These pistons are a great value, top quality and a great compromise between factory cast and forged. I have ran multiple sets with terrific results.

Important Product Notes

Note: Keith Black pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instruction included with piston for correct piston clearance.

Note: Due to thermal conductivity and design, special attention is required to the top ring end gap. Please read instruction furnished with piston for correct ring installation.
