So i put my RC 2" level kit and Toyo 295/55/20's on this weekend. Install was simple, just like on my 2011. It definitely helps to have an extra set of hands when wedging that spacer in there. 295/

Thanks. Here is one more from yesterday. Considering we're getting 8-10 inches of rain the next two days, I won't be taking any better pics soon.

Mine is finally done! After months of research I went with the RC 2.5" level kit front only, stock rear block. 20"x9" Fuel Nutz w/ +1 offset, 33x12.50x20 Toyo M/T tires. No rubbing, No trimming, yet a

Hello All,

 

First off, I want to say thank you to everyone on this forum, for all your research, information and pictures. It made my effort on the modification on my truck much easier. I have taken many pictures and tried to get as much details about before/after in ride height and fuel mileage for everyone. I hope this helps everyone who is looking at doing the same. My truck had an almost 4” rake before the level, which drove me nuts and the low ground clearance in front, were the main reasons I added the level and larger tires. Absolutely love the way the truck came out, would do it again in a heartbeat.

 

2014 GMC Sierra Crew Cab SLT All Terrain 5.3L Short Bed

Level Kit - Pro Comp 2.25” level

Tires - 275/60/20 BFG A/T KO2s

 

RIDE HEIGHT

Before (measured from the ground through the center of the tire to the wheel well):

Front - 36”

Rear - 39 ¾”

 

After (same measurement technique):

Front - 38 ¾”

Rear - 39 ¾”

 

Pro Comp 2.25” Level Front end only (nothing done to the rear). I went with this kit instead of the RC 2.5” because it seems to be of a slightly higher quality material and I didn’t know if that additional .25” would make it look too tall with 275/60s.

 

I measured multiple times before to ensure accuracy, as well as multiple times after. Yes, I thought was a little odd that the rear didn’t come up since the new tires were just over a full inch taller, but seems this isn’t the only case. Front came up exactly 2.25” + 0.5”. I adjusted the headlights slightly after because they ran a little high, easy adjustment.

 

RIDE QUALITY

Before the level kit and tires, this truck rides great, especially for this large of a truck. It was incredible quiet and surprisingly soft. After the level kit and tires, there is a very noticeable stiffness in the front end now. By no means is it too stiff, but coming from how soft the stock truck is, its a much firmer ride. (I have gotten use to it since the initial drive from the shop). I am sure this is a combo of the level kit and tires. Being a firmer ride, I would argue that the truck actually handles turns better now with the firmer setup.

Sound - The level kit I wouldn’t imagine would have any difference in road noise, maybe wind noise as it sits higher, but with the new KO2s, you can hear a little bit of a buzz on the highway over stock (stock tires are incredibly quiet). Most people would not even notice, especially if the music is on.

Acceleration - These new tires (BFG A/T KO2s 275/60/20) are much heavier than the stock Goodyear Wrangler SR-A (275/55/20), and you notice it immediately. Again, nothing you won’t get use to with time, but right after they were put on, accelerating off the line it is noticeable that these tires are in the range of +16lbs per tire. This plays into MPG below.

 

MPG

Before I was in the range of 17 CIty and 22 Hwy. After the level and tires, I am in the 15 City and 21 Hwy. When I am going just around town in traffic, it can easily be in the 14 mpg range. On the highway, I haven’t noticed that big of a difference each drive is a little different and it’s in the 0-2mpg range. (Don’t have many really flat hwys where I am)

 

TIRES

Had the stock Goodyear Wrangler SR-A (275/55/20) previously and they are great highway tire, but terrible off road and in bad weather. I wanted to go with a good all terrain tire that I can take off road, use in the snow and still be on an everyday truck. I was originally going to go with the 275/65/20 KO2s but were out of stock and it would take 3 months to arrive, and I was getting a super deal, so I went with what they had in stock, 275/60/20. The shop I went to said there is a small chance the 65s would rub a little with the Pro Comp 2.25” level, so I decided to play it safe, and cheaper with the 60s. (Plus the 65s would be even heavier and higher load rating) They fit VERY easily, not even close to rubbing anywhere. I will probably go with the 65 series when these wear out for a little extra height and the look. So far I have had them on city, hwy, snow and light off road, and they have been great.

