Beef up your front leaf spring shackles — heavy-duty plates that replace the weak factory pieces.

These are the CFM Industries front HD shackle plates, built for 1973–1987 Squarebody Chevy and GMC K-series 4x4 trucks, K5 Blazers, and GMC Jimmys. The factory front shackle plates on a leaf-sprung Squarebody are a known weak point — they bend and flex under hard use. These replace them with heavy-duty plates that hold up to the abuse of real off-road wheeling.

It's a simple, affordable upgrade that strengthens a part most people don't think about until it fails. If you're wheeling your truck or building out your front suspension, this is cheap insurance for your front end.

Why It Works

• Heavy-duty replacement — stronger than the factory front shackle plates they replace.
• Fixes a weak point — factory plates bend and flex; these don't.
• Built for K-series 4x4 — fits '73–'87 K10, K20, K30 trucks, K5 Blazers & Jimmys.
• Affordable upgrade — cheap insurance for your front leaf spring setup.
• Built tough — made for off-road and hard wheeling.
