Jeep Wrangler (2007-ON) JK LWB Diesel 3/2007-ON Tough Dog TDC339 Tough Dog Rear Raised Coil Springs
TD-TDC339

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 lighter, more durable coil that can withstand the rigors of off-road and heavy-duty applications. Each coil undergoes a rigorous manufacturing process, including shot peening to relieve stress, scragging, and load testing to ensure reliability and performance. Formed on precision mandrels and hot formed to maintain spring memory, these coils are built to last.

To enhance both aesthetics and durability, Tough Dog coils feature a powder-coated finish that provides excellent corrosion resistance. If your vehicle is equipped with additional accessories, Tough Dog offers a variety of spring rates tailored to accommodate these modifications or constant load carrying requirements.

Constant Load refers to the weight that is permanently added to the vehicle, 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 capabilities, ensuring the best performance on and off the road.

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