Precision front CVD for TRX4 applications

This front constant velocity drive is a drivetrain component built to transmit torque from the gearbox to the front wheels on a TRAXXAS TRX4 Trail Crawler chassis. The CVDs are CNC-friendly in concept and produced from hardened steel #45 with nutrifying and heat-treatment steps to increase surface hardness and resistance to wear under crawling loads.

Operationally the CVD maintains smooth rotational transfer and stable torque delivery during low-speed, technical crawling. Supplied as a two-piece front set, the components preserve original dimensions for direct replacement where TRX4 front CVDs are specified.

Technical installation notes: replace on a like-for-like basis, verify full spline engagement and correct axle retention torque, avoid excessive fastener preload which can induce joint stress, and confirm no interference with suspension travel. For longevity, pair the hardened CVDs with appropriate differential settings and correct wheel offsets to minimise drivetrain strain.

A precision hardened-steel front CVD set intended as a direct-fit upgrade for TRX4 front drivetrain maintenance, improving surface durability during scale crawling operations.

This item is compatible with

  • TRAXXAS TRX4 Defender Trail Crawler
  • TRAXXAS-1/10 TRX-4 BLAZER 82076-4

What tolerances should I check during installation?

Confirm axial play and spline seating to ensure the CVD engages fully without lateral binding; check axle retention torque against your axle hardware specification.

How does the heat-treatment process benefit the part?

Nutrifying and heat-treatment increase surface hardness and wear resistance, reducing the rate of surface fatigue under repeated low-speed torque cycles.

Which measurements are critical for compatibility?

Key dimensions are the long side 71mm and short side 45mm; ensure these match your front axle geometry and that splines align correctly.

Recommended maintenance after fitting?

Inspect spline engagement and fastener torque after initial runs, re-torque to spec if required, and periodically check for wear or play that could indicate component fatigue.
