Keith Black KB348.005 95 in Twin Cam Piston Set .005 Oversize

Keith Black piston set is .005 oversize and is for a 3.875 inch bore. Piston set has a compression ratio of 9.3:1 and includes rings.

The Keith Black KB348.005 95 in Twin Cam Piston Set features hypereutectic alloy pistons cast in a permanent steel mold. This construction supports a lightweight piston design intended to make more power, use less fuel, and provide extended service life. The pistons are .005 oversize for a 3.875-inch bore and provide a 9.3:1 compression ratio.

The alloy's low heat transfer helps keep the skirts cooler for minimal piston expansion. Combined with high compression ring placement, this design is intended to support power and fuel economy. The high ring placement also helps reduce detonation and increase top ring temperature. This set is identified by brand and part number as Keith Black KB348.005.

For proper break-in, run the engine at moderate speeds for at least 500 miles and avoid excessive operation in lower gears. Refer to the Keith Black Sym-Asym Piston Installation Guide for installation instructions. The unit of measure is set, and the country of origin is Mexico.
