When performance leaf springs are added to your 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.

Thuren Shackles were 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 three mounting positions.

Fitment:

2003-2013 4x4 2500
2003-2012 4x4 3500
2005-2013 Power Wagons.

Sold in Pairs
The grease-able 75D bushing at the shackle pivot provides smooth bind-free shackle swing.
3 position 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 Long Travel leafs installed.

- We have been informed these can be used as a lowering shackle on 2003-2012 2x4 2500/3500 trucks.
