Tamiya M-05 Aluminium Rear RC Upright - 54178

The Tamiya 54178 aluminium rear upright is a precision-machined hop-up part designed as a direct-fit upgrade for the Tamiya M-05 chassis. Cast from aluminium alloy and finished in a natural silver tone, TAM54178 replaces the standard plastic rear upright with a more rigid component, making it a popular choice for M-05 owners who want to tighten up rear suspension geometry and reduce flex during cornering. Whether you're running touring car bodies on an indoor circuit or pushing the M-05 harder in club racing, the added stiffness of an aluminium upright can help maintain more consistent rear-end feel.
