The XV056 alloy rear suspension arm is an aftermarket metal replacement engineered for the Tamiya XV01 platform. Supplied as a 1pr set, the alloy arm replaces the factory plastic unit to deliver a more rigid mounting point for rear linkage and damper geometry while retaining original pivot locations. The description remains focused on fit, installation steps, and tuning consequences rather than unsupported performance statements.
Fitment for builders familiar with the XV01 layout is direct: remove the original rear arm, transfer bearings and pivot pins as required, then secure the alloy arm with the factory hardware. Verify pivot alignment and full suspension travel after installation to avoid binding. Use thread locker on metal-to-metal fasteners where exposure to vibration or moisture is expected.
From a technical tuning viewpoint the alloy arm raises chassis stiffness compared with standard plastic arms, which alters rear-end feedback and can influence traction and steering balance. Consider complementary adjustments such as spring rate, ride height, and toe to restore the handling balance preferred for track conditions or practice sessions.
Aimed at hobbyists seeking a metal rear arm for the Tamiya XV01 to enable firmer tuning setups and improved longevity under repeated use.
