Availability:
9 in stock, ready to be shipped
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.
