What's causing vibration?

My 2014 f250 crew cab, single wheel was about an inch low in rear so I installed a 5 inch procomp level kit which now gives me a slight rake which I like and which should level out when I hitch a trailer. However, now when I start slowly from a start I get a rumble strip type of vibration at right about 10 mph. Any ideas or suggestions on what may be causing it or how to remedy? Everything is stock other than the rear level kit. Thank you

Make sure u bolts are tight and did you raise the carrier brg. A 5" lift should see 1"-1-1/2 spacers for it to smooth out driveline angle.

Sounds like drive line vibrations like mentioned above. It can be axle wrap as well. The rear spring s twist up on acceleration from a stop causing the rear drive shaft to be out of plane with the pinion. Blocks at times can cause this.

Thanks all. I took it in and they put the smallest shim from the procomp kit and that seemed to solve the problem as it would only happen occassionally. I appreciate the advice.
