Traxxas TRX-4 Center Gear Box (Black Aluminum) - JR-TRX423-BK by Jazrider  [JR-TRX423-BK]

Aluminum center gear box tailored for TRX-4 use

Offered under model JR-TRX423-BK, this center gear box is machined from aluminum and finished black. It is intended for Traxxas TRX-4 scale and trail crawler platforms where the center driveline housing is replaced during repairs or upgrades.

The part houses the centre gearset and forms the interface between the transmission output and the TRX-4 front and rear driveshafts. Before installation, verify fitment against your chassis and driveshaft geometry, and employ proper torque settings to avoid damaging bolt threads.

Fitment notes: remove the original plastic housing and move any internal gears, spacers, or bearings your build requires into this housing, maintain recommended gear lash for your TRX-4 gearset, and check alignment after assembly. This item is supplied as an aftermarket hobby component.

This JR-TRX423-BK aluminum center gear box provides a metal alternative to the stock TRX-4 housing; ensure correct assembly and gear adjustment for dependable running.
