The Traxxas 7065 (Caps & Spring Retainers) set provides the external shock caps and retainers used when servicing GTR‑style shocks on 1/16 scale models (1/16 E‑Revo, Slash 4WD, Summit, etc.). Pair it with a shock rebuild kit (like the 7062) to fully refresh leaking or worn shocks by replacing internal seals, bladders, pistons and mounting hardware. Rebuilding shocks helps maintain smooth suspension action and extend shock life.
