Good evening. I wanted to check in and see if you were able to get our truck aligned. I am running into the same problem. I have a 2021 GMC Sierra SLT 1500. Just added a BDS 4 inch Suspension lift and the install shop, recommended by BDS, could ot get the truck in alignment. I do not have a print out or remember what the descrepancies were, but from what I say, looked alot like yours. So just checking with you. My truck is still at the shop. Thanks.

It is at a shop that does big trucks - they hav some that have 12 inch lifts etc. They do have a big rack. I installed on my truck the 4 inch lift and I am running 20 x 10 with a 0 offset. 33 x 12.50 tires. I have read, on a Toyota site that the Bilstein ride height adjustables could be the issue, but they are set at stock... so who knows. I am calling BDS tomorrow to ask their advise on it. After that, I am not sure what the issue is or how to get it fixed. I am thinking about having them pull the struts and put the Rancho's back on to see if it makes a difference. I am running that new 3.0 ecodiesel.

Did it have any issues with alognment. I have a 2021 GMC Sierra 1500 SLT and just added the 4 inch BDS kit. I also added 33x12.50 20 General Grabbers. Issue is that the shop who was recommned by BDS in my area cannot get the truck back in GMC specs with alignment. I have the same front end set up. Billstein 5100 set at stock. Thanks for any input.

I know it has been a long time since you posted, but wanted to know the outcome. I did the exact same thing as you. Shitty Superlift lift/level and then 4 inch BDS lift this weekend. Shop cannot get the truck back in alignment especially with the caster. I think they got the camber and toe. I have a 2021 GMC Sierra SLT. 3.0 ecodiesel. Thanks.

A while back I had installed a Superlift 3” lift/level most and replaced Ranchos shocks with Billstein 5100 front and back. Yesterday replaced that with a complete 4” BDS suspension lift. Shop called me and said the rake from front to rear was a 2 inch difference. BDS had assured me I’d get the 4 inches with the Billstein set at stock. It should be no more than an inch of rake. the 3 inch Superlift did the same thing. my question to you guys is, has anyone lifted a 2021 GMC Sierra with the 3.0 duramax and got the correct amount of lift? if so did you keep your Ranchos or use different shocks? foe the life of me neither myself nor the shop doing the work can explain the rake difference after installing these kits. thanks for the help.

Thanks again. I am looking into it and Eibachs team is supposed to call me back. As of now, they do not have anything for the 3.0 duramax deisel. I was transferred to the tech guy who wasnt in at the time. But I will keep checking. Thank you again for taking time to send me the information and not being a d@#$ about it. Appreciate it. Out of curiosity, what are your thoughts on removing the spacers from the front and adjusting the Bilsteins B8 5100 adjustable right height struts up to 2.5 inches and keeping the 1.5 inch rear block in place? How much settling do you think would happen with that. Thanks.

Thanks and appreciate it. I just got off the phone with Eibach as a matter of fact. They do not have a kit that fits my truck because they have not tested their kits on the 3.0 ecodiesels yet. The Superlift kit that came had UCAs and they were replaced, I just didnt get the full 3 inches, more like right around 2 inches. Not a big deal, however when speaking with Superlift, they said it should have lifted the truck 3 inches as it is just spacers and they do not settle, which made me think maybe think it was the strut, but struts dont provide lift, springs do. But if Eibach had it I would have bought it. I will keep looking. Once it is time to get new tires, I plan on moving to a 4 inch BDS suspension lift anyways. If you have any other ideas about front springs and/or shocks please let me know. Both Superlift and Bilstein said to adjust the strut up to the one inch mark.

To be honest, the ride feels the same as the stock Ranchos that came on it. It rides great. To be honest i was hoping for a little more lift out of this 3 inch kit, but only was able to be around 2 inches instead of the full 3. I am thinking of moving the clip up one from stock to 1 inch to gain a little extra and get rid of the rake. Only keeping this set up till my tires need changing then going full on with a BDS 4 inch suspension lift. Just gonna use this for now.

