Muchmore Racing FLEX Shock O Rings were developed by the World Champion Marc Rheinard in collaboration with X-GEAR. These o-rings are compatible with a variety of 1/10th scale on-road and off-road vehicles and are made from a unique silicone compound that is less prone to “swelling” under the influence of silicone shock oil. This creates a better seat of the seals within the shock cartridges over a longer period lead time and a super smooth fitting fitting shock shaft.
The "FLEX O-RING" is available in three ratings and are recommended for specific applications. Muchmore recommends 50 and 60 degree options for Carpet track racing. Low traction surfaces and cold temperatures, 40 degree is recommended. Package includes eight o rings.
