Description

If you're building a high-performance engine that demands tight tolerances and consistent ring seal, KB Performance pistons are engineered to deliver. The T-5 heat-treated 390 hypereutectic aluminum construction allows installation at tighter clearances than conventional pistons, reducing piston rock and minimizing blow-by for better combustion efficiency. Each piston is diamond-machined to within one gram weight tolerance and half-thousandth-inch concentricity, ensuring the kind of precision that separates a well-tuned engine from a mediocre one.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
