KB Performance Pistons KB115.030 KB Series Flat Top Piston Set

Upgrade a small block Ford engine with the KB Performance Pistons KB115.030 piston set. This set includes eight hypereutectic, flat-top pistons designed around a 4.030-inch bore and a 1.608-inch compression height.

These groove specifications identify the intended ring package dimensions and should be matched with compatible rings during assembly. The hypereutectic construction is part of the KB Series design and supports a purpose-built piston solution for small block Ford applications.

Verify bore, compression height, ring groove requirements, and other engine specifications before installation to ensure the components are appropriate for the intended application.
