Team Associated ASC31935 6x6 Extended Gearbox

The Team Associated ASC31935 6x6 extended gearbox housing carries the gears, bearings, and output shafts for the rear drive section of your six-wheel-drive semitruck. Its extended shape positions the second rear axle correctly and keeps the gear mesh aligned so power reaches all four rear tires without binding or excessive noise.

This gearbox is a direct replacement for the RC10 American Custom Semitruck, matching the factory unit exactly and installing with the same screws and hardware called out in the assembly manual. Gearbox housings absorb the shock of rough surfaces and hard landings, and a cracked or flexing case lets the gears skip under load. Fitting a fresh housing restores tight, consistent mesh and protects the gears and bearings inside it.

Builders assembling a second truck or repairing crash damage will find this the fastest route back to full six-wheel drive. Keep one on the bench so a broken case never sidelines your rig, and rebuild with genuine Team Associated components for the fit, strength, and durability the platform was designed around.
