Piston Pin Locks & Wrist Pin Retainers

Piston pin locks (also called wrist pin clips or circlips) secure the wrist pin inside the piston, preventing it from walking out and contacting the cylinder wall. A dislodged pin lock causes catastrophic cylinder wall damage, so proper installation and quality retention hardware are essential during any piston assembly.

OneFastShop carries piston pin locks including wire-type pin locks, spiral locks, Teflon buttons, round wire clips, and pin retention hardware for popular forged and OE piston assemblies.

Every piston pin lock at OneFastShop ships brand-new and ready to install. Whether you're assembling pistons on a fresh engine build, replacing pin locks during a rebuild, or stocking spares for race motor assembly, OneFastShop has the pin locks. Shop the full piston pin locks collection today.
