Finish your shackle flip right — heavy-duty rear shackles built to pair with your Squarebody flip kit.

This is the CFM Industries rear shackle set, made specifically to complete a shackle flip on your Squarebody Chevy and GMC build. A shackle flip is one of the most popular ways to get rear lift and better geometry out of a leaf-sprung Squarebody — and these shackles are the piece that ties it all together, built heavy-duty to handle the load and the abuse.

Available in multiple lengths so you can dial in exactly the lift and stance you're after, these give your rear suspension a strong, purpose-built link instead of worn-out factory shackles or guesswork parts.
