Heavy-duty 6061 aluminium lower cover for TRX-4

This scale lower cover is built for Traxxas TRX-4 models to shield the centre transmission and provide a rigid under-chassis mounting surface. Fabricated from 6061 aluminium with a hollowed CNC-machined profile, the design reduces mass while allowing the exposed metal to shed heat.

Fitting the cover helps stabilise suspension links and the lower chassis rail by reinforcing the transmission area and resisting flex during technical low-speed crawling. This product is for model RC use only and not intended for any full-size application.

The package includes replacement fasteners sized for direct installation to the standard lower transmission mount points on compatible TRX-4 models.

  • Transmission Case Lower Cover - 1 pcs
  • Stainless Steel Round Head Screw 3x25 - 2 pcs
  • Stainless Steel Round Head Screw 3x16 - 4 pcs
  • Stainless Steel Round Head Screw 3x10 - 4 pcs
  • Stainless Steel Round Head Screw 3x8 - 2 pcs

Compatible Models

  • Traxxas TRX-4 Defender
  • TRX-4 Tactical Unit

Ideal for trail rigs where transmission protection, increased chassis rigidity and passive cooling matter; included hardware supports a direct swap on the listed TRX-4 models.

Can I use this on other TRX-4 kits?

It is designed for the Defender and Tactical Unit listed in the compatibility box. If another TRX-4 shares the same lower mount layout it may fit, but confirm before fitting.

How does the hollow profile help performance?

The hollowed CNC profile reduces weight while keeping rigidity, and the exposed aluminium surface assists passive heat dissipation from the transmission area.

Does the kit include all screws?

Yes. The kit ships with stainless steel screws in the exact sizes listed so the cover can be mounted using the existing attachment points.

Will the cover need regular maintenance?

Inspect fasteners after initial runs and check for debris buildup. The aluminium surface is low maintenance but clean it if mud or grit accumulates to maintain cooling and fitment.
