I made an account just to thank you for posting this. I recently purchased a 12' Silverado CC LT Z71 and I want to go up a little bit without breaking the bank. I found the 2.5" RC kit, noticed the video said I could go up to 285/70 tires, and was like "Hmmm....prove it." I did some googling and found your post! Thanks again for posting this. I'll be whipping out my card to order the kit soon.
