Lower gearbox protection for TRX4

This aluminium lower gear box mount is an RC-scale replacement and upgrade for the TRAXXAS TRX4 Trail Crawler platform, built to shield the centre transmission area and give extra support to surrounding parts. The mount acts as a stiff underbrace to limit gearbox movement and stabilise the chassis when tackling technical trail terrain.

As a protective and stabilising component it provides a rigid lower attachment that reduces flex around the central transmission, helps preserve suspension link geometry and makes handling more predictable while tuning or carrying loads. Material choice and secure fastenings determine long term durability and fitment.

  • Stainless Steel Round Head Screw 3x16 - 4pcs

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

Which TRX4 models will accept this mount?

This mount is specified for TRAXXAS TRX4 Trail Crawler platforms; check fitment against your chassis rails and mounting points before installation.

Do the supplied screws match stock locations?

Yes, the kit includes the stainless steel screws listed in the package contents to use with standard TRX4 mounting holes.

Will this change handling on rocks and steep climbs?

By stiffening the lower chassis around the gearbox it can reduce unwanted flex, helping suspension geometry stay consistent under load and improving predictability on technical lines.

Any special install tips?

Hand-start all screws, check alignment before final torque, and verify clearance to driveshafts and links after fitting.
