Tamiya TT01 Alloy Front Upper Arm with Delrin Collars - TT054 by GPM  [TT054]

Alloy front upper arm for TT01 chassis

This aftermarket front upper arm is made for the Tamiya TT01 scale touring chassis and is supplied as an alloy unit with Delrin collars. It replaces the stock plastic upper arm while keeping the original mounting geometry, letting you tune handling with a different material set.

The part retains the stock fit points and mounting locations so it swaps into TT01 variants that use the OEM upper arm layout without modification. In use it performs the same suspension link function as the original, with alloy stiffness paired with Delrin collars to limit local wear where pins and studs sit.

Install this arm when you want more predictable camber behaviour and a firmer connection to the steering knuckle, or to replace worn plastic arms during regular maintenance between track or club sessions. This item is for RC model use only and is not suitable for full-size vehicles.
