TAMIYA M04M Graphite Upper Bumper by 3Racing M04M-09/WO  [M04M-09/WO]

Graphite upper bumper overview

This is a graphite upper bumper designed for the TAMIYA M04M 1/10 on-road chassis, supplied by 3Racing as part number M04M-09/WO. The part is an RC-scale hop-up intended to replace the standard upper bumper section to alter front-end stiffness and the mounting interface for body or brace components.

Fitment and role: the bumper is sized for the M04M layout and serves primarily to stiffen the front assembly, which can refine steering response and chassis feedback during tuning. It is a lightweight graphite piece intended for hobby-grade model use only.

Installation notes: the bumper mounts using the stock upper bumper screw points on M04M-style assemblies; basic hand tools and access to original mounting hardware are typically sufficient. When installing, check alignment with the body mounts and confirm no interference with steering linkages or servo horns. Small trimming or shimming of the body or brace may be needed to achieve proper clearance depending on your setup.

Maintenance and tuning tips: graphite provides a balance of stiffness and low weight, so inspect mating surfaces for wear and ensure fasteners remain tight after initial runs. Use the part to experiment with front-end stiffness changes in combination with changes to suspension or tyre setup to evaluate handling differences.
