What does a level do ? Raise the rear ?

Opposite, it raises the front and gets rid of the rake. If you wanna keep the rake, you can add to the rear like what others have mentioned with either an add a leaf or a block.

My ‘18 with Halo Lift Boss coilovers up front - 2-5/8” thread below the adjustment ring. 2” block in the rear. And BFG 285/65’s on sock 20’s. Purposely kept a little forward rake, and added Timbrens, because I tow boat, tractor, sports cars, etc. Very happy with how it came out. I haven’t done any towing yet, bit with the power this thing has and the 10 spd, I don’t think I’ll be disappointed.

Best,
