lowering question
 

does anyone know about the average cost to drop a single cab a couple of inches and level it out? maybe about 2 in the front and 4 in the back?

if you buy pre arranged kits you are looking at 400-600+

if you buy used or individual pieces you might come out cheaper. But you will find out quick that you get what you pay for, If you buy a cheaper kit, it might not ride as nice as a more expensive kit. Also the quality might be lacking in the cheaper kits

i saw a 2/2-4 for about 300 from beltech. does that mean 2 in the front and my choice of 2,3, or 4 in the back?

sounds like it. You sure its one that fits your year truck?
