Need Suspension Help!

[foreverfalcon40]

I have a 1999 Chevy Tahoe. Its only dropped 3in in the front ( I like the raked look for the winter) I raise it back in the summer for bigger rims. I just spent $500 on tires and want to protect my investment as much as possible. I was going to get an allignment done but for $200 and a promise it won't be perfect, I opted not to do it. He advised that I go online and find a camber, caster kit, ball joint, or control arms to help compensate the difference. He also suggest I raise it a 1in but I like it this low. I've tried searching a little online and ONLY HAVE FOUND kits for the 2WD version.

PLEASE DIRECT ME to a place for 4wd!

Thanks..this is my first post and can't wait for more!
