Tamiya TA01/TA02/DF01/FF01 Aluminum Rear Knuckle Arm by JAZRIDER JR-TA109-LB  [JR-TA109-LB]

Aluminum rear knuckle arm for Tamiya chassis

This aluminum rear knuckle arm is a direct-fit RC-scale replacement for Tamiya TA01, TA02, DF01 and FF01 chassis where the rear steering or hub assembly requires a machined aluminum part. The light blue anodized finish identifies the component visually while the aluminum material improves rigidity compared with common plastic pieces, helping keep steering geometry consistent under load.

Installation is straightforward for users familiar with basic chassis maintenance: remove the original rear knuckle, check mating surfaces and fasteners on the hub carrier, then fit the JAZRIDER aluminum arm in place using the existing hardware. No special tools are required beyond common hex drivers used on Tamiya models; verify thread engagement and torque to avoid stress on surrounding plastic parts.

In tuning and setup the aluminum rear knuckle arm serves two practical roles: it reduces flex in the rear steering link area for a crisper steering response, and it provides a durable spare for frequent track use or club practice where part replacement may be needed. As with any RC part, check alignment and wheel bearing clearance after installation to ensure expected handling on the track or during hobby runs.
