This aluminium rear hub carrier is engineered as a direct-replacement for Tamiya TT-01 and TT-01 TYPE E rear knuckles, designated TT01-12/0/LB. It provides a stiffer mounting point intended to tighten rear suspension response for competitive setups.
Fitting requires standard TT-01 disassembly: remove the rear knuckle, install the aluminium carrier, and refit existing axle hardware. Maintain original mounting geometry and use common hex tools; ensure bearings are seated correctly to avoid unwanted preload or binding.
On-track, a metal carrier reduces compliance at the knuckle and can sharpen consistency through cornering transitions. Pair this unit with matched bearings and considered wheel offsets when aiming for repeatable lap times and predictable handling adjustments.
