Land Rover Discovery (1999-4/2005) Series II 3/1999-4/2005 Tough Dog TDC508H Tough Dog Raised Coil Springs
TD-TDC508H

Designed and manufactured in Australia using high-quality German X5K spring steel, Tough Dog coils are engineered to optimize material usage while delivering exceptional ride quality and 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 demanding conditions.

Each coil undergoes a rigorous manufacturing process, including shot peening to relieve internal stresses, scragging, and load testing to ensure reliability. The springs are formed on precision mandrels and hot-formed to preserve their spring memory, ensuring consistent performance over time. A powder-coated finish not only enhances the 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 is permanently added to the vehicle, such as canopies, steel trays, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers. Selecting the appropriate spring option is crucial for optimizing vehicle setup and load management to achieve the best performance.

Approximate Lift Height: 25-35mm TDC508 - 0-300kg Light Load TDC508H - 300kg Constant Load

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