Description
If you’re looking to unlock genuine performance gains from your Twin Cam engine without the complexity of case-splitting or cylinder boring, the S&S CYCLE Big Bore Kit delivers a straightforward path to increased displacement and power. The bolt-on design lets you swap cylinders in a single afternoon—no machine work required—while the premium aluminum castings with cast-iron liners ensure durability at high RPM.
