I just installed all 4 taillight bulbs with new 3047 LED bulbs. Now the left lower bulb doesn't work besides when blinking (using the key fob, or turn signal). Also, regardless of having my left turn signal on or my right, it will start blinking fast for both. Any idea how to fix this issue? Thanks! Jared

Anyone know if these rims and tires have been put on the 2007.5+ trucks? I would love to put these on my truck but not sure how they would fit?

I plan on putting a leveling kit on it and some chrome 20s off of the LTZs from the 2014 and up trucks with 33's Here are a couple pictures of my baby:

Hello everyone! I have browsed these forums for probably 10+ years but never really posted until now! I used to own a 2007.5 GMT900 Silverado LTZ ext. cab w/ a 6 inch lift and 35s but sold it years ago. Can't remember if I posted pics of it on here before or not. Anyways, I now own a red 2011 Z71 LT crew cab. Pretty much stock for now but have hopes to modify it in the near future! Excited to jump back into enjoying trucks again, now that I'm a responsible adult (33) lol
