Current clearance height according to the labels on the dash is 9' 7". And if I put a RTT on it will be over the cab not the box roof. With the lift and wheels I figure on being at the 10' 4" - 10' 6" clearance (Awning and solar). I will carry a long reach chain saw just in case .Um, not to burst your bubble, but have you taken measurements of overall height? Typically an ambulance like that will be around 12' tall with stock tires, the maximum legal height is 13'6" (and that's stretching it sometimes) for a vehicle. Throw on those 43" tires and a RTT, you could very quickly be exceeding the 13' mark.
This model Freighliner actually has the lift blocks as an optional part (front and rear). They put the little ones on for the little wheels (19.5") and when they went with the 22.5" you got the bigger blocks. There is 4" difference in the U bolts between mine and the biggest ones they offer. But I will be talking to the guys at the spring works to see if it is possible to get arched instead of flat leaf spring and not have blocks. One less thing to go wrong. The rears will definitely be blocks as changing the arm that the airbag setup swings off would be a major undertaking.You don't plan on using 3" blocks to lift the front do you? Lift blocks and front leaf springs don't go so well together.
I was going to use Freightliner parts but $87 per block and $54 per U Bolt with a 1-2 week delivery was a bit too much to put up with. So off to the metal shop I went. T6061 aluminum bar which I will get machined to size. U Bolts will be custom made by the local spring works (3/4 grade 8 on the rear and 5/8 grade 8 on the fronts). Front will be blocked lifted temporarily and new springs and air bags when I am able to get someone to do them for me. Probably not by expo though.If Freightliner offered blocks in the front and you use Freightliner parts to do the lift then you have nothing to worry about.
OK it ended up at 10' exactly to the roof. So 10' 6" clearance (incompetent DOT surveyor fudge factor). Still well under a normal box truck.Um, not to burst your bubble, but have you taken measurements of overall height?

No locker or limited slip yet. When I work out what final gearing I need I will chase down a full locker for it. I am also considering fitting On Spot chains if I can source a set at the right price.Wow, that went from dorky to bad-*** in a hurry! Can't wait to see it with the final stance. I might have missed it, but is the rear a locker or limited slip? How traction limited is such a beast with 4x2 only?
