NORCAL SS CUSTOM rear TBSS kit tested and now on my webpage. These shocks are the hd version which belltech makes exclusively for me. i tested them for a few weeks on customers trucks and all agree much better then regular version that comes standard which everyone else sells. I offer this in a 2 and 3 inch drop version for the Trailblazers. Below link is for 3 inch. Any questions just ask.
