RAW 4x4 Heavy-Duty Suspension Lift Kit – Isuzu D-Max / KB Series (2013–2022)

Fix your bakkie’s load handling and upgrade its trail performance with the commercial truck-tough RAW 4x4 Heavy-Duty Suspension Kit for the Isuzu D-Max / KB Series (2013–2022), covering RT50 and RT85 platforms. Born from a legacy of heavy commercial vehicle engineering by Powerdown, this system eliminates the harsh unladen leaf chatter and severe tail sag of the stock bakkie while providing up to 50mm of ground clearance — carefully limited to preserve factory independent front CV axle boot geometry.

Whether you’re packing a Quick Pitch Quick-en-Suite Box Unit, an overlanding canopy setup, or heading cross-border on corrugated gravel routes, the upgraded front coils and R-ISU13B Constant-Load Leaf Springs stop rear-end sag dead in its tracks. Equipped with massive 45mm-bore Nitro Max shocks in a 60mm outer tube with high-pressure HNBR multi-lip dust and oil seals built to withstand harsh trail grit, this kit completely eradicates dampening fade over hours of brutal off-road driving.
