Tamiya XV01 Alloy Rear Suspension Arm Upgrade - XV056 by GPM  [XV056]

Aluminium rear arm upgrade for XV01 chassis

This XV056 alloy rear suspension arm is an aftermarket replacement made to fit the Tamiya XV01 platform. Supplied as a 1pr set, the component swaps the factory plastic arm for a metal unit that gives a firmer anchor for the rear linkage and shock geometry while keeping the stock pivot pattern. The text focuses on correct fit and setup rather than exaggerated performance claims.

Installation is straightforward for those familiar with the XV01 layout: remove the stock rear arm, transfer any bearings or pivot pins as needed, and fasten the alloy arm with the original hardware. After fitting, inspect pin alignment and suspension travel to ensure there is no binding. Apply thread locker to metal-to-metal fasteners if you expect humid conditions or persistent vibration.

From a tuning perspective the alloy arm increases stiffness over common plastic arms, altering rear feedback and potentially changing traction and steering balance. When fitting this arm consider matching changes such as spring rate, ride height, or toe adjustments to re-establish the handling character you prefer for track or practice runs.

This component suits hobbyists seeking a metal replacement for the stock rear arm on the Tamiya XV01 chassis to support heavier tuning and longer-term durability.
