Center gear housing for TRX-4 tuned builds

This center gear box carries the part number JR-TRX423-BK and is finished in black. Constructed from aluminum, it is designed for Traxxas TRX-4 scale and trail crawler platforms where a metal center housing is preferred for service or tuning reasons.

The housing secures the center gearset and creates the mounting points linking the transmission output to the front and rear driveline shafts on the TRX-4. Confirm vehicle geometry and driveshaft alignment before final installation, and tighten fasteners to recommended values to protect threaded holes.

Assembly advice: remove the factory plastic housing, transfer internal components such as gears, spacers and bearings as required, keep the gear mesh within appropriate clearance for your TRX-4 gears, and re-check alignment after you finish assembly. This is supplied as an aftermarket RC accessory.

Fit JR-TRX423-BK when you want an aluminum replacement for the TRX-4 central driveline housing; ensure correct gear setup and alignment for consistent performance.

Will this housing change driveline stiffness?

Switching to an aluminum housing can increase structural stiffness in the central driveline area. Expect a firmer mounting platform for gears, which can affect how loads are transferred through the TRX-4 chassis.

Is any machining required before fitment?

No machining should be needed if the housing is specified for TRX-4. Confirm dimensions against your parts and check that internal gear bearings seat correctly when transferred over.

Does the black finish affect part fitment?

The black finish is cosmetic and does not alter mounting features; verify that any surface coatings do not interfere with bearing seating or mating surfaces during assembly.

How often should I inspect the aluminum housing?

Inspect mounting points and gear mesh periodically, especially after heavy runs. Re-torque fasteners and check for unusual wear as part of regular TRX-4 maintenance.
