Upgrade for TAMIYA TT01/TT01E Rear Upper Suspension Arms JR-TT105-LB by Jazrider  [JR-TT105-LB]

Precision rear upper arms for TT01/TT01E

Designed for the TAMIYA TT01 and TT01E, this RC-scale aluminum rear upper suspension arm comes with a light blue anodized finish. It replaces the factory plastic arm to offer a firmer mounting point that supports consistent setup and handling improvements.

Fitting the arm involves removing the rear wheel hub, detaching the original upper arm, and installing the aluminum unit with the vehicle's existing mounting bolts. Confirm ball stud alignment and free suspension movement after installation to avoid binding.

From a tuning perspective, the rear upper arm alters the way the chassis transmits loads to the suspension. A more rigid aluminum arm reduces flex under load and delivers more repeatable response through corners, which helps when dialing rear toe and camber.
