Wiseco S722C DLC-Coated Piston Wrist Pin 22x60mm 9310 Steel

The Wiseco S722C is a precision-machined, DLC (Diamond-Like Carbon) coated piston wrist pin engineered for high-performance and racing engine applications. Measuring 22mm outer diameter × 60mm length × 10.57mm wall thickness, this pin is manufactured from 9310 nickel carbon steel — a case-hardened alloy renowned for its exceptional toughness and fatigue resistance under extreme mechanical loads.

The DLC coating dramatically reduces friction and surface wear between the pin and pin bore, improving longevity and efficiency under sustained high-RPM conditions. The lightened, straight-wall design reduces reciprocating mass without compromising structural integrity, making it an ideal upgrade for performance builds where every gram counts.

Key Features:

• DLC (Diamond-Like Carbon) coating for reduced friction and extended wear life
• 9310 nickel carbon steel construction — high-strength, case-hardened alloy
• Dimensions: 22mm OD × 60mm length × 10.57mm wall thickness (0.866" OD × 2.362" length)
• Weight: approximately 137 grams
• Precision-machined for tight tolerances and consistent fitment
• Lightened design reduces reciprocating weight for improved engine response
• Compatible with Wiseco forged pistons and select OEM piston applications
• Round wire lock retention type
• Sold individually — order quantity as needed for your application

Wiseco wrist pins are built to handle the extreme demands of racing and high-performance street engines. The S722C's DLC coating makes it a premium choice over standard uncoated pins, particularly in forced-induction or high-compression builds where pin bore temperatures and loads are elevated.
