TAMIYA TT01 Rear Hub/Knuckle Arm Performance Upgrade - JR-TT102-BK by Jazrider  [JR-TT102-BK]

Upgraded Rear Hub & Knuckle for TT01 Line

The JR-TT102-BK aluminum rear hub and knuckle arm is an aftermarket replacement created for TAMIYA TT01, TT01E and TT01ED platforms. Replacing the factory plastic hub carriers, the alloy unit gives a firmer mounting for the rear drives and steering linkages to reduce unwanted flex during aggressive driving.

Fitment is limited to the listed TAMIYA TT01 variants, so confirm your chassis type before purchase. The machined aluminum improves durability where the stock plastic can deform, while retaining the original attachment layout so wheel hexes and driveshafts align as designed.

Installation steps include removing the original rear hub carriers, transferring any bearings or set screws, then bolting the aluminum carrier into place. After installation, inspect driveshaft engagement, wheel runout and steering linkage clearance across the suspension travel. The part raises rear stiffness and alters dynamic toe response without changing pickup geometry.

For routine care, check mating surfaces and wheel bearings often and replace worn bearings to maintain proper fit and performance. This is intended only for RC model use and not for real vehicles.
