Innovative high performance piston skirt design that provides:
1. Smaller piston to bore clearance
2. Less noise
3. Better ring seal
4. Higher power
5. Durability
Features:
Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions.
Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal.
Pin oil lubrication by broaches and oiler to reduce friction and increase durability.

PistonRings 86mm SPA DLC series
Specifications:
1 ring 1.5mm Made from carbon steel, which is 35% stronger than cast iron and about 30% lighter. DLC treated, which is the application of carbon particles, that provides higher resistance and lower friction.
2 ring 1.5mm Made from cast iron.
3 ring 3.0mm Made by 3 parts, providing easy handling, better oil film stability and improvement in oil removal by the lubrication holes due to its optimized design.
