YZ-4S Aluminum Right Rear Bulk Head (Machined) - S4-002BRRA for Yokomo  [S4-002BRRA]

Right rear bulk head: machined aluminum detail

This machined aluminum right rear bulk head is made for the Yokomo YZ-4S chassis; the S4-002BRRA supplies a stiff, accurate mounting point for the rear suspension on 1/10 electric touring cars. It is intended to help maintain consistent suspension geometry under repeated use.

Mounted in the right rear location on compatible YZ-4S platforms, the component replaces softer stock parts with a dimensionally stable metal alternative. The anodized finish and precision machining reduce wear and keep fitment consistent through routine servicing.

Fitment is typically simple: position the bulk head on the chassis mounting bosses, use the existing fasteners to secure it, and double-check clearance around the motor, ESC, and rear linkages. Consider this part part of your setup toolkit—small changes at the bulk head influence rear traction and transient onset.

Opt for this S4-002BRRA when you want a long-lasting, true-to-dimension rear mounting point for YZ-4S chassis work and remember to match left/right parts and check fixings after sessions.
