Piston set has a compression of 10.6:1 and includes rings.\n\u003cp\u003eThe Keith Black KB343 .030 88-inch Twin Cam Piston Set features hypereutectic alloy pistons cast in a permanent steel mold. This construction supports a lightweight piston design intended to help produce more power, improve fuel economy, and promote long service life. The pistons are .030 oversize for a 3-3\/4-inch bore and have a 10.6:1 compression ratio.\u003c\/p\u003e\u003cp\u003eThe alloy's low heat transfer helps keep the skirts cooler, minimizing piston expansion. Combined with high compression ring placement, this design is intended to support power and economy. High ring placement also helps reduce detonation and increase top ring temperature.\u003c\/p\u003e\u003cp\u003eNew pistons and rings should be broken in by operating the engine at moderate speeds for at least 500 miles and avoiding excessive operation in lower gears. Refer to the piston fitment instructions for installation guidance. This piston set is listed for 1999–2006 Harley-Davidson FXST models and 1999–2000 Harley-Davidson FLST models.\u003c\/p\u003e\u003cp\u003eBrand: Keith Black. Part number: KB343 .030.
