Centre front shaft technical summary

This centre/front drive shaft is an aftermarket replacement intended for the TRAXXAS UNLIMITED DESERT RACER and is identified by part number UDR037SF.

Precision-machined in hardened steel #45 with a marginally increased diameter versus the OEM shaft, the component improves bending stiffness and reduces torsional deflection within the front drivetrain while remaining compatible with hobby-level loads.

Functionally it transmits torque from the front gearbox to the differential and wheels, contributing to a steadier drivetrain response under load and aiding predictable behaviour during tuning of gearing, motor selection and suspension settings.

Installation requires front gearbox access; the shaft locates in the standard centre front output and is secured with the supplied M4x2.5x13 screw. Typical hand tools used for gearbox work are sufficient.

Packing includes

  • Center Front Drive Shaft - 1pcs
  • M4x2.5x13 Screw Shaft - 1pcs

Specifications

  • Item Center front drive shaft, 2pcs set
  • Material Hardened steel #45
  • Model Number UDR037SF
  • Compatibility TRAXXAS UNLIMITED DESERT RACER

Recommended for replacing worn centre front components or where modest increases in drivetrain rigidity are desired; verify alignment and torque to standard hobby values prior to operation.

Just received Avery well packed and vey shiny box of GPM parts... all look great... only one negative... and probably on my part... the discs and calipers come in sets of 4... not 4 discs or 4 calipers.. oh well another order to follow... great service th

What advantages does the larger diameter deliver?

The slightly increased diameter raises the section modulus, reducing bending under high torque and improving front-end drive stability during load transients.

How is material selection relevant?

Hardened steel #45 offers a favourable balance of hardness and toughness for drivetrain shafts, improving wear resistance while maintaining service life in hobby applications.

Are special alignment checks required?

Ensure the shaft rotates freely with no binding and that gearbox bearings and output faces are correctly aligned before final torque; re-check after initial runs.

What tools are recommended for fitting?

Standard hobby hand tools, a quality hex driver for the supplied screw and basic gearbox servicing tools are sufficient for removal and fitment.
