Will a rough County 2.5 leveling kit allow for a 275 70 18 tire without rubbing?

Yes, that's a 33" tire. Should fit without an issue. However, it will throw off your speedometer by about 2mph.

Looks nice Matt. Are your Bridgestones the OEM tires (275/55/20?).

So suspension had settled in after 1.5" rear blocks and i was still not content at only 1/2" rake. I upgraded this morning to the 2" rear blocks posted above and now have a 1" rake plus these are steel and the tampered style thats slightly shorter on the front. I am really happy with the results as I should no longer notice a squatting appearance when fuel tank is full. Also while removing the tire i broke the lug nut lock on one of the wheels as i had tighten it too much previously. Lesson learned. Jb weld did the trick to remove it and now need to order a new lug nut key.

Did you have to remove he wheels to put the blocks in? My blocks should be here Friday, so there going in next weekend ( single digit temps in Michigan ) . Truck looks great, I'm really considering removing the side steps, looks a lot cleaner with out them, Are they a pain to remove???

Yes i worked on one side at a time. Jacked up from side and placed on jack stand. Then moved my jack to the center of differential and jack up diff to remove wheel. Unbolted strut from bottom, then u bolts and lower jack slowly. Swapped in the new block and jack back up. Push the differential to align holes while lift jack and bamm all set. Oh and my truck already came without side steps but i do want to install some nfabs because Iam afraid the leather will start to tear and wife and I are planning on another addition to the family so they will be needed.

Here's a before and after of a 2.5" RC front & 2" rear block on my '16 Sierra with factory 20's.

Below is a pic of my suspension and the angle of my front drive shaft at the wheel. Love the look of the raised truck, but the ride, its another question. I read back thru the last 20 pages of this specific forum, and only found one comment about the ride. Mine feels as if there is rolling resistance, as if something is holding it back. Yes, in neutral it rolls as it should but even then or under power, still feels like resistance. It's only been 2 weeks since I completed the DIY project. Any thoughts anyone? Just searching the web, a ricer forum thought someones E-brake cable might be pulling taught. Any help?

You don't have to take off the wheels. Here's a post I made about replacing the blocks a while ago...

You can just jack up rear leaf spring. I installed my rear blocks a couple of weeks ago and it about 20 mins. ON A LEVEL SURFACE. Place a 4x4 block on your jack so you have plenty of lift. Position the block/jack on the front side of the leaf spring directly in front of the factory rear blocks. Don't put pressure on the jack yet. Take off the u bolts. Now jack up the spring enough to remove the factory block and install the new one. Slowly lower the jack. You should notice the rear slightly roll into place. This is why you need a level surface. It helps to have someone else there to watch and make sure everything lines up while you lower the jack. Once it's lowered all the way reinstall the u bolts. Do one side at a time. It's very easy.

Thanks, I was planning on jacking up the truck from the rear diff, and placing the frame on jack stands, then removing lower shock bolt, and four nuts that hold each U bolt ( each side ) then lower the rear diff to remove and reinstall new block, and U bolts.. But I will give your idea a try, just have to picture what your saying in my head..LOL

BTW, congrats on the new baby

My neighbor said he just finished his blocks.. put jacks under frame. Loosened the bolts but left them with a few threads.... deflated his tires until there was enough room to work with. Removed the one side and exchanged the bolts and block... then did the other side. Reinflated enough to get it all back in place. Tightened--->full inflated---> retorqued. He says he was done in 40 minutes with air tools. I'm pretty sure tool was right. But I'm doing mine the first day it's above 60*.

Thanks Rolling Thunder... I get a lot of compliments on the truck. Very happy overall. I came from a BMW X5, and this actually drives and rides better (for me). I don't think I will ever go back to a car/SUV.

Anyway, to answer your question, these are the stock AT tires on the 22-inch wheels. I believe they are 285/45/R22. They ride very nice, look aggressive and are relatively quiet.
