XV-02 PRO 39mm double-section CVD upgrade XV2039SC by GPM  [XV2039SC]

Technical overview of 39mm two-piece CVD

The 39mm double-section CVD is an aftermarket 1/10 replacement designed for TAMIYA XV-series drivetrains and supplied under part number XV2039SC. Finished from 4140 carbon steel, the two-section constant-velocity assembly provides a compact joint geometry to preserve torque transfer and resist wear under repeated torque cycles typical in hobby RC use.

Contents: two 39mm double-section CVDs and two M4 lock nuts, recorded as 2 pcs per item. Components are nominally machined to fit the outer drive cups used on the XV-02 and XV01 chassis; verify axle length and joint travel before installation. The original factory unit was 37mm, and full travel compatibility requires pairing these with 39mm dog bones.

For drivetrain servicing, replace fatigued dog-bone elements with these steel two-piece CVDs, confirm drive cup clearance, and secure the supplied M4 lock nuts to maintain correct preload. This is a direct aftermarket drivetrain component for the listed TAMIYA platforms.
