Description

Icon FHR (Forged Head Relief) Series pistons, made from 4032 forged alloy, are designed for performance with budget in mind. They feature true arc-style lockrings, broached pin holes, and break-through oil returns. The solid dome and formed head relief design allow for custom machining to achieve desired compression ratios. The 11% silicon content enables tighter piston-to-wall clearances, reducing friction and extending piston life. Includes wrist pins and spiral locks. Piston rings are not included.
