Note for Pistons, Rings, Rotors, Rods and engine internals
Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Piston and Ring Kit, Hypereutectic, Flat, 4.030 in. Bore, Chevy, Small Block, Kit
KB Performance Hyper piston and ring kits are offered for a wide range of applications from street and towing to marine and race. The kits feature pistons cast from 390 hypereutectic alloy heat-treated to T-6 standards to make them stronger. The pistons also feature fully machined crowns and valve pockets. KB hypereutectic pistons come in several head designs, as well as standard and oversized bore sizes. All KB Hyper pistons are lightweight to improve throttle response and rpm changes, while still being strong enough to withstand high compression and high temperatures. KB Performance Hyper kits (KT) are completed with piston ring sets containing top rings of moly-coated cast iron (M) or ductile iron (D).
