KB 392 Hemi Pistons

Keith Black Hypereutectic 392 Hemi Piston Sets

KB 392 Hemi Pistons

High performance KB hypereutectic 392 Hemi pistons offer a significant performance improvement for your engine, at a very affordable price. We have these piston sets in 30, 40 and 60 oversizes. If you are rebuilding a Chrysler 392 Hemi engine and are looking for improved performance, without the higher cost of forged pistons, KB performance pistons are an excellent alternative for many street, muscle car restoration, cruising and street / strip applications.

We do not recommend hypereutectic pistons for use with superchargers, turbochargers, nitrous systems or for serious racing engines. We recommend forged pistons for those applications and we have them listed on our website here: Forged 392 Hemi Pistons

  • Fully machined head and valve reliefs
  • Accumulator groove to aid with compression ring seal
