Description

It features an asymmetrical FSR (Forged Side Relief) forging design that allows for popular stroke and rod combinations while eliminating reluctor wheel clearance issues. This design maintains a larger skirt on the major thrust side for strength and a smaller skirt on the minor thrust side to reduce friction.

These pistons are machined for 1.2mm, 1.5mm, and 3.0mm rings and include combination 12° & 15° valve pockets. They also feature grain flow optimized forging, lateral gas ports, ceramic crown coating, perfect skirt coating, accumulator groove, and double pin oiling. Upgraded 9310 pins and locks are included.
