Piston Pin H-13 Steel .990Dx930L x .250W

The Piston Pin H-13 Steel .990Dx930L x .250W from TREND PERFORMANCE PRODUCTS is a precision-engineered wrist pin designed for high-performance marine engine builds. This 0.990-inch diameter piston pin measures 2.930 inches long with a 0.250-inch thick wall, offering the dimensional accuracy and load-bearing strength demanded by serious offshore boaters and performance engine builders who push their vessels to the limit.

H-13 steel is the industry standard for piston pin applications where reliability under extreme conditions is non-negotiable. The thicker 0.250-inch wall construction resists deflection and fatigue failure during high-RPM operation and heavy throttle application—critical for twin-engine rigs and turbocharged setups where instantaneous power delivery puts stress on every internal component. The spiral lock design secures the pin within the piston bore without the need for separate snap rings, simplifying assembly and reducing the risk of lock-related failure. This configuration also allows for tighter manufacturing tolerances and cleaner internal geometry that resists carbon buildup in salt-air environments.

Engine builders and marine mechanics depend on TREND PERFORMANCE PRODUCTS pins for mid-range and high-displacement engine rebuilds where OEM-equivalent parts don't meet performance targets. Weekend fishermen running stock or mildly modified engines rarely need replacement piston pins; this product is engineered for the owner who has bored an engine block, upgraded to forged pistons, or installed stroker cranks. The precise 0.990-inch diameter and 2.930-inch length ensure proper fit in engines engineered for these specifications—incorrect dimensions create lateral movement, piston slap, and accelerated ring wear.

Verify your engine's original pin dimensions before ordering; a piston pin is application-specific and will not interchange with other sizes. This is a single pin—many rebuild kits require multiple pins depending on cylinder count, so confirm your total quantity needed before checkout.
