S&S Cycle 36-84 BT 3-1/2in Standard 80in HC Forged Pistons
SKU: S0GE 106-5519
Description
Part #: 106-5519
These 3-1/2" standard bore high compression pistons fit 1979-'84 74" HD (R) big twin engines, producing 9:1 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 (R) will fit these pistons to your existing cylinders (when purchasing new cylinders, pistons can be fit to them as an option).