 

 

 

Just a quick update here....... I removed that worthless front air dam...... It looks 100x better in my opinion. I have seen virtually zero MPG loss (maybe 0.5mpg, but that can very easily be driving style/conditions). The front air dam is for sure staying off.

 

ALSO - Interesting note, I went back to the shop that did my installation of the Pro Comp leveling kit, as I heard a few squeaks here and there. They said everything was fine (shocker) and they didn't notice anything. BUT, they did re-tighten everything. The truck ride is MUCH better now, basically back to stock - I initially said the truck rode firmer after the level, which is did, but now it seems like it is back to original. There was definitely a difference before and after they re-tightened the suspension components after about 1000 miles on the new kit. I would recommend this to everyone.

 

Pics below without the front air dam. Also a little fun in the snow, tires are awesome.

Great write up! You put a great deal of thought into this project. You took some careful before and after measurements and recognized a potential problem of going 1/4 inch too high. This has been my concern as I do not like a squatted look, even when carrying cargo. To make sure my truck maintains a little bit of a rake, I plan to go with a 1.5" level. The problem I am having is that I have close to an inch difference in height at the back of my truck. The lower side is the gas tank side which I usually keep full. I am going to run it to empty to see if this is the reason. I am wondering with all the measuring you have done if you noticed a discrepancy from side to side.

Here's another picture. As to why well I'm from California and here it's a style. What works for us might not work for others and what works for others might now work for us.

I too am from California and am partial to the lean. I leveled mine front only and was thinking about removing the rear blocks. Its crazy how different the angle is on those two pics. Makes me think removing the block wont even make a difference lol

I have the same problem. Hopefully u can figure out how to level the back of your truck and let me know.

Here's a shot of my 2016 GMC Sierra Z71 SLT. I had the Ready Lift 66-3085 2.25" suspension lift installed. This pic is of the before the shell and after the shell installation. The leveling kit leaves the truck with a slight rake that is only really noticeable because of the step assists rails on the side. Measured the front and then the back (of rails) and there is about a 3/4" rise. I am good with rake and thinks it looks much better then stock.

 

How are the headlights doing now that you got the lift in the front?

Mine is 3/4" off....driver side lower than passenger side. Very common and attributable to the gas tank. I tried to level mine out by increasing the air pressure in my air bags on the driver's side higher than the passenger side, but it just raised the entire rear up higher. It bothered me at first, but I don't even notice it anymore.

Since the back sits a tad bit lower, it does make sense to lower the headlight angle a bit. pretty easy to do. clockwise DOWN counter clockwise UP

Sorry, yes a 1.5" motofab leveling kit. I'm running stock tire size right now, but have Hankook Dynapro ATMs. I'll probably go a little bigger next time I buy tires. Now I'm looking for some rims to match my new side steps.

Any rub with this set up

 

Just wanted to let you guys know for those considering 35s...

 

They fit on factory 20's with minor wheel well insert trimming. It was worth it to me, so I did it. Very happy with the way it turned out.

 

I still rub slightly in reverse at full lock, I could probably remedy that with some additional trimming but I'm not sure I care at the moment.

 

I'll upload pics later for anyone who wants to see.

 

Setup:

 

2014 Sierra SLT 4x4

Pro Comp 2.25 leveling kit

Toyo Open Country M/T 35x12.5xR20

 

 

I'm still on the fence on getting a bigger lift. Not sure if I want to void any warranties just yet.

Robvas do you have any pics of your truck? I'm interested in a level kit also, I just bought a 2016 1500 GMC SLT 6.2 Max Trailering Package. Thanks.

      Towing In Loose Gravel

      By Z45 · Posted

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses more gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.
