Tamiya TL-01 Alloy Rear Knuckle Arm with Collars & Screws by GPM TL1022  [TL1022]

Alloy rear knuckle arm for TL-01

This GPM aftermarket rear knuckle arm set is produced for the Tamiya TL-01 platform and supplied under GPM part TL1022. The set replaces the stock plastic rear knuckles with machined aluminum components and includes collars and mounting screws to restore linkage and axle positioning for the rear suspension.

The part is intended as a direct-fit upgrade for TL-01 chassis variants that use the standard rear hub geometry. Installation replaces the original rear knuckle arm assemblies, retaining existing wheel hubs and drive components where applicable, and the collars provided help maintain correct axle spacing and camber relationships.

In tuning terms the alloy knuckle arm increases surface stiffness at the rear hub pivot, which can reduce flex under load and offer a firmer rear feel when combined with standard TL-01 suspension settings. Users should verify alignment and wheel-bearing seating after installation and check for full free rotation of the axle before running.

This GPM TL1022 set offers a direct-replacement aluminum rear knuckle arm for TL-01 racers looking for a stiffer rear hub assembly and a simple hardware upgrade path.
