Rear Aluminum Knuckles for TAMIYA TL-01 GF-01 WR-02 - JR-TL105-BK (Black) by Jazrider  [JR-TL105-BK]

Tuning impact of aluminum rear knuckles

This black aluminum rear knuckle set is an aftermarket metal upgrade for the rear steering/knuckle assembly on compatible TAMIYA chassis. As a replacement for the stock plastic components on the named models, it provides a firmer hub mounting surface and a more rigid attachment for rear suspension links, which can change handling character compared with original parts.

Only the chassis noted in the product title are supported: TL-01, GF-01, and WR-02. Check your model's chassis code before ordering; the title retains the exact codes to help confirm compatibility.

Handling and setup notes: installing aluminum rear knuckles will affect rear steering geometry and suspension behavior. After fitting, inspect bearing seating and linkage clearance and monitor any toe or camber shifts. Re-tune suspension settings and toe to harness the altered feedback and achieve the handling balance you want.

Performance perspective: upgrading to aluminum knuckles is commonly used to create crisper rear response and a consistent bearing platform. Expect differences in on-track feel and adapt shock and toe settings rather than assuming a direct swap will produce identical handling.
