Bare with me...I'm new here. I wanted to post a few pics since this forum has helped me figure out what I wanted to go with. Hopefully, this will help someone else out. I was looking to level my front end without giving up any ride quality, as well as get a little bit bigger tire without losing any gas mileage. I wanted to/and will eventually go with a 295/55, but going from about 42 lbs per tire to about 61 lbs per tire seemed like a big jump. I was going to get a programmer, but I read that with these newer trucks, the dealership can tell if you had programmed it, even if you programmed back to stock, and it could void the warranty. So, I decided I'll wait until my warranty is up before I go with a heavier tire and a programmer. I went with the Bilstein 5100 Adjustable Ride Height Shocks at highest setting (about 1.86) and 275/60 Nitto Terra Grappler G2 on stock 20x9 GMC Wheels. The tires are not an LT, but are an XL, which means they are a 4-ply tire with an extra load rating. They ride about the same as the tires that came on the truck and are the same weight. I do a lot of highway driving with very little off road driving or towing, so I was ok with not going to an LT tire. As far as the 5100's go, couldn't be happier. I read that the ride would be stiffer, but better. Didn't understand what that would feel like until I drove it. Much better...no more bounce. Even my wife thinks it rides better. No rub at all.

275/60, is that bigger then what you had? If so, you recalibrate the speedo? Will that affect "actual" mileage if you dont calibrate?

Yes, I had 275/55. Same width, just an inch taller now. I did not re calibrate, but I need to as I think I am off about 2-3 MPG. So if my speedo says 80, I'm really going 82 or 83. I haven't tested it yet, though to know exact. I am going to run by my GMC dealership and see if they can re calibrate the speedo for me, as I have read that they will for a small fee. I would like to go about an inch wider, which would put me into a 295/55, but I'm not ready to go up that much in weight.

I recently joined as well. I have been reading for the past 2 weeks just on this one forum. I have been waiting for someone to post pictures of a Pepperdust Sierra with a level. Yours looks really good. Did you happen to take measurements before and after your install? I have been thinking about a 2" RC with Bilstein 5100's but I am gonna try and fit a larger tire.

Thanks. Yeah there's not too many of this color yet. I search around as well. I didn't get exact measurements but my front wheel well was right at 36" off the ground, and now I'm right at 38". I wish I would've take exact measurements, because everything I've read about the 5100's is that at the highest you'll get 1.86", but it sure seems like I got a full 2". I know there's not a lot of difference, but needless to say I got every bit of 1.86". There are other forums that have a lot of discussion about using a 2" RC with 5100's. I found that the best thing to do was type into Google or Yahoo Images what I wanted to see. Most of the time, the photos are linked to a good forum.

Don't bother with asking the dealer to recalibrate for the taller tires. Been there and was told "no". All the factory tire sizes are close to 31.75" in height, regardless of the rim size. My dealer was straight up about it with me, he said they couldn't do it, and if I used an aftermarket programmer, to even simply adjust for the tire size, GM considers it a "modification" to the factory programming and can/will null your powertrain warranty if you have any issues later. He said it was best to be aware that the speedo was off by a little and just live with it.

Ok, cool. Thanks for the heads up. Guess I'll just live with it, then and won't waste my time.

Looking for my 2016 Sierra. Which Zone 1.5" BL did you buy? The website only lists a 2014-2015 Chevy/GMC 1500 1.5" kit.

I purchased the BL for 2015-2015 models. The instructions actually include steps for 2016 models. I'm not sure why they haven't revised the kit description.

Thanks! I'll call and ask them why it hasn't been updated.

FYI. I just got off the phone with Jeremy at Zone and he told me that they will be coming out with a kit for the 2016 models but it is different from the 2014-2015 C9151 Zone 1.5" BL Kit. He said the bolts should be different and the parking brake bracket will be different and the new kit should be available "soon". That was the best he could offer me.

He told me on the phone that the instructions were updated "prematurely"...

Nice truck! Love those front ends, especially color matched.

    • I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?
    • Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date. 
    • And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access. 
    • Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.
    • Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.
