CHRYSLER 408 ROD 6.123 STEP DISH +23.5CC 2V NO QUENCH DOME KB HYPER PISTON SET

The Keith Black KB416-080 piston is a hypereutectic piston designed for high-performance applications like marine, drag race, circle track, street, or towing builds. It features a low expansion 390 alloy with 16% silicon for tighter piston-to-wall running clearance.

This piston set includes a set of 8 pistons with fully machined head and valve reliefs, triple spiral lock rings, and CNC machined pin bores for accuracy. It also features an accumulator groove for compression ring seal, machined oil returns, diamond finished skirts, and mini grooves to reduce scuffing and overheating. Wrist pins and spiral locks are included, but piston rings are sold separately.
