Features

PROX Valve Stem Seals - Manufacturer part number: 35.VS028

Designed for motocross riders and mechanical enthusiasts, these PROX valve stem seals ensure a tight seal around the valve stems to limit oil leaks and maintain the proper functioning of the top end. Manufactured by recognized OEM factories in Japan (NOK, ARS), they are made from quality materials and comply with original specifications and tolerances.

Compatibility: intended for MX, Dirtbike, Roadbike, and ATV segments. Suitable for recent models such as KTM 350 SX-F (2025), HUSQVARNA FC 350 (2025), and GAS GAS MC 250 F (2025) according to parts assignment.
Materials and manufacturing: OEM production, premium materials to limit friction and ensure durability over time.
Practical advantage: help maintain the sealing of the guides and reduce the fouling of the valve seats, facilitating engine maintenance.

For any revision or replacement of valve stem seals, choose an original PROX part to maintain manufacturer specifications and ensure a thorough engine restoration.
