Low-friction double layer coated OEM replacement piston kit redesigned to achieve lighter weight and durability. Compatible with STEP2 camshaft.

Features

• High Strength
  • Adapting truss structure for improved structural rigidity.
  • Made of highly heat resistant & durable A2628 alloy.
• Ultra-light weight
  • optimized profile for shorter skirt height and narrower skirt width to reduce weight.
  • Machined to reduce excess thickness parts to achieve ultra lightweight.
• Low Friction
  • double -layer moly and PTFE coating to reduce friction.
  • Reducing axial load by offsetting piston pin

Double-Layer Coated

The outer layer is a moly coating effective for sliding under high loads. The inner layer is a PTFE coating effective for sliding under high rotation.
