Tamiya TA01 Alloy Rear Knuckle Arm set by GPM TA1022  [TA1022]

TA01 Alloy Rear Knuckle Arm Overview

This alloy rear knuckle arm set is an aftermarket replacement part produced by GPM for the Tamiya TA01 platform. The component is supplied as 1 pr and is intended as a direct-replacement steering/spindle mount for the TA01 rear suspension, offering a stiffer alloy option compared with typical plastic parts.

Use notes focus on fitment and tuning: confirm fit to existing hinge pins and wheel hexes before final installation, check servo linkage geometry after replacement, and verify suspension articulation through its travel to avoid binding. The part serves a tuning role by changing compliance at the rear steering pivot and can affect transient steering feel when paired with adjustments to camber and toe.

For builders and tuners working on 1/10 RC touring cars using the TA01 chassis, this alloy rear knuckle arm offers a straightforward upgrade path to a metal pivot component, useful when targeting consistent steering response and reduced wear over long sessions.
