Wow this quite the complete build thread. I am not a huge fan of some of the appearance mods, but dang you seem to know what your doing on a lot of this stuff. The interior led work is pretty legit. A few things I would love to see a complete slip from the track if possible. Those 4.10s should help a ton and honestly you should lose the shorty headers/flowmaster. That cam will absolutely love some longtubes and a straight thru flow muffler. We are talking 30+rwhp gain by uncorking that exhaust. Not too many modded suburbans out there. Nice work over all.
