S&S CYCLE - 320-0360 - Flywheel Assembly - 4-3/8” - with Sprocket Bearing Race - Twin Cam ”A” '99-'06 (except '06 Dyna)
The S&S CYCLE 320-0360 is a 4140 steel sprocket built for riders who want OEM-quality tooth geometry and dimensional accuracy without the OEM price point. For 96”/103”/106” big bore | 110”/117” engine with stock or S&S pistons (will be noted), which is what keeps a chain running quietly and without accelerated wear. Fully assembled with premium quaility S&S® heavy duty 7.659” connecting rods, with full width wrist pin ends, and dynamically balanced. Pairing a fresh chain with fresh sprockets is always the right call: a new chain on worn sprockets adapts to worn tooth geometry immediately, shortening both. The 320-0360 gives you a sprocket worth pairing with a quality chain. Sold individually.
