Precision CNC aluminium outer case for TRX4 centre transmission

This 4pcs aluminium centre transmission outer case is designed for the TRAXXAS TRX4 TRAIL CRAWLER platform as a direct aftermarket replacement to increase chassis stiffness and accurately locate centre transmission components.

The kit includes stainless steel cup-head screws 2.5x8, 3 pcs. Each machined shell is produced to tight tolerances so bearing bores and shaft seats are repeatable, helping to minimise axial and radial play and improving gear engagement stability.

Technical purpose: retain bearings and axle seats inside the centre transmission housing, maintain consistent bearing pocket geometry, and provide a rigid mounting face to support steady gear mesh during low speed crawling and setup changes. Offered with a 3D cut finish and multiple finish options.

What hardware is supplied?

Four aluminium outer case components plus three stainless steel cup-head screws 2.5x8, 3 pcs.

How do the shells affect tolerances?

CNC machining ensures repeatable bearing seat placement, which reduces runout and helps maintain consistent gear mesh across the centre transmission assembly.

Recommended installation procedure?

Disassemble the centre transmission, verify bearing orientation, trial-fit the shells, torque the screws evenly and check gear mesh under light load before full operation.
