Traxxas TRX-4 Aluminum Rear Gear Box Mounts 6061-T6 TRX4013CA by GPM  [TRX4013CA]

Billet 6061-T6 rear gearbox supports for TRX-4

This aftermarket 28pcs aluminium mount kit is an RC-scale accessory designed to alter the rear gearbox-to-knuckle interface on Traxxas TRX-4 vehicles, providing a firmer mechanical link between the rear gear box and rear knuckle arms while allowing incremental damper position adjustment. The parts are billet-style pieces produced from aluminum 6061 T6 to keep weight low and tensile strength high without implying any full-scale vehicle application.

The kit replaces the stock attachment points with a C-clamp style connection for the rear knuckle arms and relocates damper upper mounts slightly outward compared with the original vertical orientation. That outward offset increases lateral stability and gives room to tune damper height and angle for trail crawling setups.

Hardware included in the supplied kit follows the manufacturer's listing and should be used as supplied for the stated effects on damper position and tie rod stabilization. Note the kit separates tie rod stabilization from damper stabilization when using the longer 3x18 screws that secure tie rods independently of the damper mounting.

Use the supplied collars and the corresponding screw lengths to achieve the intended spacer stack and damper offset, and verify fitment on your chassis before final tightening to avoid binding in the rear suspension linkages.
