I need to know what kind of leaf springs and torsion bars to order because mine are sagging badly. Truck is a 2003 1500 laramie with the 5.9 gas engine, I'm the original owner so I have all the documents laying about if it matters.

 

I dont think those 2 items make any difference what package you have.

Off-Road package ($870-$1,405) with unique 17-inch aluminum wheels on LT275/70R17 off-road tires, 3.92 rear axle, limited-slip differential, skid plates for the transfer case and front suspension, special shocks, tow hooks, fog lamps, and a heavy-duty cooling system.

If anything, maybe the torsion bars are torqued a bit more, but I dont think that is the case either.

 

I have everything you
Just listed except the 3.92 diff.....so should I assume I have off road suspention too?
