Zero Rates ??\'s Im sure this has been covered, and i have searched, but found nothing to fit "my" application. I have a 4" rough country lift (all spring), my t-case has not been moved/lowered. The driveshafts have not been altered either, I have about 1 inch of spline showing on the front and the back shafts. I want to add zero rates to the front to allow a little more clearance, and some in the back to keep the truck level. Am I going to run into trouble with drive shaft length? Pinion angle? vibration? thanks for any input.
