S&S Cycle - ssc106-5513 - 79-84 BT 3-1/2in +.020in 80in LC Forged Pistons

These 3-1/2" +.020" bore pistons fit 1979-'84 80" HD® big twin engines, producing 8:1 compression with stock unmodified cylinder heads.. The modern alloys used in these pistons, coupled with the advanced skirt profiles, allow them to be fit tighter resulting in low engine noise and long engine life. In the past, this could only be achieved with weaker cast pistons. S&S® will fit these pistons to your existing cylinders (when purchasing new cylinders, pistons can be fit to them as an option).

Brief Description: S&S Cycle ssc106-5513 forged pistons are designed for 1979–1984 80-inch Harley-Davidson Big Twin engines. The 3-1/2-inch bore pistons are sized .020 inch oversize and produce 8:1 compression with stock, unmodified cylinder heads.

Key Features & Performance Benefits: Modern piston alloys and advanced skirt profiles allow tighter fitting for reduced engine noise and extended engine life. The forged construction provides a piston solution for applicable 80-inch Big Twin engine builds. S&S Cycle can fit these pistons to existing cylinders, and piston fitting is available as an option when purchasing new cylinders.
