1973-87 Chevy 2 inch Shackle Priced As Pair - Easy Install - Instructions - Yes ear leaf spring shackles are commonly used to “Level” trucks. For those of you who just can’t stand the “stink bug” look of factory stances, the lowering shackle is for you! Typical drop is two inches and fairly simple to install. You simply remove the factory shackle and replace it with a longer drop shackle. Be sure to use the one designed for your particular truck! The leaf spring shackle is located on the rear of the leaf spring and is the only part of the rear suspension that is designed to move. When you hit bumps and dips, which cause the rear end to move up and down the leaf spring actually gets longer and shorter relative to the frame. It is the shackle that pivots forward and back with the leaf spring while being firmly attached to the frame. A good tip when installing shackles is to lubricate the bushings and bolts and be careful to not overtighten. It is possible to tighten so much that the shackle will not pivot, which can cause the truck to ride horribly, and affect ride height. Of course you the pivot bolt needs to be tight and you should use the factory locknut, just don’t set your pneumatic wrench to kill and run it down until it stops! DJM Suspension SH1012-2
