Tamiya M03/M03L/M04M/M06 PRO Rear Hub Carrier 0 Degree M04M-03/0/LB by 3Racing  [M04M-03/0/LB]

Race-focused anodised rear hub carrier

This machined aluminium rear hub carrier is anodised in light blue and built as a direct-fit upgrade for Tamiya M03, M03L, M04M and M06 PRO chassis. The 0 degree specification preserves neutral rear geometry so measured roll center and suspension angles remain consistent when fitted to the stock mounts.

Manufactured as a single-piece machined component, the hub carrier offers improved wear resistance under repeated wheel changes and aggressive track use compared with the stock plastic unit. It retains factory mounting points for simple installation using original hardware and ball studs where applicable.

For racers and tuners the carrier supplies a consistent rear mounting platform that helps isolate setup variables such as spring rates and tyre choice. Because it keeps factory geometry at 0 degree, predictable handling changes will come from altered stiffness and mass rather than alignment shifts.

Service recommendations include regular cleaning of the anodised finish, verification of fastener torque to the chassis maker's specs and use of thread-lock where the original assembly required it. Inspect bearing and mating surfaces for contamination or wear during scheduled maintenance.
