About This Product
Designed for the 103-inch Twin Cam engine, these Drag Specialties replacement pistons are intended for standard bore cylinders. They serve as a direct replacement for factory pistons, helping to restore original power and efficiency during an engine refresh. The aluminum construction ensures proper heat dissipation and weight balance within the rotating assembly. Each kit comes complete with the required rings, wrist pins, and circlips for a comprehensive installation. Drag Specialties provides these components to meet the needs of riders looking for dependable engine parts that follow original equipment dimensions. This product is sold as a pair.
