Poly-Locs

Features a unique, heavy duty internal interlocking feature. The blow-out proof design limits expansion of the mount on the driver's side, while limiting compression on the passenger's side. Both sides work simultaneously to provide a rugged mechanical lock to keep your engine in place under hard acceleration.

Our Poly-Loc Mounts are available for small block, big block and original Hemi passenger car biscuit-style mounting systems from 1962-74, and for '72-86 full size truck, big block and small block. Check out all the options available below. Read more »
