RAW 4x4 Heavy-Duty Suspension Lift Kit – Isuzu MU-X (2022+)

RAW 4x4 Heavy-Duty Suspension Lift Kit – Isuzu MU-X (2022–Present)

Transform your modern SUV’s load capacity and highway stability with the commercial truck-tough RAW 4x4 Heavy-Duty Suspension Kit for the Isuzu MU-X (2022+), covering LSE, LS, and flagship Onyx 4x4 models. Born from a rich pedigree of heavy commercial vehicle engineering by Powerdown, this system replaces soft factory components to provide up to 45mm of ground clearance — carefully optimised to maintain safe velocity and angular thresholds for the independent front CV axles and rear multi-link geometry.

Unlike its D-Max bakkie sibling, the MU-X features a more refined multi-link rear suspension using coil springs rather than heavy-duty leaf packs — making this a lighter, more refined lift solution. 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-MUX22R-HD Constant-Load Rear Springs stop rear-end sag dead in its tracks. Equipped with massive 45mm-bore Nitro Max shocks in a 61mm outer tube with multi-lip HNBR high-temperature seals built to keep fine bush dust out.
