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.

Rated for 1.000hp
Made from special steel alloys that combines optimal mass with high resistance.
Piston Rings 81mm SPA DLC series
Specifications:
1º 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.
3º ring 2.0mm – 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.
