Mitsubishi Challenger (0) PA II Coil Rear 6/2000-2007 Tough Dog TDC640 Tough Dog Rear Raised Coil Springs
TD-TDC640

Designed and manufactured in Australia using high-quality German X5K spring steel, Tough Dog coils are engineered to optimize performance while utilizing less material. This innovative design ensures that the coils deliver exceptional ride quality and impressive load-carrying capabilities. Even under heavy loads, these springs maintain their original memory, resulting in a lighter yet more durable coil that can withstand rigorous demands.

Each coil undergoes a meticulous manufacturing process, including shot peening to relieve internal stresses, scragging, and rigorous load testing. Formed on precision mandrels and hot-formed to preserve spring memory, these coils are built to last. The powder-coated finish not only enhances the aesthetic appeal but also provides excellent corrosion resistance, ensuring longevity in various environments.

For vehicles equipped with additional accessories, Tough Dog offers a range of spring rates tailored to accommodate extra weight or constant load scenarios. Constant Load refers to the weight that remains on the vehicle at all times, such as fixed accessories like canopies, steel trays, drawer systems, fridges, toolboxes, rear bars, or spare wheel carriers. Selecting the appropriate spring rate is crucial for optimizing vehicle performance and load management.
