Upgrade your drivetrain seal area with the PROX Countershaft Seal Kit, designed as an improvement over OEM parts to help reduce oil leaks at the countershaft/front sprocket.
Complete kit includes key components for a proper refresh where applicable.
Designed to outperform standard OEM countershaft sealing components, the PROX Countershaft Seal Kit is a smart upgrade when servicing the output/countershaft area—especially if you’ve noticed seepage around the front sprocket or you’re rebuilding for reliability.
By combining an upgraded seal with a hardened bushing, this kit helps improve durability in a high-wear area where dirt, chain debris and constant rotation can quickly compromise sealing performance. The result is a cleaner engine case, less mess around the sprocket, and more confidence on every ride.
