The S&S Cycle High-Quality Tappet Roller Kit delivers the durability and dimensional consistency required for sustained high-RPM operation, whether you’re building a street cruiser or a dedicated race engine. This is a straightforward bolt-on upgrade that restores proper valve actuation without requiring machine work.
