SZM DLC PISTON WRIST PINS (PINS D. 23 x PIN L. 63.6) HEAVY DUTY

Heavy duty, DLC-coated wrist pins measuring 23 mm outer diameter and 63.6 mm length are high-performance engine components  and they're a highly specific footprint common in specialized high-horsepower automotive builds. The diamond-like carbon (DLC) coating reduces friction, extends pin lifespan under extreme cylinder pressures, and provides superior wear protection in high-RPM or boosted applications

Key Technical Advantages of DLC Pins

Diamond-Like Carbon (DLC) Coating: This ultra-thin, metal-free carbon barrier increases surface hardness far beyond treated tool steel. It drops the sliding friction coefficient down to roughly 0.1, unlocking marginal horsepower and managing intense localized head.

Bushingless Compatibility: The extreme lubricity allows the pin to safely run directly against steel small-end connecting rods without requiring a traditional bronze bushing.

Anti-Galling Protection: In high-vacuum, high-boost, or dry-sump environments where temporary oil starvation can occur at high RPM, DLC prevents the metal-on-metal welding (galling) that destroys pistons and rods.
