This JAZRIDER aluminum transmission spur gear case cover is a scale RC accessory designed specifically for Axial Racing SCX-10 Honcho and Dingo chassis. Finished in gunmetal, the cover replaces the stock plastic surface around the spur gear area to provide a stiffer mounting plane and more consistent spur gear alignment under load.
Intended role and fit: the part supports the spur gear and the adjacent gearbox interface, helping maintain correct mesh during low-speed crawling and technical trail driving. It uses the vehicle's original mounting points and hardware, so installation restores the same attachment geometry while changing the material and surface stiffness.
Installation and tuning considerations: when fitted, expect a firmer gearbox top surface that can reduce micro-movement of the spur gear under torque. This can translate to smoother gear engagement and marginally reduced gear wear if the existing mesh is correctly set. Keep gear backlash and pinion/spur alignment within the chassis' recommended tolerances; the cover is a passive structural upgrade rather than an adjustment component.
Choose this cover when you want a metal replacement that preserves factory fit while offering a stiffer mounting area for the spur gear and gearbox on SCX-10 Honcho and Dingo builds.
