GPM XV056 Alloy Rear Suspension Arm for Tamiya XV01 chassis, aluminum alloy rear arm upgrade  [XV056]

Alloy rear suspension arm for XV01

This GPM XV056 alloy rear suspension arm is an aftermarket replacement designed for the Tamiya XV01 platform. Supplied as a 1pr set, the component replaces the standard plastic rear arm to provide a firmer mounting point for the rear suspension linkage and shock geometry. The description and wording stick to its role as an RC-scale upgrade, focusing on fit, installation steps, and tuning impact rather than performance claims.

Installation is straightforward for builders familiar with the XV01 layout: remove the stock rear arm assembly, transfer any bearings or pivot pins as required, and secure the alloy arm using the original hardware. Check pin alignment and suspension travel after fitting to confirm there is no binding. Use thread locker on metal-to-metal fasteners if you intend to run the car in humid or high-vibration conditions.

In tuning terms this alloy arm provides increased rigidity compared with common plastic arms, which changes the rear-end feedback and can affect traction and steering balance. When fitting alloy arms consider complementary adjustments such as shock spring rate, ride height, and toe settings to re-establish the handling balance you prefer on track or during practice.

This part is aimed at hobbyists who want a metal replacement for the stock rear arm on the Tamiya XV01 chassis to support more robust tuning and longer-term durability.
