About This Product
If your hydraulic clutch is starting to feel soft or you've spotted a leak at the end cover, this rebuild kit is the professional fix. It is designed for 9/16-inch bore master cylinders and fits a wide range of Big Twins, including 1987–2006 Softail and Touring models, as well as 1991–2005 Dyna models. The kit includes a high-quality replacement piston and a set of Viton and Buna O-rings, which are chosen for their excellent resistance to heat and chemicals. This is a direct replacement for OEM 921555, ensuring a perfect fit and restoring the hydraulic integrity of your transmission end cover. It is a must-have for maintaining consistent clutch performance on older hydraulic-equipped Harley-Davidsons. Sold as a kit.
Manufacturer part number: 921555.
