No, mine are 2.5" Raptor blocks and OEM U-Bolts. The shims aren't thick at all, so if you have any thread remaining with the U-Bolts you're running now you shouldn't have a problem.

I thought the raptor blocks already were tapered..... interesting. Strange they wouldnt vibrate on a raptor but do on our trucks.

Nope, Raptor blocks are completely rectangular in shape. The pads on the axle may be welded differently though since they use a different axle than regular F-150's. Not saying that's what it is, but would make sense that the correction is done on the spring perch versus using an angle block.

Sorry to sound dumb but how is the shim oriented? I might have some time to put them on but don't want to make the problem worse.

Thick part of the shim goes toward the rear of the truck.

I installed the pro comp 3 inch blocks and ended up with the driveline shutter/vibration between 20 to 40 km/hr (12-24 mph). The instructions were not very clear as I could not locate the arrows that were referenced and I ended up putting them in the wrong way. I didn't notice the first time that the blocks are tapered. Changed them around and vibration is gone. Im pretty stoked I don't have to take it in to suspension shop.
