Ditch the weak factory clamshell mounts — heavy-duty replacements built to hold your engine put.

These are the CFM Industries heavy-duty replacement motor mounts, built for 1973–1991 Squarebody Chevy and GMC 4x4 trucks, K5 Blazers, GMC Jimmys, and Suburbans. The factory "clamshell" mounts these trucks came with are a known weak point — they crack, collapse, and let the engine shift around, especially once you're putting down power or wheeling hard. These replace them with something built to actually last.

If your factory mounts are tired, broken, or you just want to do it once and never think about it again, this is the upgrade. Solid, heavy-duty, and built to keep your engine planted where it belongs.
