TAMIYA TT01 Touring Rear Upper Arm Alloy TT057 by GPM  [TT057]

Replacement alloy upper arm for TT01

This aluminium rear upper arm is an aftermarket part produced by GPM for the TAMIYA TT01 platform and arrives with shims, collars, E-clips and retaining pins. It replaces the stock plastic arm to provide a more rigid rear mounting point on 1/10 touring cars.

Installation guidance: use the included pin hardware and follow the TT01 rear hub and suspension geometry during fitment. Verify pin seating and clearances around the wheel hub and suspension links, and apply the supplied shims to tweak camber and track where necessary.

Handling benefits: alloy stiffness cuts down unwanted flex in high load situations, helping keep camber and toe settings stable through acceleration and cornering. Collars and shims allow small lateral and pivot adjustments to tune steering balance and tyre wear.
