Have an 18 F350 DRW that I would like to lower the back end on a couple of inches (or whatever amount the new blocks give). I read through the thread and it appears as though the DRW trucks need a different block than SRW? What Ford part number should I look for to accomplish this? Can I lower it a couple inches then still use ride rite or firestone airbags for towing or gooseneck?

Is there another way
Been following this thread from the beginning, and as someone who lowered an F350 (2016 CCLB Platinum) and then put it back stock because of the driveline vibration that it caused, I have a question. Has anyone tried lowering the rear of one of these trucks by lowering the spring rate (removing leaves or softer springs) then installing air bags to get the load carrying capacity back (better ride)? BTW - I sold my 16 and am back in my trusty 7.3 for a couple more years. My rear springs in my 7.3 are still stock and no doubt sagged out (which I believe is why it rides so much better than the 16 did), but the airbags bring it right back to where I need it to be towing my 5er.
In case you are wandering why I got rid of the 16: Ford could not fix the bounce in the rear end of this truck (it was a long bed). They did try by installing a damper on the hitch, but it didn't help.

Lowering the rear (AKA: reverse level) doesn't reduce ground clearance, nor does it reduce suspension travel. The only thing it does affect is exit angle (my bumper is about 1-1/2" lower than stock), and airbags can offset that if needed. Other than getting off pavement onto grassy areas and/or dirt/gravel roads, I would dare say that the vast majority of these trucks are never taken off road. So what's your point?

yes it reduces the departure angle, quit a bit actually, depending how much the rear is lowered. the break over angle is reduced as well. i guess its all of little importance if folks never go off road. to each their own

I lowered my CCLB with the PMF blocks, new bolts and nuts.
I can now see into the bed... Lol- I'm vertically challenged...
I parked next to another CCLB and the difference is definitely noticeable Walking by and at the tow ball. (dropped 2")
we'll see how it rides at 80mph in the morning...

Does your truck have two driveshafts? I too used the '16 blocks with no taper but I have a bit of vibration from 45-65mph. I have one shaft on my 18 ccsb 4x4 f250 6.7. I've ordered a 1.5" with 2.5 degree taper .......hopefully that'll fix it.

It's a one piece drive shaft. Since these vibration posts started showing up I have paid close attention and cannot detect any vibration, even pulling my RV.

My 60 mile round trip at 80mph was nice and smooth.
Can't wait to hitch up the boat and see if I have a vibration....
