Description

The United Engine & Machine Co KB906C.010 is a set of forged pistons designed for Twin Cam 88 to 95ci engine conversions. These pistons feature a .010 inch bore size and a 10.5:1 compression ratio.

Constructed from a 4032 alloy with 11% silicon content, they offer excellent resistance to cracking in high-compression applications. The anti-friction skirt coating and a requirement for .001 inch wider piston-to-wall clearance are also noted features. Each kit includes two pistons, rings, wrist pins, and clips.
