Carrillo 866-2350-23A5CX CPP High-Performance Piston Pin 0.866" x 2.350" x 0.230"

The Carrillo 866-2350-23A5CX is a high-performance piston pin (wrist pin) engineered for demanding motorsport and high-horsepower engine applications. Measuring 0.866" outer diameter × 2.350" length × 0.230" wall thickness, this precision-machined pin serves as the critical link between the piston and connecting rod, withstanding extreme alternating loads, shearing forces, and bending stress during high-RPM operation.

Key Features:

• Precision Dimensions: 0.866" OD × 2.350" length × 0.230" wall thickness for exacting fitment
• Case Hardened: Computerized gas hardening process for superior surface hardness and durability
• Gun-Drilled ID: Multi-stage internal honing reduces weight while maintaining structural integrity
• Cryogenic Treatment: Subzero heat-treating process improves material strength and refines grain structure for enhanced fatigue resistance
• Precision Ground Ends: Finished with internal radius for reduced stress concentration
• Straight Wall Design: Minimizes pin bore galling on the ends for longer service life
• Weight Tolerance: Held to ±1 gram for balanced rotating assembly performance
• 100% Rockwell Tested: Every pin is individually hardness-tested before leaving the factory

CP-Carrillo piston pins are manufactured to meet the rigorous demands of forced induction, nitrous, and naturally aspirated high-performance engines. These pins are designed for use with CP-Carrillo pistons and are not intended as OEM replacements. For applications exceeding 850 horsepower, heavy-duty wrist pins are strongly recommended.
