This shackle kit increases the bolt size from 7/16" to 1/2" and increases the side-plate thickness to 3/8" for improved durability. Grade 8 bolts included for maximum strength, shackles are gold zinc plated for corrosion resistance. The shackles are 1/2" longer than stock to help keep your lift springs from hitting the frame. This technically lifts the truck 1/4" but is truly intended to keep the spring from hitting the frame.
The greasable shackles use drilled/cross-drilled bolts and drilled inner sleeves to channel grease to the bushings. You'll get longer bushing life, a smoother ride, and virtually eliminated squeak with the greasable kit. We use ORD exclusive hard compound bushings for greater bushing life and recently upgraded to a 4130 chromoly steel sleeve for even more durability.
The larger bolt is a 30% strength upgrade, drilling the hole to make the bolt greasable only decreases the strength by 1%. The greasable system is a win-win for strength and durability/longevity.
