Exactly what I wish I could have done! Perfect.
I can't remember if I've posted on your thread or not, but I discovered this van when reading and then following bknudtsen's build thread; and have started following this one as well ... this is one of my favorite builds on the site, keep up the great work. Love this van.
Really nice work on the bumper!
How are the SSBC brakes treating you and what size rotors are you running with them?
Thanks!
Sadly, I'm not yet. SSBC's customer service is by far the worst in the industry. I've been waiting 4mos for the front 8piston calipers. Was told 2wks, then 3wks more...now another month later and come to find out that they're changing their cast 8pot calipers to forged. Why, I have no idea...not that it's a bad thing. However, I did just have a LF factory caliper hang up on me last weekend(1 of the 2 pistons froze). It manifested itself by the van pulling hard to the right under braking(RF was slowing the truck down more than the LF since the LF didn't have full braking force due to 1 of 2 caliper pistons being stuck). Thankfully I was on the way to MG's for the bumper install vs eastern OR BFE, so it was remedied at MG's(Napa has nicely rebuilt loaded calipers and hardware, comes with a roadside assistance program--ok worth $60 reimbursement, but still, better than nothing).
Will be running the 13D"x1.5T" factory size. Doesn't seem to be a way to easily increase to the later 14" or 14.5" size.
F550 brakes will require a 20" wheel, as the F450 and F550 trucks only came with 19.5" wheels from Ford. There are no 16-17" wheel available due simply to weight ratings of axles and load carrying capacity. Obviously this is not an issue in a van, but now you have inhereted their design and must use a 19.5 wheel (tires can't be aired down much due to bead and sidewall construction) or a 20" wheel, which gives you a wider range of tires from which to choose.
Check out Stop-Tech and BAER, I know they have kits for 3/4 ton and 1 ton trucks, but no personal experience with either one.
pulled from a Ford truck forum:
No the 550 uses 15 inch rotors that is the reason for the upgrade. You'll need to find a set of steering knuckles off a 550. Check the junkyards cause ford wants 250 a peice for the knuckles. I'm fixing to do it to my truck. You'll also have to go to a minimum of 19.5 inch wheels to clear the calipers and rotors.

There is also a suggestion that a 19" or even some 18" wheels may work with the correct offset. Usually you want to add at least 3" to the rotor diameter to ensure adequate caliper to wheel clearance.
