Underbody gearbox support for TRX4

This aluminium lower gear box mount is made as a replacement hop-up for the TRAXXAS TRX4 Trail Crawler, intended to protect the central transmission area while supporting nearby components. It serves as a structural underbrace that controls gearbox movement and steadies the chassis during crawling.

The primary function is protection and stability: by giving a firm lower attachment it reduces flex around the centre transmission, keeps suspension link geometry more consistent and assists with predictable handling when tuning or carrying heavier loads on technical trails. Robust material choice and firm mounting points influence long term performance and fit.

Parts are very nice. Fit very well. Easy to install. But screws are sometimes to short. And piece was not drilled and tapped deep enough. But overall excellent workmanship. Your shipping leaves a lot to be desired. And it seems tha you got a little confus

Is this a direct bolt-on for TRX4?

The part is designed for TRAXXAS TRX4 Trail Crawler mounting points, but verify your chassis variant and test fit before tightening fully.

What is the benefit of aluminium here?

Aluminium offers a rigid underbrace that resists flex while keeping weight sensible for trail performance.

Will I need different screws?

No, the supplied stainless steel screws in the package contents are intended for the included mount and typical TRX4 holes.

Maintenance advice?

Inspect mounting screws after rough runs, retorque if needed and check for any contact with drivetrain components.
