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

Alloy rear knuckle arm for TL-01

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

The component is designed as a direct-fit upgrade for TL-01 chassis variants using the standard rear hub geometry. Installation removes the original rear knuckle arm assemblies while keeping existing wheel hubs and drive components where they fit, and the supplied collars help preserve correct axle spacing and camber relationships.

From a tuning point of view the alloy knuckle arm increases stiffness at the rear hub pivot, which can lower flex under load and deliver a firmer rear feel when combined with standard TL-01 suspension settings. Fitters should verify alignment and wheel-bearing seating after installation and confirm full free rotation of the axle before use.

This TL1022 set provides a direct-replacement aluminum rear knuckle arm for TL-01 racers seeking a stiffer rear hub assembly and an uncomplicated hardware upgrade path.
