The kit consists of a series of special tools, including software on CD-ROM with printable worksheets, a digital protractor that automatically displays driveline angle settings, a tube diameter gauge, ...

Most lifted vehicles require the addition of a CV (constant velocity) joint. When a standard U-joint driveline cycles and changes its angle, it actually changes speed to faster and slower.

High-Angle Driveline uses U-joints that are larger than 1-ton—along with some top-secret components Jaynes wouldn’t let us in on—to produce a CV joint that can operate at angles of up to 80 ...
