S&S CYCLE Replacement Flywheel Assembly — 4-3/8" stroke, A motor – 12-17 Dyna, 09-10, 13-16 Trike, 11 Touring, 07-17 Softail

Fully assembled replacement flywheel engineered for 96"/103"/106" big-bore and 110"/117" engines with stock or S&S pistons.

Includes premium S&S® heavy-duty 7.659" connecting rods with full-width wrist pin ends and a fully dynamic balance to support higher rpm.

Trued to less than .0005" runout on pinion and sprocket shaft bearing surfaces, making it compatible with gear drive cams.

CNC machined from heat-treated, closed-die steel forgings and tested to be 114% stronger than late-style stock flywheels.

The only joints in the assembly are where the 1.671" diameter connecting rod crankpin is pressed into the flywheels; pinion and sprocket shafts are forged as part of the flywheel.

Made in the USA and requires S&S pistons for installation. ⚙️🇺🇸
