Can you elaborate on the "performance balance?" I have the same tires (XL rated). Could only get the road force balance down to 16 & 19 lbs. on two of the tires and it is evident at highway speeds.
I thought the same thing... then I realized that the reason the full part number wan't listed was because they are only taking preorders now. They mentioned in their blog on January 3 that since Bilstein released the Tahoe/Yukon versions that they expect the pickup 6112's to be available soon. Still waiting.
One time while I was jump starting a tractor from my truck my radio shot to full volume and kept returning to full volume immediately after I turned it down. Restarting the truck didn't help. Disconnecting the battery fixed it. I attributed it to the voltage being thrown off when I was connecting or disconnecting the jumper cables.
