TRAXXAS TRX4 Trail Crawler Aluminum Front/Rear Gearbox Bottom Protector Mount by GPM TRX4333  [TRX4333]

Aluminum gearbox bottom protector

This aluminum bottom protector is designed as an RC-scale accessory for the TRAXXAS TRX4 trail crawler platform. It mounts closely to the underside of the front and rear gearboxes to reduce abrasion and direct impacts from sand, gravel and rocks encountered during trail crawling.

The part uses a lightweight aluminum construction to add protection without a significant weight penalty. The design focuses on low profile attachment to keep ground clearance and allow normal suspension travel while guarding vulnerable gearbox surfaces from repeated contact on rough terrain.

Installation is straightforward for hobby technicians: the plate aligns to the gearbox lower surface and secures with the vehicle's underside mounting points. Its role in tuning and setup is protective rather than performance boosting, letting you concentrate on suspension and tire choices while reducing the chance of gearbox damage during aggressive off‑road runs.
