Spring load handlers ?

I just bought a 2012 2500 HD and it has some springs attached to the rear leaf springs. I put 1400 lbs in the bed and it only went down a few inches if that. I think these springs or hurting the unloaded ride by applying pressure to the leaf springs. Also rear of the truck sit up much higher than the front. Does anyone know what these springs are and how to get them off. I took pictures but I'm a dummy and don't know how to post them are maybe you can't do that here. They seam to hook on the back without bolts but are bolted in the front from under and over the leaf spring with a bracket. They have adjustable nuts on them but when loos they still seam to be held in place by torque from the leaf springs? Anyway the highway dividers in Louisiana are bad and I don't need any extra payload than this truck already has. Just trying to smooth out the ride a bit, I know it's a Truck and I bought a truck but I really think this is taking away from the ride.
Any help would be greatly appreciated.
Thanks Techeman

    Road Master pulls against M/L not allowing spring to deflect properly should never clamp anything to your m/l yes it might hold truck up so
    would a 4" x 4".

    Not sure, that could of been done also. Do you know how to tell if he added a spring?

    They were pretty easy to put on. Should be easy to get off.

    IIRC I had to lift the truck and let the rear axle hang loose. Take off the wheels, then bolt on the brackets around the spring pack, lay the coil on top with the "Hook" placed over the end of the spring pack. Then tightened the coils so the "hook" held it all in place. So just try reversing that procedure.

    As you could see there was plenty of room for me to get my I-pad in there and take pictures.
    The front measures 8" from the top of the tire to the fender edge.
    The rear measures 12.5" from the top of the tire to the fender edge.

    Does anyone know if this is normal for a 2012 2500HD?

    Thanks TecheMan

    I can't imagine it being a worse ride on bad freeway dividers. The rear has no give what so ever on quick drops like that. It feels like a F550 suspension would feel unloaded. I can't help but feel these are hurt the unloaded ride of this truck. I'm not a mechanic but I want to take the off is it a difficult job.
    Also I measured the fender walls from the tires and the back is 4.5" higher than the front is this normal. I think it's putting pressure on the front suspension and hurting the ride up front also. The guy who had the truck before me had a large fith wheel and all I have is a pop up and 20ft bass boat. Now down the road I will get a TT but nothing very large though.
    Thanks Techeman
    I really appreciate all the help from you guy.
    And a special thanks to you Jim for helping me post the pictures.

    Yes, those are Roadmaster Active Suspension.

    They do lift the rear up to an inch. But you can reduce the spacing between the coils and reduce lift to 1/2" or less if you want.
    They really help with bounce and jitter on rough roads, and axle wrap. Make the unloaded ride a tiny bit stiffer but not bad IMHO.

    Help a bit when you're loaded up as well, especially with my F150, but I wouldn't think you would need them when loaded in a 3/4 ton. Your overload springs would do the lifting then.

    Surprised to see them on a 2500HD.

    That is a "Roadmaster Active Suspension". Google it. The system has a pretty good reputation.

    Here are his pics folks. Any idea what he should do? I've not seen these before, so I'm stumped.

    Thanks Jim I sent them to you. I feel these things are lifting the rear of the truck and adding strength to the payload while hurting the ride and lowering the front. I sent them right from my I-pad using my work e-mail.
    Thanks Techeman
