Land Rover Defender (1992-On) 90; 110; 130 Series 1992-On Tough Dog TDC504 Tough Dog Raised Coil Springs
TD-TDC504

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 superior ride quality and exceptional load carrying capabilities, allowing the spring to retain its original memory even under heavy loads.

The result is a lightweight yet robust coil that can withstand the rigors of demanding conditions. Each coil undergoes a meticulous process, including shot peening to relieve stress, scragging, and rigorous load testing. Formed on precision mandrels and hot formed to preserve spring memory, these coils are built to last.

Finished with a durable powder coating, Tough Dog coils not only perform exceptionally but also resist corrosion, ensuring longevity and aesthetic appeal. If you have additional accessories fitted to your vehicle, Tough Dog offers a range of spring rates tailored to accommodate these modifications or constant load carrying.

Constant Load refers to the weight that is permanently added to the vehicle, such as fixed accessories like canopies, steel trays, draw systems, fridges, tool boxes, rear bars, or spare wheel carriers. Selecting the appropriate spring option is crucial for optimizing your vehicle's setup and load carrying performance.

Approximate Lift Heights are as follows: TDC518 - 0-300kg Light Load, TDC518H - 300kg Constant Load, and TDC504 - 500kg Constant Load. For optimal performance, it is advisable to pair these raised springs with long travel shock absorbers.
