Rough Country offers a simple solution for gaining more height with their 3.5" lift kit for the 2500HD & 3500HD models without rear overload springs (models with overloads use 97530). These forged aluminum upper control arms are over-built, to add strength and range of motion. The control arms include durable bushings and are designed to correct the geometry to factory-like angles, maintaining a factory-like ride. The addition of a new set of N3 shocks brings new life to your suspension! Rough Country combines high quality with a low price, making this kit an obvious choice.
