Athena Valve Stem Seal Kit P400485420602
Athena's valve stem seal kits for offroad applications are engineered to deliver maximum sealing performance in the harshest environments-mud, sand, dust, and high heat. Designed for motocross, enduro, ATV, and UTV engines, these kits offer a professional-grade solution for engine maintenance and rebuilds.
10-piece kits for maximum coverage and flexibility
Each kit includes 10 valve stem seals, a practical quantity that suits most offroad engine configurations. In some cases, the kit will match the exact number required; in others, it may provide extras or require a second kit. This approach ensures broad compatibility and simplifies inventory management for workshops and race teams.
High-quality materials for long-lasting performance
Athena seals are made from premium materials designed to withstand thermal stress, high pressure, and contamination. Their construction ensures consistent sealing over time, helping to prevent oil leaks and maintain engine efficiency even after extended use in demanding conditions.
Developed with top-level racing experience
Athena works closely with elite teams in MXGP, AMA Supercross, Pro Motocross, and EnduroGP. Insights gathered from real-world racing are directly applied to product development, resulting in components that are tested on track and optimized for everyday offroad use.
