THUREN HIGH PERFORMANCE LEAF SPRING SHACKLES

CJC Off Road Verified independent store

Fits 2003-2013 4x4 2500 trucks, 2003-2012 4x4 3500, and 2005-2013 Power Wagons. The greaseable 75D bushing we use as the shackle pivot provides smooth bind-free shackle swing. 3 po sition height adjustable, when used with OEM or other brand leafs. Stock height, 3/4" lift, and 1-3/4" lift options. Thuren LT leafs must use the longest span mounting, so they become non-height adjustable, with Thuren LT leafs. When performance leaf springs are added to the truck, the extension and compression of the leaf springs length, can bind up the tight rubber OEM shackle bushing. Removing every bit of friction counts. This shackle was originally designed as the key component to our Long Travel extended Leafs, but will fit any truck with OEM or aftermarket leafs. As an added benefit, we added the ability to tune the rear suspension height with multiple mounting positions. Show more
