A-Parts Gearbox F/R 58370, RC spare parts

This A-Parts sprue is made for the 58370 and provides black injection-molded components for the gearbox F/R area of the DF-03. The unassembled runner groups housing halves, covers and structural sections in one set, giving repair work a direct route back to the intended drivetrain layout. The molded pieces show reinforced ribs, screw holes and cylindrical shaft or bearing mounts that matter when a transmission case needs its original geometry. A larger frame-like section with elongated slots adds another chassis-facing support element, while rounded shell parts serve as protective case sections around moving drivetrain parts. Because the components are supplied on the sprue, each shape stays clearly separated until preparation begins, which helps with part checking before installation. The glossy black finish matches the technical look of many RC chassis internals. This spare parts set suits maintenance benches, rebuild projects and targeted gearbox repairs where damaged housings, brackets or covers need replacement with matching forms. It also supports keeping a DF-03 running with dedicated structural parts on hand for future service work.
