S&S Cycle 07-17 BT 106in Big Bore Cylinder Kit - Silver

This bolt-on big bore cylinder and piston kit will increase the displacement of 96" or 103" engines to 106". It is as easy as a stock top end rebuild and requires no machining or flywheel rebalancing. For best performance, appropriate camshafts, performance air cleaner, performance exhaust and fuel system tuning are required.
