Awesomatix OR1005V - Progression Valve O-Ring (4)

These Awesomatix OR1005V progression valve O-rings are precision molded seals designed specifically for the damper progression valve system found in Awesomatix touring car chassis. Each pack contains four O-rings, giving you enough for a complete rebuild or multiple maintenance cycles depending on your racing schedule.

The progression valve is one of the most critical tuning points on your Awesomatix chassis because it controls how the damper responds through its stroke. When these O-rings wear or lose their elasticity, you'll notice inconsistent damping feel and unpredictable handling transitions. Fresh O-rings restore the crisp, linear damper action that makes Awesomatix suspension so effective on high grip surfaces.

These are genuine Awesomatix replacement parts manufactured to the same specifications as the O-rings that came with your chassis. The material compound is formulated to resist silicone shock oil while maintaining consistent sealing pressure across a wide temperature range. Whether you're running a quick club race or a full weekend national event, these O-rings maintain their shape and sealing properties.

Most racers replace progression valve O-rings every three to four race weekends or whenever damper action starts feeling vague. Keeping a spare pack in your pit box means you can refresh your dampers between qualifiers if needed. It's a small part that makes a measurable difference in how your car puts power down and carries speed through technical sections.

Whether you're building a new Awesomatix chassis or replacing a worn component, the ST01 integrates perfectly with your existing drivetrain. Regular inspection and replacement of axles is part of smart race preparation, ensuring your car performs at its peak when it matters most.
