Tamiya TA01 Alloy Rear Knuckle Arm Upgrade - TA1022 by GPM  [TA1022]

TA01 Rear Knuckle Arm Alloy Upgrade

This alloy rear knuckle arm set is an aftermarket replacement for the Tamiya TA01 platform. The component is supplied as 1 pr and fits as a direct-replacement steering spindle for the TA01 rear suspension, offering a firmer alloy option compared with standard plastic parts.

Fitment and setup notes: confirm hinge pin and wheel hex alignment before final assembly, check servo linkage geometry after installation, and cycle the suspension through travel to ensure there is no binding. As a tuning item it changes rear pivot compliance and can alter transient steering feel when you adjust camber or toe.

For builders and tuners working on 1/10 touring cars based on the TA01 chassis, this alloy knuckle provides a simple metal upgrade to improve repeatable steering response and lower long term wear.
