Mercedes-Benz X Class (0) X350D 2017-On Tough Dog TDC774H Tough Dog Rear Raised Coil Springs
TD-TDC774H

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 rigorous process, including shot peening to relieve stress, scragging, and load testing to ensure reliability. Formed on precision mandrels and hot formed to maintain spring memory, these coils are built to last.

To enhance durability and aesthetics, Tough Dog coils feature a powder-coated finish that provides excellent corrosion resistance. If you have additional accessories fitted to your vehicle, Tough Dog offers a variety 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, draw systems, fridges, toolboxes, rear bars, or spare wheel carriers. Selecting the appropriate spring option is crucial for optimizing your vehicle's setup and load-carrying performance.

For optimal performance, it is recommended to pair these raised springs with long travel shock absorbers.
