With over 9 months of engineering and development from ReadyLift and more awesome features than we could possibly mention, this 6" lift kit features HD angled and offset top mount strut extensions that realigns the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle larger wheels and tires.
