Product Details

This Twin Power kit includes a one-piece starter jackshaft designed to replace the stock Harley-Davidson part number 33216-90. It's built for 1989 through 1993 Big Twin motorcycles, covering a range of popular models like the Electra Glide, Heritage Softail, and Dyna Wide Glide.

The one-piece design is a notable improvement over stock assemblies. It's engineered to transfer more starter torque directly to the primary drive, which can help with starting your engine. Plus, this design is more forgiving when it comes to slight misalignments between components, potentially making installation smoother and reducing stress on related parts. It's a well-built option that often costs less than the original equipment part.
