The hot axle setup for many of the later-model buggies is custom-built front and rear 14-bolt steering axles. The 14-bolt is highly desirable due to its extra support bearings, which keep the pinions from “walking,” a problem with the high-pinion Dana 60. Many of the custom 14-bolts are also fitted with heavy-duty RCV axleshafts that help keep up the joint strength at all angles. Cole Worx has a few custom tricks to make these axles survive off-road. For example, custom brass bushings are machined into the tubes to support the shafts. Also, a propriety knuckle gusset bolts to the Solid Axle Industries high-steer arm to add support.
