I know the 6112s are semi-new to the community. My question is what would be the lowest possible notch I can install these and still have enough clearance to fit 275X 65R 20 KO2s. I’d imagine the notch settings are similar to the 5100s accept there is 1 extra notch I believe. I have been searching online for the past week and cannot find anyone that confirms the lowest possible setting to fit these tires. I know I can install them at the highest setting and fit just fine, But I am trying to keep rake in the rear due to occasional towing and i do not want to add a leveling block to the rears. I was thinking the third notch (1.25” of lift) would work but I’m not sure if It will get rubbing.  Does anyone have any idea on this? I currently have a 2.5 inch leveling spacer but do not want to install it when I switch to the Bilstein 6112s. Thanks!

I installed 5100s 3rd notch from bottom or 2nd notch from top for 1.85” of lift. I still have 1.5” of rake which I like for hooking up trailer, then truck is near level with 500lbs tongue weight. Lowest ring on 5100 was stock height. 

 

Email or call bilstein, they actually respond to inquiries with meaningful answers unlike most companies today.

I agree the third notch is  the perfect height for somewhat of a level but still keep some usable rake. I just want to be sure that my slightly oversized tires 275X65R 20 will fit at the lower level without rubbing. Its Good to hear their customer service is useful. I will shoot them an email also. I was just hoping someone on here had some experience with this set up and tire size 1st. Thank you for the reply.

I currently have a 2 inch RC front spacer as well... 275x55r20 are stock size and will fit with no lift at all. I currently have the 2” RC spacer installed as well and the 275x65 fit great i am trying to figure out how low i can get away with setting the Bilstein 6112 front shocks I am about to install and still have enough clearance for 275x65r20.

I will say this.

If you ever intend to tow at or near the max of what GM spec'd the truck to tow, don't mess with the rake.

 yeah that is the reason I am trying to get the best of both worlds by Finding the lowest possible setting that will still allow me clearance. I am trying to keep as much rake as possible but still have enough room to fit my 275/65/r20s...I also installed sumo springs in the rear so I should not have to worry too much about the rear end sagging.

You won't get any front tire rub with what you're trying to use. Lift it however you want, it's fine.

  I know there will be no tire Rub if I set it to the top notch ... but Are you saying there will be no tire Rub on front tires if I set it to the third notch on the shock (approximately 1.25” of lift)? ...I will be removing the RC 2” spacer when i install the shocks.

Or add airbags...

I am not looking to do airbags at this time...I have sumo springs installed currently and they work great (which is why i want to leave the rear alone i.e. avoid rear spacer blocks) But with the 2 inch RC spacers in the front the front end Becomes just about   level, maybe slightly high in the front, When I have a full load and trailer. I’m looking to be perfectly level or have a slight rake still when fully loaded. Pretty much I do not want my headlights pointing up while driving with a full load and trailer  and I am hoping that the Bilstein 6112 at a lower setting than “maxed out” will achieve this result, The only trick is figuring out which notch is going to be the perfect fit / lowest possible setting for 275/65r20 to fit without rubbing.

You should be fine, I wouldn't imagine there'd be any rub with that.

You'll know when you install the strut assembly.

Your steering wheel will be turned to the opposite side at full lock to allow access.

When you're ready to mount the wheel/tire, turn it back straight and put it on. Go full lock and see if it hits. I'm guessing it won't.

I doubt that lifting it that amount will make it rub. There are 2 K2 1500 Silverados on the lot at my workplace running 275-65-R20 leveled and if there was rub, I'd see it on the tire.

 I understand that when leveled these tires fit perfect because my truck is currently leveled with spacers and they do fit perfect without rub But i will be removing the spacers when i install these new height adjustable shocks. The Bilstein 6112 shocks that I am going to install are adjustable height and have 4 or 5 height settings on them that  range from 0-2.0” or so of lift. My question is do I need to set it to the top setting (2”) in order to fit these tires or can I get away with setting the shocks at 1.25” which would be the third notch/ lift setting on the strut...  in order to adjust these shocks I have to compress the spring and move a metal clip. So installing the shocks and looking for Rub Then making adjustments on the height would be a lot of work due to the fact the shock needs to be removed and the spring needs to be compressed each time an adjustment is made....  If I cannot figure this out Before I install these shocks then unfortunately I will have to do it the hard way and install them look for Rub and adjust as needed. But I am trying to avoid that at all cost LOL.

They should be able to tell you what the lift is for each setting. 

 

If you have someone turn your wheel lock to rock and look at your current tightest clearance with your 2.5” level, you can estimate your minimum lift you need to clear wheel/tire combo.

 

i have 285/70/17 on a stock GMT900 wheel (about 1” narrower wheel tha stock K2xx wheels) tire comes out to 32.8”. They didn’t rub stock but were close to inner wheel well at full lock and reverse. With the 1.85” lift from 5100s, not even close to rubbing now.

      Anybody know the part number for moog lower control arms ball joints on stock arms? Bushings, poly and rubber would be a bonus. Couldn't find the individual parts on their site or here.
       
      I'm replacing the UCA's (3.5" Coilover lift) with aftermarket and they're preinstalled with a 1 ton moog problem solver and moog rubber bushings (may swap with polyurethane when wear out since they have a compatible part number). Would be nice to do the same with the lower control arms or have the option to.

      I recently bought a Sierra 1500 Denali because I love this truck but I am now noticing parts are really hard to find, I want to replace or delete my quad steer but have no idea where to start or look. I haven't been able to find anything in hours. Any help?

      I currently am driving on 265/70R16 on my '04 Silverado reg cab 4x2. I live in WI. What size tires should I look for and can I put 17 in wheels on it? I can't afford new tires and 17 in ones are much easier to find. I have found some tire/rim combos reasonably priced but all are 17's. I am looking to get info on what size tire would be best. If I stay with 16's should I get narrower tires? Driving in snow is a major consideration. Any info would be greatly appreciated! Thank you!

      Recently bought a leather steering wheel from a 2012 2500 sierra. I swapped it into my 2007nnbs silverado ls/base model. I've searched for hours trying to find the correct information on what I need to get the radio controls to work. The harness that came with the wheel had 1 more wire than the ls model did. Original harness had 6 wires. New wheel had 7 wires. Everything I looked up said the swap should be plug and play. But it is not. I need some help to know what I really need? New clockspring? Different harness? Harness behind clockspring? Or is it just not compatible at all? Picture is of new steering and harness that came with it
      Thanks everyone!

      Okay guys I bought this truck from a dealership in September. It was used and I got a 30 Day warranty. After the 30 day period, this is what’s happening. I got in my truck and noticed a rough idle. My truck would shake and out of no where the check engine light starts flashing and my traction control light comes on. I took it to my buddies and we got a P0308 Misfire Detected Cylinder 8. So I did some research.. I also had a code which was P219B. Air/fuel mixture ratio. 
       
      I changed the spark plugs.. didn’t work. I moved coil packs.. the misfire didn’t move. So we watched Live data on the scanner and injector 7 was acting up. So we replaced all the injectors on that side and this truck is still missing.. I’ve ran seafoam through it and cleaned the throttle body and MAS.  My buddy things I have a valve issue or something wrong with the cylinder…
       
      there is no AFM deleted or anything of that sort. The truck has worked flawlessly until now. 135,000 miles on it. The rocker arms all
      looked great.
       
      please someone give me something to try. I just want my truck fixed lol.  
       
      posting a link below of what it’s doing…
