lowering the rear about 2"
#3
I was wondering kinda the same thing...
I also want to add to the question...
From my observations... alot of the vibration problems come from people with SuperCabs reguarding the 2" drop and driveline vibe....not regular or SuperCrew....
Are there any people with a Regular Cab that dropped the read 2" and ACTUALLY had to use shims? Any vives from 2" drop on a regular cab?

I don't think it's not understanding so much as it is wondering if they're gonna need the shims. I went through the same stage when I decided to buy mine.
I had a 50/50 chance of buying the less expensive ones and not having the vib. I finally decided I didn't trust my luck and went with the Groundforce. Glad I did........

As this illustration shows, 9° on both sides would be ideal, but 10° & 8° will still work. Therefore, it boils down to where you start out from the factory. A 2” drop could eliminate a vibe in some cases.

I can see the thinking in putting in the shims while you're already under the truck...
My thinking is... I dont have any vibe now... will dropping the rear give me some vibes?
Thats why I asked is any other regular cab owners got a vibe from dropping the rear...
If someone said they had... I would most certainly shim it up while I was under the truck.

Some trucks are more picky than others. The '04+ F150 isn't very tolerant of pinion angle changes to begin with, you really won't know whether you'll get a vibration until you try it. Mine had a low speed driveline vibration from 20-30 mph, felt like driving over rumble strips. I've since raised my DJM shackles up to the 1.5" hole, no more vibes, although I will shim it someday just because the truck looks that much better at 2".
