About This Product
This MCS rear caliper seal kit is a staple for any shop working on late Evolution and early Twin Cam era motorcycles. It fits a broad range of models from late 1987 to 1999, including Big Twins, Twin Cams, and XL Sportsters. As a direct replacement for OEM 44045-87 and part number 910491, this kit includes the essential seals to rebuild your rear caliper and stop fluid leaks in their tracks. Rear brakes are often neglected, but keeping the seals fresh is vital for balanced stopping power. This kit offers a reliable, cost-effective solution for maintaining the hydraulic performance of your rear brake system on these classic Harley-Davidson platforms.
