United Engine & Machine’s new KB Super Duty piston series for Harley Twin Cams features Line2Line Abradable Coating as standard on every piston in the new line. Line2Line is applied the thickness of the piston-to-wall clearance for a zero install clearance. The coating abrades in on start-up to hone for the perfect fit per cylinder, and eliminates piston rock for the best possible ring seal with no piston slap noise.

The new series’ hard anodized crown aids in heat deflection and corrosion from alcohol fuels. The top ring groove hard anodizing eliminates micro-welding of the ring to the groove and maintains a flat and smooth surface for best ring seal and less carbon buildup on the dome. The piston’s dome shape accepts Bathtub 85cc or TearDrop 95cc heads.

Complete kits Include pistons, rings, pins and locks, and are available for a variety of big cubic inch engine applications. All applications use standard 4.937″ cylinder length.
