A fairly popular upgrade to the 14 Bolt 6 lug SF rear ends is to swap to NBS brakes. So like taking the setup from a 2003 Tahoe or similar with factory rear brakes. These spacers make up the difference in the space needed to bolt them on and get everything to line up.
One thing to note with this setup is you need 16" Wheels or larger.
