NEW One-Piece Billet Shafts are Now Available! If you drive a wheel directly on a DartBox Drive shaft, this upgrade will be perfect for you! The all new Billet shaft is perfect for maximum durability. This upgrade kit is exactly what you need to swap a 6mm shaft onto your existing DartBox Drive gear motors. The replacement shafts come already pressed into a carrier plate with pins installed for planet gears. The carrier plate is the only part identical to what is originally shipped inside the gearboxes. Gears are not included, you will need to make sure not to lose any parts when disassembling your gearbox to replace the shaft! Here is a video for assembling the 6mm upgrade front plate, and here is a video on replacing the existing shaft. Just follow the same reassembly process as for the original. To upgrade a gearbox, you may need circlip pliers or a small flathead screwdriver, and a 1.5mm hex wrench (the same size included with any of my Motor Mount Plates). No other tools are needed, but blue Loctite (242) is recommended for reinserting the screws. One kit is needed to upgrade one (1) DartBox V2 Drive gearbox. Here is the CAD model for a DartBox Drive with 6mm output shaft. These shafts ARE compatible with original DartBox V1 (not square) gearboxes, and both 23:1 and 107:1 DartBox V2. They also are compatible with Rectified Robotics brushed and brushless 22mm gear motors. But they are NOT compatible with Mega Spark, Botkits, Mercurybox or the V2 135:1 HR gearboxes. The shaft carrier pin spacing is different. I have yet to find out if they are compatible with any gearbox besides those above. Billet shafts will include an extra clip and spacer, but standard will not. If you lost a clip, screw, or another gearbox component, use the Contact Us page to email and request them as we do have a limited supply on hand. Videos
