Reason I ask is cause I had welded up everything for the rear in front of the diff and bought 12in 140lb springs for the rear and u can see in the pik that as soon as I set down the truck down is put the springs in a bind and pretty much went all the way down that the reason I ordered the qa1 kit for the rear with 200lbs springs it's still missing the batteries in the rear anti roll bar and fuel cell so they're was no point in keeping my setup plus the qa1 kit puts it on the outside of the frame so I can adjust them easier
This is wat I looked like when I set the weight on it
In this pik I put a 4x4 piece of wood to move it and so u can see the rear setup I had moreless
