CalOffroad Medium to Heavy Duty Platinum Series Front Coil Springs are designed and manufactured specifically for the Isuzu Dmax. Our coils are developed and manufactured in Australia, made from high-grade Australian made steel and utilising the latest tapered wire technology, allowing us to tune a rebound rate into the coil, assisting the shock for a less aggressive rebound and less shock fade under extreme conditions. Dyno testing has been carried out to ensure the coil rate is tuned to match the shock valving, achieving the smoothest possible ride. These coil springs are a must have if you are looking for a lift or if your Dmax is running a bullbar, winch or any accessory with a heavy front load, as they will support the extra weight on your truck, as well as maintain its height.
