The Kyosho UB012 Rear Bulk Head fits the Ultima RB7.5 chassis and is aimed at keeping rear geometry steady during spirited laps. It is a reliable spare for owners focused on consistent handling.
Produced from tough material, this bulk head helps limit chassis movement and maintains component alignment under load. That durability makes it a sensible maintenance choice for frequent track use.
Made to match the Ultima RB7.5 form, the UB012 integrates without trimming or modification, allowing a clean replacement process using standard screws and mounts.
