When you lift your Jeep Wrangler's suspension system to make room for larger, taller wheels and tires, you must make other alterations before it's ready for off-road use. Raising the frame and/or body of an off-road vehicle moves it away from the differentials, which cause the drive shaft angles to become extreme. This can and often does result in binding, premature wear, and vibrations. One inexpensive way to correct the problem without replacing the drive shafts is to install slip yoke eliminator kits on your Wrangler. The sets we sell can lengthen drive shafts by several inches, which should restore the appropriate angle of the driveline.
