I really need to lower the bed height of my '15 F350. With my new fiver I am sitting at 13'5" give or take a half inch. This is way to close to the 13'6" of some overpasses. I have raised the pin box as far as possible and the Pullrite slider isn't adjustable. I have read in the past of others taking out the F350 blocks and installing F250 blocks. If I do this, what issues will I have? I have read of driveline issues?
What parts do I need besides the new blocks, and new axle u bolts? Oh and I guess shorter shocks for a F250.

 

This might be a question for the Super Duty section found here Super Duty & Heavy Duty - Ford Truck Enthusiasts Forums

Although, from what I have read the F-350/250 are 99% the same truck when talking about SRW. I don't think you would have any adverse mechanical problems if you swapped for the lower blocks.

 

I would not worry in the least about your height. 13' 6" is the max height a vehicle can be to safely pass under a bridge. The bridge is NOT 13' 6" and it doesn't mean at 13' 7" you would hit. Remember, missing by an inch is missing by a mile. Same thing...

 

Mine comes in at 13'6". I have no problems. If an 18 wheeler goes under then I do too.


I have a rand McNally RV GPS that will take my height into account.

 

If you are on a federal highway. The minimum height is 14 ft per interstate highway standards.

 

Good point Scott. I also have a GPS that you enter your height, width, and weight. Might be a better investment than lowering the truck.

 

First, I would crawl under your truck and make sure you actually have the 4" rear axle blocks as somewhere here someone noted that their F350 had only 2 inch. Then that change out - I would do that only if the 5er is riding nose high. Our current 5er is riding pretty level with the current truck but the last truck-trailer combo rode a bit nose high and was at 13'6" plus over the vent covers. We never had a highway problem though did pull one of the vent covers off in our neighborhood 2X - both times with power lines that had sagged way low. The power company have now fixed the lines after a moving company 'wiped' them out and I fixed the cover.

 

I think you have that backwards Dave. All the 350's come with 4" blocks. Some of the 250's come with 4" blocks but most have 2". The only way a 350 would have 2" would be if someone swapped them before you owned the truck but the OP bought new so....

 

2WD F350s of the pre-2011 era had 2" rear suspension spacers, 2wd F250s had no spacer.

 

My 05 F-250 2wd had 2" blocks.
