⚠️ CRITICAL FITMENT NOTE:
These retainers are designed for 0.927" diameter wrist pins used in traditional Small Block Chevy engines.
DO NOT USE with LS-series engines (.943" pins), Big Block Chevy (.990"+ pins), or metric applications.
Always verify your piston pin groove dimensions and retainer style (C-Clip vs. Spirolox vs. Wire Lock) before installation.
Improper installation can cause catastrophic engine failure.

Pro Builder Tip: Always replace wrist pin retainers in complete sets during engine assembly. Mixing old and new clips can lead to uneven stress distribution and premature failure. For high-RPM or forced-induction applications, consider upgrading to double-wound Spirolox or wire-lock style retainers for enhanced security.
