Precision aluminium front gear housing for TRX4

This aftermarket front gear housing is designed for TRAXXAS TRX4 Trail Crawlers and is supplied as a 15 pcs set without the cover. It serves as a functional replacement intended to increase mechanical stiffness at critical front-end junctions while maintaining correct integration with the TRX4 front drivetrain and link geometry.

Fabricated from 6061-T6 aluminum to deliver a consistent, low-flex mounting surface, the housing reduces unwanted movement where the differential, suspension links and axle mount meet. The kit excludes the cover so the installer should retain the original cover or fit a compatible aftermarket cover to complete the assembly.

Primary objectives are to stabilise the front differential, secure suspension link attachment points, and provide a rigid mounting seat for the front axle link set and C hub. The component is targeted at hobbyists seeking improved structural performance on TRX4 trail and crawler builds.

Packing includes

  • Stainless Steel Cap Head Screw 2.5x14 - 4pcs
  • Stainless Steel Flat Head Screw 2.5x10 - 4pcs
  • Stainless Steel Flat Head Screw 2.5x6 - 6pcs

Specifications

  • Item TRAXXAS TRX4 Aluminum Front Gear Box (Without Cover) - 15 pcs set
  • Material 6061-T6 aluminum

Use this housing where consistent front-end mounting and reduced flex are required on TRX4 crawlers; confirm fastener selection to match your cover and mounting stack.

What material and temper are used?

The housing is 6061-T6 aluminium, selected for its strength-to-weight ratio and predictable machining and mounting characteristics.

Does the kit include all mounting hardware?

The kit includes the stainless screws listed above for primary mounting and link attachment; verify fastener lengths against your original cover and reuse OEM hardware where appropriate.

Are any machining or fitting steps expected?

For standard TRX4 mounting points no additional machining is expected; check part-to-part clearances and test-fit before final assembly to ensure accurate alignment.

What is the intended use case?

The component is intended for hobby trail and crawler use where improved front-end rigidity and repeatable mounting are desirable for handling and durability.
