TAMIYA TT01/TT01E/TT01ED Rear Knuckle Arm — Aluminum (Red) JR-TT102-RD by Jazrider  [JR-TT102-RD]

Aluminum rear knuckle arm for TT01 variants

This rear knuckle arm and hub assembly is built for TAMIYA TT01, TT01E and TT01ED chassis. The red-anodized aluminum offers a more durable alternative to the original plastic hub, intended to reduce wear at rear suspension attachment points.

Use is restricted to the listed TT01 models. The unit mates with the existing wheel hubs, uprights and fasteners on those cars and does not require modification to the suspension geometry.

To install, remove the factory hub assembly, fit the alloy hub/knuckle arm in the same orientation, and tighten the original fasteners to the recommended torque. After installation check wheel alignment and hub rotation to ensure there is no binding. This component is designed as a straightforward durability or maintenance upgrade rather than a redesign of the chassis.

For hobbyists the part provides consistent mounting for the rear wheel assembly and helps maintain alignment through repeated use.
