XV-02 37mm Drive Shafts, RC spare part pair

These 37 mm drive shafts are a dedicated drivetrain upgrade for XV-02 chassis cars and bring the Double Cardan layout into the driveline with a matched pair of shafts. Each shaft carries 2 joints, a configuration described for ground-hugging drive, which helps the chassis keep drive transfer connected through changing suspension angles. The 37 marking on each shaft identifies the specified length at a glance during setup or maintenance. The set contains 2 drive shafts and matches the size of the 37 mm universal drive shaft, making it a focused choice when a build calls for this exact format. As part of the Hop-Up Option Series, these shafts suit replacement work, driveline servicing and chassis-specific tuning on compatible XV-02 cars. The listed companion parts are axle shafts, joint casings, cross joints and 1050 ball bearings, which shows the intended Double Cardan component system around the shafts. On the bench, the pair supports precise rebuilds where matching left and right driveline parts matter. In running sessions on an XV-02 chassis, the Double Cardan joint structure is aimed at keeping drive planted as the car moves across uneven sections and changing grip levels.
