Jeep Wrangler (2007-ON) JK LWB Petrol 3/2007-ON Tough Dog TDC337 Tough Dog Front Raised Coil Springs
TD-TDC337

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, making these coils a reliable choice for demanding applications.

The Tough Dog coils are constructed to retain their original memory even under heavy loads, resulting in a lighter yet more durable coil that can withstand rigorous conditions. Each coil undergoes a meticulous shot peening process to relieve internal stresses, ensuring longevity and performance stability.

Additionally, the coils are scragged and load tested to guarantee their strength and reliability. Formed on precision mandrels and hot formed to maintain spring memory, these coils are built to perform. The powder-coated finish not only enhances the aesthetic appeal but also provides excellent corrosion resistance, ensuring that they look great and last longer.

For those with additional accessories, Tough Dog offers a variety of spring rates to accommodate extra load or constant load carrying needs. The approximate lift height ranges from 30-40mm, with specific models designed for various configurations: TDC337 is suitable for setups with up to a steel bar, while TDC338 is compatible with steel bars or setups that include a bar and winch.

It is recommended to pair these raised springs with long travel shock absorbers to maximize performance and ride quality. Please note that the images provided are for representation purposes only and may not reflect the exact part number you are viewing.
