raising kit for f350 2005 ,6.0 doesel

[Philip05]

I bought my f350 ,2005 ,6.0 diesel crew cab with 74K on the miles, I pull my 5th wheel travel trailer and noticed I keep blowing rear tires out on the trailer rear axle . Problem ,There is what I think been installed on the truck before I got it. either a 4 or 6 inch raiser kit put on it, I have my 5th wheel neck down to the lowest and if I take the 5th wheel hitch down any more I will the bed with the trailer , I am going to try and upload pics to show what i'm talking about . bottom line I want to know if I can remove the raise kit and still use the the same U bolts and shocks. I'm goin to try and ubload pics

If you have the means to cut the length down as well as cut new threads into the u-bolts, re-use them. When I took the blocks out of my rear suspension, that is how I reused the u-bolts.

I really doubt that the shocks being a little long will matter.

Are you sure that it is the height of the truck that is blowing tires on the trailer and not a misaligned axle? If the axle is c@cked off center, then you are literally dragging the tires sideways down the road.

[Philip05]

Not for sure that is problem, but like I said when I have everything hooked up the front of the trailer is at least 4 to 5 inches high out of level. So just figured that may be causing undue pressure on rear tires,?

[Philip05]

There are 2 raising blocks installed (or looks to be) one about 4 inches and the other looks about 2 1/2 inches .If I remove just the larger one, I will have enough threads on the the U bolts ,any more than that I will have to thread the u-bolts more. I'm pretty sure that will lower me enough, What about the front , in the picture there looks to be some type of raiser in there ,does that need to come out also?

[Karls03]

I"d take out the lower block, it's probably the same height as the front spacer. Also, the top block is the factory block, that is a bump stop sticking out of them.

[Philip05]

So the large spacer on top is factory? correct ,and the smaller lower one is the one I can remove? Also the one installed in the front ,can I just leave it there

if you remove the rear, remove the one up frony otherwise the nose of the truck will sit high.
