Rear lift block ?

[cm351f]

I put a 2in leveling kit on my 250 and now i'd like to put a 1in - 1.5in block under the rear to level back out. I'd like to reuse the factory u bolts but don't think i can. i measured 1in from the top the nuts to the end of the bolts, but only 7/8in of threads left... prolly need longer u bolts don't i? i pull/haul some pretty heavy loads so i'd rather not loose my axel lol.

John at Cobbs Diesel performance is working with Top Gun Customz on a block that is what you are looking for It even has an off set pin that will recenter the axle. Give John a call

Just get a f350 block. I believe it is 4 inches.

I am in the same boat...Looks like the stock block is 2". Ready lift sells a 4" kit with bolts for like $140. The block is cast, just like the stock one.

typically the factory rear blocks are 2" and is not recommended to reuse U-bolts when altering. You can usually find local trucking companies that do their own repairs to make a set of U-bolts for you relatively cheap. I also recommend deleting the 2" stock blocks altogether, and just buying a 3" or 4" block. Be weary of your driveshaft angle though because this can cause excess wear on U-Joints at the rear diff. Just my recommendations since you said you do haul with it, if it were my truck, I wouldn't want any of my blocks to shift.

Considering the 350 uses a 4" block, I'm pretty sure its a non-issue

still dependant on whether the block is a tapered center pin or a non-tapered centerpin. I'm not familar with the 350 set up, but if its anything like my 250, I blew out my rear U-Joint when I was using a non-tapered block in the rear. Bought a new U-Joint and tapered 4" blocks. Now I have no problems.

I just recommend checking it out first.
