Transform your SUV’s off-road load capacity and highway stability with the commercial truck-tough RAW 4x4 Heavy-Duty Suspension Kit for the Isuzu MU-X Generation 1 (2013–2022), built on the robust Isuzu KB / D-Max platform. Born from a rich pedigree of heavy commercial vehicle engineering by Powerdown, this system replaces soft, fatigued factory components to provide up to 45mm of ground clearance — carefully optimised to maintain safe velocity and angular thresholds for the front independent CV axles.
Unlike the bakkie variants, the Gen-1 MU-X utilizes an all-coil independent front and multi-link rear suspension layout — making this a lighter, more refined lift solution than leaf-spring bakkie kits. Whether you’re packing a Quick Pitch Quick-en-Suite Box Unit, an interior drawer system, or towing an off-road camper trailer, the upgraded front coils and RC-MUX13R-HD Constant-Load Rear Springs stop rear-end sag dead in its tracks. Equipped with massive-bore Nitro Max shocks with 35–45mm bore pistons in up to a 61mm outer tube and multi-lip HNBR high-temperature seals built to keep fine bush dust out.
