Direct OE replacement pistons designed to match original size, form, and function for a seamless install and dependable performance. Precision machined to tight tolerances to ensure exact form, fit, and accurate compression across operating conditions Lightweight design reduces reciprocating mass and bearing loads, delivering smoother engine operation and quicker response without sacrificing reliability Proprietary Grafal antifriction skirt coating (graphite impregnated resin) lowers drag, scuffing, friction, and cylinder bore wear to extend piston life Key attributes at a glance Function: worn or damaged pistons with an OE equivalent that preserves engine balance and timing Compatibility: Sized and toleranced to match OE specifications for engines originally using these pistons Size and fit: Engineered for precise fit within compatible cylinder bores and rings Material and coating: Graphite impregnated Grafal skirt coating for reduced friction and wear Performance: Improved engine response, smoother operation, and reduced bearing stress over time Use scenarios Routine engine rebuilds for passenger cars and light trucks that require OE specification pistons to restore original performance and reliability Performanceminded rebuilds where lowering reciprocating mass helps enhance throttle response and overall engine feel while maintaining durability Maintenance of mileage engines in fleets or service shops where reduced bore wear and smoother operation extend service life between major overhauls
