I'm not the one with the Sprockets but I'm running 33x12.5x20.

Sprockets are ?

Thanks bud! I lost about 2 miles per gallon. I'm averaging about 16-17 now but on highway I get up to 21mpg. Very happy! Only rubbing fender liners on full lock and a little more in reverse. No big deal though, either go to trim or pin back.

You should rub liners but should also clear the upper control arms fine. Liners are easy, either trim them or pin them back. Good luck!

What year truck do you have? I have a 17 All Terrain with the same set up but with et37 and 1.25" spacers and still rub at full lock on liners. My offset is about +5 with spacers. You'll rub slightly more than me if you have a 16, 17, or 18.

Would highly recommend it. Great customer service. Fast shipping (ordered on a Wednesday night and had it Friday). High quality and at $75 you can't go wrong. ??

Thanks brother! Motofab 2.5" level, rear is stock. BORA 1.25" wheel spacers. Toyo R/Ts 33x12.5.

Quick detail after picking up from GMC body shop. Roof damaged from transportation was fixed and covered under GMC.

Detailed it after getting it back from the body shop! Had transportation damage on the roof upon arrival from purchase date. All covered under GMC.

Thanks brother! Yes, the stock 20" All Terrain wheels. I would definitely trim the studs some on a 1" spacer. I did not trim any on mine as I do have the "pockets" in the back of the wheels which I did not know about until I unpacked my cut off wheel. Surprise to me! I did a quick measurement with my pinky finger and had a little left inside the pocket. Very pleased with the poke and stance of the truck after the BORA spacer. HIGHLY recommend these to anybody in the market. I'll get a picture of the poke when it's not snowing here... Thursday is suppose to be 75° here in wonderful Chicagoland.

Finally received my BORA 1.25" spacers. Glad to report no more rub while on a 2.5" motofab level with 33x12.50's on stock AT wheels!

Bought my 2017 Sierra SLT All Terrain in January. Installed a 2.5" motofab level and 33x12.5 Open Country RTs on the stock 20s. Rubbing upper control arms at about 25 degree wheel turn. Ordered BORA 1.25" wheel spacers. Hoping this will correct my rub!
