Yokomo B-MAX2 Rear Bulkhead Upgrade 7075 Aluminium - Arrowmax AM-MAX2-021  [AM-MAX2-021]

Aluminium rear bulkhead with machined sway bar mount

This Arrowmax AM-MAX2-021 Rear Bulkhead Set is machined from 7075-T6 aluminium with a blue anodized finish and is intended as a replacement for the Yokomo B-MAX2 plastic rear bulkhead. The component integrates a machined sway bar mount to stiffen the rear subassembly while maintaining the original chassis geometry.

On-track impact: installing the aluminium unit reduces flex at the mounting area and gives the sway bar a fixed attachment point, which can tighten rear response and make roll-rate changes easier to dial in during setup work.

Fitting notes: the part is designed as a direct swap for the factory plastic bulkhead and lines up with the same fastener positions on the B-MAX2. Verify fastener torque and check clearance after installation, and recheck sway bar linkage geometry to preserve intended handling balance.

For racers and setup technicians using the Yokomo B-MAX2, the Arrowmax aluminium rear bulkhead offers a durable alternative to the stock plastic part and a built-in sway bar mount to support tighter, more predictable rear tuning without changing core chassis layout.
