Product Info
King Springs Coil Springs Rear Pair KDRR-43SP4 are engineered suspension components designed for vehicles requiring heavy-duty rear spring support. Built from high-stress X5K spring steel, these coil springs deliver the strength and load-carrying capability demanded by Australian driving conditions, whether on road or off.
King Springs develops advanced spring designs using sophisticated CAD programmes, and the X5K material represents a new generation of high-stress steel that reduces weight by approximately 30% compared to conventional spring steels while increasing travel and durability. This premium material, proven in leading V8 Supercar teams since 2007, is now integrated into passenger and 4WD designs at no extra cost. Phosphate and epoxy powder coatings provide maximum corrosion protection against salt, moisture and environmental wear.
