Grommets, Bushes & Bump Stops: The Small Parts That Make a Big Difference

29 July 2025

Back to all articles

They cost a few dollars each, but the right grommets and bushes keep water, fumes and rattles where they belong.

Grommets, bushes and bump stops are the parts nobody photographs — until one is missing. Grommets seal the holes where cables and pipes pass through the firewall and floor; bushes cushion moving parts; bump stops protect the suspension at full travel.

Why they matter

A missing firewall grommet lets exhaust fumes, heat and water into the cabin. Perished bump stops let metal hit metal over bumps. Cracked body bushes let the car drum and rattle. Replacing them is one of the cheapest ways to make an old car feel tight again.

Buy the universal packs

We stock model-specific grommets as well as universal grommet and bump-stop assortments, which are handy to have on the bench during any rebuild so you are never held up by a two-dollar part.
