Pin upgrades to suit CP pistons. These have the same external diameter but a smaller internal diameter. This gives better strength.

• Sold as a set of 6
• 100% Rockwell tested
• Case hardened (computerized gas process)
• Gun drilled I.D.’s with 3 stages of I.D. honing
• Weight tolerances +/- 1 gram
• Precision ground ends with I.D. radius
• Straight wall design to reduce pin galling on ends
• Available with chamfered ends for Wire Locks
• Cryogenically treated (subzero heat-treating process)
for improved material strength and grain structure
