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

Alloy rear knuckle arm for TL-01

This GPM aftermarket rear knuckle arm kit is produced for the Tamiya TL-01 platform and offered as part number TL1022. The set replaces the original plastic rear knuckles with machined aluminum components and includes collars plus mounting screws to restore correct linkage and axle placement for the rear suspension.

The item is intended as a direct-fit upgrade for TL-01 chassis variants that share the standard rear hub geometry. Fitting replaces the factory rear knuckle arm assemblies while keeping existing wheel hubs and driveline parts where they are compatible, and the supplied collars help secure proper axle spacing and camber alignment.

In tuning terms the alloy arms increase rear hub pivot stiffness, helping to reduce flex under heavy loads and providing a more solid rear end when used with typical TL-01 suspension setups. After installation check hub alignment, bearing seating and ensure the axle rotates freely before use.

The TL1022 kit gives TL-01 drivers a straightforward aluminum rear knuckle replacement that targets reduced pivot flex and simplified hardware fitting.
