- Manufactured from high-strength, T-5 heat-treated, 390 hypereutectic aluminum alloy
- Allows a tighter fit and longer piston and ring life

- Each kit contains two pistons, pins, spiral-lock pin clips and Hastings moly rings
- Replacement piston rings sold separately
- KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance.
- Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.
