The Kyosho LA392 Rear Upper Bulk is built to strengthen the LAZER ZX7 frame, cutting down chassis flex and giving a firmer platform for precise steering input. The part installs cleanly and is aimed at drivers pushing hard on mixed surfaces.
Engineered to match the LAZER ZX7 mounting points, this rear upper bulkhead slots into place with minimal fuss. Its rugged construction resists deformation so it holds geometry even after repeated heavy use.
With reduced rear flex, the Kyosho LA392 helps the LAZER ZX7 respond more directly to throttle and steering changes, aiding control through turns and on fast straight sections. It is an effective upgrade for drivers wanting more consistent behaviour.
