Tamiya TT01 Rear Knuckle Arm with Collars TT022 Performance Upgrade by GPM  [TT022]

TT01 Rear Knuckle Arm Details

This alloy rear knuckle arm with collars is an aftermarket replacement for the Tamiya TT01 chassis, listed as part TT022. It substitutes the stock knuckle to provide a more rigid mounting for rear hubs and collars while retaining the original TT01 mounting pattern.

In use the arm serves as part of the rear suspension linkage, keeping wheel alignment and axle positioning stable under various loads. The included collars locate the hub and set correct axle spacing to support repeatable handling and easier setup changes.

Fitting is straightforward and follows standard TT01 rear knuckle replacement practice: remove the original item, transfer hubs, pins and fittings, then install the replacement. Check mating surfaces and fasteners for wear and confirm wheel alignment and free rotation after installation.
