18. In addition to the light weight, the 1-ton axleshafts, the high pinion, and the strong gears, the Hi 9/Spider-9 axles also have great steering angles when outfitted with their Ultimate 60 knuckles. The combination of Spidertrax axleshafts and knuckles results in an amazing 50 degrees of steering, while the average Dana 60 is lucky to reach 45. Plus Spidertrax offers an astronomical Ultimate 1550 knuckle that uses big 1550 steering U-joints to reach an unheard-of 60 degrees of steering. Of course this much steering angle can be dangerous on the street, and nearly impossible to utilize with a standard 4x4 frame since the tires will be hitting the suspension at full lock, but if you're building a buggy it should definitely be considered.
