For Tamiya TT-01 Type-E Steering Knuckle TT01-E37/LB by 3Racing  [TT01-E37/LB]

Replacement knuckle for TT-01 Type-E

This knuckle arm is an aftermarket service part sold as TT01-E37/LB for use on the Tamiya TT-01 Type-E chassis. It is intended as a direct replacement for a worn or damaged steering knuckle and aligns with the Type-E steering mounts for straightforward fitment.

Fitting is typical RC maintenance: remove the wheel and hub, unbolt the existing knuckle from the suspension upright and steering link, then transfer bearings and hardware to the new unit as required. The component uses standard TT-01 Type-E mounting points so no chassis modifications are normally needed when correctly installed.

When setting up steering, this knuckle serves as a structural interface to adjust toe and scrub radius through connected suspension parts; it is a service replacement rather than a standalone performance upgrade. Check alignment, confirm fastener torque, and perform a cautious test run after installation.
