I have a 2004 2500 quad cab long bed diesel 4x4, I am pulling a big country 5th wheel. The rear of my truck sits a little high, thus I have to have 5th wheel a little nose high to clear bed rails. Any way to lower the rear of truck some to get it to sit level?

 

Might be more practical to flip the axles on the 5er if it hasn't been done already.

 

You can remove the spacer blocks from over the axle to lower it some but I understand that the spring will be in the way of removing two of the bolts in the brake housing. I therefore did as was suggested above and had the 5er axles flipped.
