The Kyosho W5312-02 DC13 Shock Collar is designed as a genuine spare for the Ultima RB7.5. It gives you accurate control over shock preload and spring sit, which helps refine balance and traction across different surfaces. Manufactured to hold up under frequent running, the collar supports repeatable setups so you can reproduce your best settings. A straightforward upgrade for hobbyists who want predictable damper behaviour session after session.
