Team Associated ASC32080 Shock Collar O-Ring

These 13x15x1mm shock collar O-rings sit between the threaded spring collar and the shock body on your Team Associated RC10TC8. Their job is to add just enough friction that the collar stays exactly where you set it, so your preload and ride height hold through a full run instead of drifting as the suspension cycles.

It is a small part with an outsized effect on consistency. When these O-rings flatten, harden, or wear thin, collars begin to creep under load and the car quietly loses ride height on one corner, which shows up as a chassis that no longer feels balanced from left to right and a setup you cannot reproduce between race days.

Replacing them is quick and does not require a full shock rebuild. Fits the TC8 Graphite-Spec chassis as a direct replacement for the stock O-rings, sliding onto your existing shock bodies under the spring collars. Keep a set in the pit box and change them whenever you notice a collar turning too easily by hand.
