Hey guys. New here to the forums. This may have been discussed... I have looked through some pages and honestly cant get past looking at the pictures of all the awesome trucks builds! I have a 2014 Sierra 1500 4WD Crew Cab. I want to level the truck by lowering the rear. I don't haul anything heavy or tow. However, I have to remember Mom & Dad need to get in sometimes. :lol: I was told removing the stock blocks under the leaf springs would level it with the front. Is this true? Or, is the better option to buy the lowering shackles? Thanks in advance!

Level up the front and get steps/running boards! :)   personally I would never lower a 4wd...but thats just me...welcome to the forum, good luck with your truck!

Installing a 2" RC leveling kit this weekend on my 2016 Silverado 1500.  Does anyone know if 285/55R20 BFG KO2 on stock wheels will fit with little to no rub?

 

Or maybe the better question, what is the largest size BFG K02 I could run on stock 20" wheels with a 2" RC leveling kit? I'd prefer to stay away from large wheel spacers if possible.

Should be pretty safe with 285/55/20, you could maybe go up to 295/55, but you’d probably have to do some minor trimming to get to zero rub.

285/55 should be fine, I wouldn’t go anything above that though. I’m on +18 wheels and 285/55r20s with a 2.5 level and I can tell you too much bigger and I would rub. I still want to do some testing because I feel like I feel rubbing at full crank but it could just be the knobbier new tires I have now causing that sensation.

I can tell you a lottt of guys will tell you no rubbing or little rubbing on the more aggressive set ups aren’t telling the full truth. If I went with a more negative offset on these it would rub for sure, and they aren’t too much bigger than stock. They definitely look great though, I can’t tell any difference really looking at these and 33x12.50 on friends trucks. Same height just a tad narrower.

the 285/55/20 is actually slightly shorter than the 285/65/18...both will fit without any rubbing with a 2'"level up.  as far as the largest...you are getting pretty close to that (without some little mods)...

 

i believe they make a 275/60R20 now....and i would think that would be the ideal and perfect fit...BUT that would probably take a little trimming of the carpet wheel liner, but that isn't a big deal... others might have a better answer for you...

I'm not a fan of lowering trucks.....but the rear block is 1.25". So, removing that will lower the rear 1.25". Most trucks have 2"-2.5" of rake, so you probably won't end up exactly level...but you'll have less rake than you do now. I'd say try that first, and see how you like it. You could always add a small leveling kit to the front in the future if you wanted. That being said, trucks that are "exactly level" have always looked nose-high to me for some reason.

285/55/20 should fit without any trouble at all. In fact, they'll probably fit without any lift at all. If you're wanting to run BFG AT's, then I'd recommend the 275/60/20 because of the extra height. They should fit fine with a 2" level.

So I have the 2.5" kit coming tomorrow. The step that uses the 21mm wrench...can I use a 21mm socket? I have the socket but not the wrench. I have all the other tools. I can buy a wrench if needed, just would rather use what i have.

for removal with a deep socket yes... for reinstall if the ball join spin you wont be abble to hold it from the bottom with a 10mm wrench

Put the level on last night. It's the steering linkage that uses a 10mm wrench (if it spins while reinstalling). The ball joint is a 7/32 allen for those doing this in the future.

 

On a side note, it was late so I didn't put the rear block in. Like a dummy I didn't have all my tires inflated to the same PSI so my initial measurements were off. Now the front is higher than the rear. Tires are all the same now, and as soon as I add the rear block I'll post up pics and measurements. Thanks for all the help so far guys.

I have a 2018 Seirra Denali 1500 with a 6.2 and added a RC 2.5” leveling kit. With leveling kit in and when 4 wheel drive engaged it have a pretty good vibration when engine is under a load. Anyone else have this? Take leveling kit out and it goes away. 

Finally got all my issues fixed. 90% of my problem was in front driveline. Brought it to a drive line place and there was a curve in it. So much so they wouldn’t balance it. (GM) says it’s within range of normal ?. Had them build me a new driveline. The other 10% were in the tires. I had 295 55 toyo. Went to a 285 55 hankook and all my problems went away! Was thankful the dealer picked up entire bill except tire exchange. Just thought I would throw it out there if anyone else comes across this. My dealer found another truck on their lot with same drive line issue after I told them about mine.

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!IMG_20180407_104530.thumb.jpg.6eb1d241e09b4bd3e72ce2b59efa2438.jpg

That looks great.   I've heard you can run 1" spacers without trimming the studs if you have the pockets in back of your wheels.  

 

They are 20" rims on your truck, right?

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.

I have a 2015 GMC Sierra 1500 Z71 4x4 Crew Cab all stock with 265/65 -18 inch Wheels/rims. I was wanting to raise or level out the truck, but still want a slight rake for payload. I don't want the front higher if i put anything in my bed. I have read many forums comparing the 2 inch RC in the front vs the 2.5 inch level RC changing the front and rear. The only discussions i have seen involve non z71 trucks.  For those who have a z71 truck which one do you prefer?

 

My plan was just to do the basic RC 2 inch level in the front and go with 285/65-18 tires, but would hate for the nose to be too high. Should I stick with my plan or go to the 2.5" or find a 1.5" level in the front. Thank you

    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?
    • That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?
    • That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?  
    • Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
