    lower the torsion bars up front, or lift the back higher.

    That truck has 2" blocks factory, did they swap to a bigger block? Do something with the shackles in the rear.

    When stock most trucks sit higher in the back, so when you put a load in them they level out. Most IFS lifts I have seen on the market lift the front higher than the back to level the stance when empty........what happens is that then when you put a load in it the back looks lower, even though the springs have deflected the same amount as they always have.

    Considering you still have the same rear springs PLUS an add-a-leaf there is absolutely no reason the rear should sag any more than it did before....actually it should sag less. It's most likely just the perspective view of the truck with the lift installed.

    i thought i was seeing things at first but the rear bump stops are almost hitting the rear end with a load. what should i do? buy new rear springs,blocks ,etc. if so which ones ? also when i just looked at my truck these idiots at 4wheel parts in san leandro did not check to see if the rear centering pin on rear blocks was too long . so the rear end pivots/rocks front to back. i know i need to cut the pin a little. but why should i have to do it ? i will NEVER let those IDIOTS work on anything of mine again . they said they test drove it 10 miles , but the speedo don't lie. 1 tenth of a mile. :crazy:they are now on the don't do buisness with list, cause they will either F your truck up , not install parts correctly,over charge you,not return all of your old parts and not give you their advertised discount. THEY SUCK!!!!!!! :mad:
