride comfort, improved off-road capability and superior handling. The coil conversion also allows us to go an inch higher, so we can legally install 4 inches of lift and a 35 inch tyre. No matter the brand, with a leaf spring suspension system you need to maintain a constant load to allow the suspension to work effectively.

However with a coil spring suspension system you do not have to be loaded to GVM to experience good ride comfort, this allows the vehicle to be more universal with varying payloads. The Jmacx coil conversion is a complete bolt in system that requires no welding and uses all genuine bearings & seals, this means it is much easier to find spare parts in remote areas than a kit which uses custom parts.

Jmacx not only offer full vehicle solutions, but also offer a range of individual components to enhance handling, performance & braking. These products include diff housings, brake boosters, brake lines, radius arms, u-bolt clearance plates, stronger axles, speedo correctors, exhaust systems & more.
