Right Rear Bulk Head Aluminium for Yokomo YZ-4S - S4-002BRRA  [S4-002BRRA]

Overview of the right rear aluminium bulkhead

A right-side aluminium rear bulk head designed for Yokomo YZ-4S chassis, the S4-002BRRA gives a stiffened mounting point for the rear suspension on 1/10 electric touring cars. It aims to improve repeatability in suspension geometry and support setup accuracy.

Fitted at the right rear position on compatible YZ-4S platforms, this machined, anodized component serves as a more rigid alternative to softer stock parts, keeping alignment true under load and resisting routine wear.

Installation is generally simple: align the part with the chassis mounting locations, secure it with the original fasteners, and confirm there is adequate clearance for the motor, ESC, and rear linkage movement. Treat changes at this junction as part of your setup strategy since they affect rear grip and transient response.

Use the S4-002BRRA when you need a dependable, dimensionally true rear mounting point on YZ-4S cars, and remember routine fastener checks after track use.
