Body lift kits?

I have a 1999 Chevy Z71 (new body) and ive been looking into getting a 3" body lift on it with 33's. Ive heard that you can find a body lift kit for as cheap as 100 bucks. Does anyone know where this might be or know of any other place that has body lift kits this cheap? Ive only been able to find them for upwards of $275. Thanks for any help

you are in the C/K gallery , they are only that cheap for the 98 and below C/K trucks. you need to be in the silverado gallery.
