Product Details
Highlights
- Manufactured from high-strength, T-5 heat-treated, 390 hypereutectic aluminum alloy.
- Allows a tighter fit and longer piston and ring life.
- Diamond-machined pistons are held to plus or minus one gram weight and less than one-half-thousandth-inch (.0005") tolerances from piston to piston.
- 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.
- Kit Includes:.
- 2x Pistons.
- 2x Wrist Pins.
- 4x Spiral Lock Pin Clips.
