'04 Silverado RC level kit.

[cghbuilder86]

I am thinking about installing a rough country level kit on my "04 silverado. Just the keys to re-index the t-bars. The difference in my application and most folks is that I don't want it as high as I can get it to accomodate bigger tires. I'm probably just going to keep my stock size wheel and tire so my speedo, performance, and best mpg will all stay the same. I'm just tired of the front drop look. I'm measuring 35 1/2" front fender to ground and 38 1/2 rear fender to ground. would like to see it level but no rear drop. My question is, if I install the new keys with the adjusting screw at the exact same position they are in now and the front is a bit too high how would I lower it? Just back them out an equal amount on each side? Another reason I am asking is because I figure if I raise it 1" or 1.5" I'll have a smoother ride and stand less chance of excess wear on front end parts than if it is raised 2"or 2.5". I know it will need an alignment afterwards. Just seems like it standing level would be a nice change.
