Formed Head Relief Design Pistons

The FHR (Formed Head Relief) series are an ''Off The Shelf'' piston loaded with premium features that are usually found in specialty custom made pistons. FHR pistons have valve reliefs that are formed in as the piston blank is pressed into the die. Many of the domed models are solid which allows tailoring the dome height for a specific compression ratio. Forged from 4032 Alloy material containing 11% silicon content which controls the thermal expansion so a tighter piston to wall clearance may be used over the 2618 alloy. The additional silicon wil also increase wearability on the skirts and pin bores making this an ideal material for street and some boosted applications.

Features
  • Premium 4032 Alloy
  • Die Formed Valve Reliefs
  • Top Land Mini Groove Technology Reduces Friction
  • Diamond Finished Piston Skirts
  • Second Land Accumulator Grooves Increase Stability in the Bore
  • Tru-Arc Lock Rings
  • Spacer rings included in short compression heights that intersect the wrist pin bore
  • Sold in Sets (except when noted as 1 piston per package)
