1. We recently visited NorCal Truck in Livermore, California, to document the installation of the Pure Performance solid-axle swap kit on an '08 GMC 2500HD. The first step is to get the truck up on a lift and remove all the IFS parts. Starting with a new truck like we did is a pleasure because everything is dirt- and rust-free. If you're considering adding this kit to your used truck, we suggest having the chassis steamcleaned. It often costs around $100 or so for a professional hot steamclean, but it's worth the money.
