ProX Countershaft Seal Kit KTM Bearings & Seals

The ProX Countershaft Seal Kit (also called a countershaft oil seal kit or gearbox output shaft seal kit) is a complete replacement for the oil seal behind the front sprocket. This seal sits on a heavily loaded shaft and is constantly exposed to dirt and water, so it can start to leak over time. Checking it whenever you change the front sprocket is good practice.

Key Features:

• Complete kit developed as an upgraded replacement for the OEM parts
• Upgraded oil seal for better durability
• Hardened steel bushing
• O-ring, snap ring or lock washer included where applicable to the application

ProX builds a wide range of countershaft seal kits for dirt bikes and ATVs. Each kit gives you the parts you need to restore a leak-free countershaft seal and improve durability over the original parts.
