KYOSHO V One RRR Rear Bulkhead Cover Racing Replacement V3R-020 by 3Racing  [V3R-020]

Technical rear bulkhead for V One chassis

This rear bulkhead cover is an RC-scale replacement part made for KYOSHO V One RRR, V One SIII, and V One RRR Evo chassis. It is engineered to locate and protect the gearbox area and rear suspension mounts, preserving alignment under load and reducing intrusion of track debris.

Targeted at racers and tuners running hobby-grade touring cars, the part offers direct fitment to the original chassis mounting points so no chassis modification is required for compatible models. It provides a straightforward service spare when the OEM cover is worn or damaged.

Installation notes: separate the rear chassis section to access the bulkhead, transfer bearings and internals from the service part as needed, then secure the replacement using the existing screw points. After fitting, inspect drivetrain alignment and rear suspension geometry to ensure predictable handling and minimise drivetrain bind.

From a setup viewpoint, the bulkhead is a structural component; while changes in material stiffness or mass have limited tuning impact compared with suspension adjustments, a precisely fitting bulkhead maintains consistent rear pivot locations and repeatable handling during competition use.
