Thanks fellas, the rotors them self idk what brand i paid 400 for all four in a shop by my house. and as far as stopping they made a big difference i like how you here a ''woushhh'' sound when coming to a stop.
The kit i bought came with 3'' keys up front and 5'' springs out rear, shock extender, shorter bump stops, and all four nitro drop shock 2 for all 4 corner's.
i love how it rides like stock just a bit firmer. I do bottom out in the rear but only on big bumps next will be the free travel mod.
and everything on the kit is belltech, i love it compared to my old tahoe that was lowered using McGaughy's and it bounced all over.
