Does any one know what it entails? So far I think I comes with the 36mm front stabilizer bar and different shocks up front. I think the front springs and rear springs/shocks are unchanged. I wanted to verify this though.

 

The rear springs are different there is a lot of variation in springs and shocks on the NNBS.

 

ride height is probably a bit lower, you can't get the vmax tow package with the z60,
if i remember correctly.
my 2wd with tow package sat as high as a 4wd z71 stock
