6061 aluminium skid plate for TRX-4 transmissions

This scale lower gear skid is made for Traxxas TRX-4 chassis to protect the centre transmission and give a solid mounting surface beneath the frame. Cut from 6061 aluminium with a hollow CNC profile, the part keeps weight down while exposing metal to help passive cooling.

The plate stiffens the lower chassis rail and supports suspension link mounts, reducing deflection during slow rock crawling. Intended for radio controlled vehicles only, not for full-size use.

Included hardware allows direct replacement of the standard lower transmission cover and secures the unit to the existing mounting points on compatible TRX-4 variants.

  • 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

Best suited for trail and crawler setups where extra transmission protection, improved chassis stiffness and passive heat dissipation are required; the supplied fasteners support a simple swap on the listed models.

Will this mount to stock TRX-4 points?

Yes. The fasteners included are sized to replace the factory lower cover and secure to the original mounting points on the listed TRX-4 models.

Is the material corrosion resistant?

6061 aluminium resists corrosion better than mild steel, and the stainless fasteners help prevent rust in typical hobby use. Rinse and dry after salt exposure to extend life.

Does the cover affect ground clearance?

The cover sits under the chassis and will change the lowest point slightly depending on mounting. Check clearance on your specific build and adjust skid or bump stops if needed.

How should I maintain the cover?

Inspect and re-torque screws after initial runs, and clear any packed mud or grit to keep cooling surfaces effective and ensure fastener security.