Thanks and appreciated. I only ask because it is all installed and I did add the UCA that came with the kit. After getting all this information, I may just have the shop pull the Bilsteins up front and redo the coils back onto the stock Ranchos that came with the truck and put the 3 inch spacer that came with the Superlift kit back on the way it was intended instead of putting the Bilstein up a notch to one inch. Thanks for all the info. Now that I have done all this, I am thinking should have went with a 6 inch lift as that will be next I suppose. Thank you again for the information.

And that of course is another option I am contemplating. I am looking for 3 inches lifted and leveled thus the reason why I went with the 3 inch lift from Superlift. I had a 6 inch lifted SuperDuty.... If I did swap back to the ranchos, I would use the 3 inch spacers that came with the Superlift that I am using now with the Bilstiens. As for the ride, as you mentioned, I couldnt tell the difference between the Ranchos that came stock and the Bilsteins. So..... would it be worth it to put the Ranchos back on with the 3 inch spacers? Or adjust the Bilsteins an inch..... they are set on stock now with the 3 inch spacers and I only got 2 inches of lift so..... But thanks for the information. Appreciate it.

Thank you. How much lift did you get in the front? I just read I can get 2.75 inches total? Can either of you confirm your lift heights in the front and did you use a block at all in the back? What size?

Thanks. I was just looking at the Eibachs. Looks like they only go up to 2 inches? I am looking for 3 to add wider tires. Most of the trucks on custom offsets have rubbing when at 2 inches and wider tires. Thank you for the information. I am going to look at them more.

I added a 3 inch Superlift kit that came with Bilstein 5100 for the rear along with 1 1/2 inch blocks for the rear. I also opted for the Bilstein 5100 adjustable front struts as well. I wanted to get rid of the Ranchos. The shop left them on stock setting and I added the 3 inch spacers on top, however only yielded me a little over 2 inches total lift in front. Contemplating moving the adjustable ring on the Bilstein from the stock position to the 1 inch mark in hopes of leveling out the truck. The kit came with new upper control arms for the 3 inches of lift etc. They were added also. I removed the front and rear built in plastic mud flaps, added the running boards, hood visor, window visors and XD grenade wheels (20 x 9 with 0 offset) and kept the tires that came on it. 265 70 20 (33inch tall tires). Hope this helps with whatever decision you are looking at making.

I am new to this site as well as GMC trucks.... long time Ford driver but decided to make a change and move from a Super Duty to a 1500 and went with the Eco-Diesel. I know that when I post this, alot of you will say do not add a lift kit to the Bilstein 5100 Adjustable Ride Height front struts, a fact I did not know prior to the installation and calling Bilstein. Regardless, here is where I am. I added a 3 inch Superlift to my GMC that came with Bilstein rear shocks and 1 1/2 inch lift block as well. All of that was fine and raised the rear from 38 1/2 inch to 40 1/8ish stance in the rear. I added the Bilstein adjustable struts in the front, left them on stock level and added the spacers that were supposed to give me 3 inches of lift yet only yielded 2 inches (measured 36 1/6 inch height before and 38 1/2 inch after). The off road shop told me that when I bring it in for retorque of the bolts, they can adjust the front struct to the second ring which is 1 inch giving me the desired 3 inch front lift and leveling out my truck as well. I do tow a bass boat often and also added Firestone Ride Rite air springs in the rear to avoid the "sag". My question is really not can I add spacers on top of Billsteins, it is has anyone added suspension lift and not got the height that you thought, in my case I only got 2 instead of 3? My truck came with the X31 package and had Rancho shocks, wonder if I put them back on with the spacers would that give me the 3 inches to lift and level or just adjust the Bilsteins up one inch and in theory it should alleviate some of that rake and level it all out. My lift also came with Control Arms and other stuff to help with Angles etc. Any advise OTHER than dont add spacers with Bilsteins? Thank you. Here is a after lift picture as well. or just leave it with that built in rake.
