Code No. 21003-AN013
Low-friction double layer coated OEM replacement piston kit redesigned to achieve lighter weight and durability.
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.
1. High Strength
2. Ultra-light weight (piston : 352g / piston pins : 97g)
3. Low friction
New design bridge structure made from forged materials
Lightweight short piston pins
The number of oil jets on the intake side, where the major thrust loads are applied, has been reduced to one to ensure smooth oil lubrication between the cylinder wall and the piston skirt.
Lighter weight by eliminating excess thickness around the pin boss area
Piston skirts under lightening process for lightweight without losing strength.
Oil from the oil jet is directed to the center of the piston for cooling. Oil from the oil ring is directed to the piston pin for lubrication.
|Comp. ratio (t=1.2)||8.7||-|
*When used with 22001-AN001/VALVE SPG RB26DETT STEP2 and STEP2 Camshafts.
