Keith Black Dome Top Piston Kit are manufactured from high-strength, T-5, heat-treated, 390 hypereutectic aluminum alloy
Features:
- Allow 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 and pin lock rings available separately
- Compression Ratio: 9.0:1
- Piston Material: T-5, heat-treated, 390 hypereutectic aluminum alloy
Note: 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.
Note: 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.
