Precision Aluminium Transmission Spur Case

This four-piece, machined 6061 T6 aluminium transmission spur gear case is a technical aftermarket upgrade for the TRAXXAS TRX4 Trail Crawler. Engineered to replace the OEM plastic housing, it increases structural stiffness and maintains accurate gear mesh during slow-speed crawling and high-load trail moves.

The straight arm geometry minimises deformation under torque while the dual tie rod mounting holes provide discrete setup options to refine steering arc and toe without fabricating new linkages. The design focuses on mechanical stability and chassis tuning rather than altering gear ratio specifications.

  • Material: Aluminum 6061 T6
  • Design features: Straight arm profile, dual holes for tie rod adjustment
  • Included hardware:
    • Stainless Steel Round Head Screws 3*14 - 1 pcs
    • Stainless Steel Flat Head Screws 3*8 - 1 pcs
    • Stainless Steel Cap Head Screws 2.5*6 - 1 pcs

This item is compatible with

  • TRAXXAS TRX4 Defender Trail Crawler

What machining tolerances should I expect?

The case is produced to tight machining tolerances to ensure consistent gear alignment and repeatable fitment with TRAXXAS TRX4 transmission components.

Does the aluminium case require different mounting hardware?

No special hardware is required beyond the supplied stainless screws; use the included 3*14, 3*8 and 2.5*6 fasteners for correct assembly and torque settings.

Should I change maintenance intervals after fitting?

Inspect gear mesh and mounting fasteners after initial break-in and periodically thereafter. The aluminium case improves rigidity but routine checks of mesh and screw torque are recommended for reliable performance.
