Description
If you’re running a Shovelhead motor, the pinion gear is critical to reliable power delivery and driveline integrity. A worn or damaged pinion gear will compromise acceleration, increase drivetrain wear, and potentially leave you stranded. The S&S Cycle 33-4125 is a purpose-built replacement that restores OEM-spec performance and durability to your big twin.
This pinion gear is engineered to exact tolerances, ensuring smooth meshing with your primary drive and consistent torque transfer. Whether you’re refreshing a stock rebuild or maintaining a high-mileage engine, this is the kind of foundational part you don’t cut corners on.
