This JAZRIDER aluminum rear gear box cover is a direct-fit RC-scale replacement designed for Tamiya TA01, TA02 and DF01 chassis. As a metal top plate for the rear gearbox area, it replaces the original cover to provide a stiffer mounting surface and a durable contact area where the gearbox meets the chassis.
Fitment focuses on the listed Tamiya chassis only. The part is provided in red aluminum and uses the stock mounting points to secure the gearbox assembly. Installation swaps the original cover with the alloy unit and retains factory screw locations and alignment; users should verify gear mesh after installation and confirm all fasteners are seated evenly.
For tuning and setup the cover is intended to reduce flex at the rear mounting interface and to keep gear alignment more consistent under load, which can aid repeatable adjustments to gear mesh and rear-end handling. Routine maintenance access remains possible as the cover follows the chassis' existing removal sequence.
