Lowering Drop Shackles
Lowering shackles are a great, easy way for you to gain a few inches of drop at the rear axle. Rear leaf spring shackles are built to move the leaf spring up and in turn moves the axle closer to the frame. Some shackles in combination with other hardware may require the installation of a c-notch. When installing your shackle you can adjust the dropped height with alternate leaf spring mounting holes.
You can also combine your shackles with other rear lowering hardware to maximize your overall rear axle drop.
Shackle pairs are available for many makes and models.
