2011 Ram 2500 suspension question

Picked up my new fifth wheel yesterday and service guys couldn’t get it level. There are 3 plates under the leaf springs on the truck’s rear suspension they said they’d never seen before and are preventing the suspension from squatting at all. 2011 Ram 2500 Cummins. I’ll try to post pics later from PC instead of phone. Any ideas? They speculated it was some sort of overload since this used to be a ranch truck. Or maybe a lift kit even though it’s not a single block.

    ^^^This. That have nothing to do with “squat”.
  • If they’re just spacers on top of the axle they aren’t adding spring rate. Yes the truck may be too high for your purposes with them but they’re not preventing it from squatting.
  • I removed them on my 2017 and it dropped it down enough to allow me to level my trailer. I have a Reese Elite Airbourne Sidewinder that have an air bag in the pin box. This causes the pin box to mounted lower than what it normally would be. I have my hitch in the lowest position and I still have 9" of clearance now.

    When we did it we just placed the 3 blocks on top of the existing spring pack that allowed me to reuse the stock U bolts. It lowered the rear of the truck by about 2".

    It does appear that the upper bolt on the caliper is going to be hard to get out. It might need to have U bolts loosened and then raise the rear of the truck.

    I'm not going to worry about that right now as my truck only has 1400 miles on it so they should last for years before I need to change them. I'm retired so I have to make a point of driving the truck once in awhile to exercise it some. We normally drive one of our other cars. The trucks main use is for pulling the 5er. So maybe check your rear pads and if close to needing changed then do it now before moving blocks.

    I use my exhaust brake all the time also even when empty and using the down shift button on the gear selector I manually downshift myself to avoid using the brakes. It becomes a game for me to see if I can slow down enough with just a tap on the brakes for a final stop.

    This is what worked for me and might not work for others.
  • If you take any of them out, watch the brake caliper mounting bolts closely. On some trucks, taking out the spacers will make it impossible to get those bolts out without a lot of work.
  • I had on 01 2500 ram it had a rather tall block under the rear springs came stock like that. On my 17 3500 it has 3 or perhaps 4 of those plates. Those plates are in place of the old block. They are short enough at least on mine and are no longer than the blocks that was under my 01 they should not be keeping the springs from flexing. I doubt someone changed out the block for the plates. I know my 17 3500 does not squat near as much as my 01 2500 and actually had to raise my trailer a couple inches just to get the bed rail clearance required. On my 17 those plates are about 1/2 to 3/4 inch thick iirc and you may be able to take some out but I would not take them all out as they support the spring pack on the top of the axle. I know my 17 is not an 11 so it may be different.
  • I suggest you post your question over on the Turbo Diesel Registry link.
    I'm sure someone there is familiar with your configuration.
