Chevy & GMC Vans

So I have always thought the van was a little low in the front, took measurements and sure enough it was. So I threw it up on the alightment rack tonight and set everything up. Everything was in spec. but more to one side of the spec. Went under the van cranked up the bolts on the bars 6 turns and the front end came up 1.25" Toe, Caster and Camber all stayed, jounced the van 3 times, height increase stayed and all three stayed in spec. Al is good, however now the front is only .25" lower then the rear, I like the back being up a little bit to take a load/ trailer if needed. So how do I get an inch more in the back, is a 1" block a good idea? 2003 AWD with Majestic Conversion. Thanks

I used Monroe air shocks to raise the rear of the "Smilievan". It's easier than using a block and you can control ride height according to load.

Thought about the airshocks, I have them on my cherokee. But I went with 4 Sensatracs instead, that was 3 weeks ago. And to night I turned up the front go figure, now I want a little more in the back.

a set of overlandvans shackles, on its lowest setting gives about 1 inch.
