Land Rover Discovery (1991-1999) Series I 4/1991-1999 Tough Dog TDC518 Tough Dog Rear Raised Coil Springs
TD-TDC518

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.

These springs are crafted to retain their original memory even under heavy loads, resulting in a lighter yet more robust coil that can withstand rigorous demands. Each coil undergoes a meticulous shot peening process to relieve internal stresses, followed by scragging and load testing to ensure reliability and performance.

Formed on precision mandrels and hot formed to preserve spring memory, Tough Dog coils are finished with a durable powder coating that not only enhances their aesthetic appeal but also provides excellent corrosion resistance.

For vehicles equipped with additional accessories, Tough Dog offers a variety of spring rates tailored to accommodate extra weight or constant load scenarios. Constant Load refers to 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 setup and load management.

For optimal performance, it is advisable to pair these raised springs with long travel shock absorbers to enhance the overall suspension system.
