Description
If you’re building a vintage-correct big-twin engine with modern reliability, this S&S Cycle transmission side cover delivers the aesthetic authenticity you want without compromising on engineering. The factory-inspired casting imperfections pair with internal reinforcements that eliminate the weak points of original designs—particularly around the kicker boss and outer bearing, where dry seizing used to be inevitable. You get a bolt-on cover that accepts stock hardware, ships with a gasket, and keeps your engine looking period-correct while running stronger.
