Traxxas now makes it possible to add the strongest, most durable front and rear driveshafts to the Rally, Slash 4X4, and Stampede 4X4. Originally designed for the 100+mph XO-1 Supercar, steel-splined driveshafts with 6mm axles can now be added to your favorite 4WD off-road model. The new Traxxas 12mm aluminum hex adapters feature a 6mm inner diameter to accept the beefier axles. The 12mm hex adapters are easy to install, compatible with Traxxas short course and rally wheels, and will also fit most standard 12mm hex-style wheels. The rugged machined-aluminum construction provides maximum performance, with custom looks coming from the vivid blue-anodized finish. Hex adapters require the following items for installation on Slash 4X4, Rally, and Stampede 4X4 -- #6451 (x2), #6452 (x2), #6439, #6455, #5117 (x3).
