TRAXXAS TRX4 TRAIL CRAWLER Aluminium Center Transmission Outer Case by GPM TRX4038A  [TRX4038A]

Aluminium center transmission outer case for TRX4

This 4pcs aluminium center transmission outer case is produced by GPM for the TRAXXAS TRX4 TRAIL CRAWLER platform and is intended as an RC-scale replacement part to stiffen and precisely locate the center transmission components.

The set includes stainless steel cup-head screws 2.5x8, 3 pcs. The aluminium shells are CNC-cut to tight tolerances to position bearings and shaft seats accurately, which helps the transmission gears run with reduced play and smoother engagement.

Primary roles: secure bearings and axles inside the center transmission box, maintain precise bearing compartments, and provide a firmer mounting surface to aid consistent gear mesh during trail crawling and tuning adjustments. Visual options include a 3D cut pattern for a metallic appearance and multiple colour choices.
