Better suspension geometry and articulation — without adding lift you don't want.

This is the CFM Industries zero-lift shackle flip kit, built for 1973–1991 Squarebody Chevy and GMC K-series 4x4 trucks, K5 Blazers, and GMC Jimmys. A shackle flip is one of the best ways to improve how a leaf-sprung Squarebody's rear suspension works — but most flips also jack the back of the truck up. This kit is designed to give you the improved geometry and articulation of a flip while keeping your ride height where it is.

If you want your rear suspension to flex and perform better off-road but you're happy with your current stance — or you're building to a specific ride height and don't want a flip fighting you — this is the setup. Adjustable, purpose-built, and made to upgrade your geometry without the lift.

Why It Works

• Zero lift design — better geometry and articulation without raising your ride height.
• Adjustable — dial in your rear suspension setup the way you want it.
• Better articulation — get more flex and performance out of a leaf-sprung rear end off-road.
• Built for K-series 4x4 — fits '73–'91 K10, K20, K30 trucks, K5 Blazers & Jimmys.
• Optional HD shackles — add heavy-duty shackles to complete the setup.
