TAMIYA Rear Knuckle Upgrade for TL-01 / GF-01 / WR-02 - JR-TL105-BK (Black) by Jazrider  [JR-TL105-BK]

Fitting the aluminum rear knuckle

This black aluminum rear knuckle set is supplied as an aftermarket metal replacement for the rear steering knuckle assembly on compatible TAMIYA chassis. It replaces the factory plastic parts on the listed models to give a firmer hub mounting point and stronger attachment for rear suspension linkages compared with stock plastic units.

Make sure compatibility matches the title: TL-01, GF-01, and WR-02. Always confirm your chassis code before purchasing to avoid fitment issues; the exact chassis codes are preserved in the product name for clarity.

Installation advice: when installing this part, expect an effect on rear steering geometry and suspension response. Check wheel-bearing seating, linkage clearance, and any changes to toe or camber as you fit the knuckles. Use small, measured adjustments to linkage positions to return the desired geometry after installation.

Practical tuning note: aluminum knuckles often tighten up the rear mounting points and can alter steering feel. Evaluate handling after fitting and adapt suspension settings and toe to suit the new, firmer mounting surface.
