Looking for wheel well height on stock 1500 AT4.

If you are “leveled”, what are your heights?

 

I just got icon’s “leveling” kit (1 1/2-3 1/2” adjustable), WITH the Icon rear shocks.

I made the mistake of not checking stock measurements before install.

 

My heights with Icon level are:

front right: 41”

front left: 40 3/4”

 

Rears: 40”

 

Truck is going back to 4 Wheel Parts to lower the fronts.

AND, at these heights,  the truck is NOT happy driving in AWD mode, especially on acceleration.
 

Thanks for any help.

The front is about the height that mine is sitting after the Icon kit. I do not have an AT4 or trailboss version, so unfortunately I am now squatting quite a bit in the back. I am going to put 2" rear blocks in the back to fix the squat.

 

What is your truck doing when in AWD? From the install I have, all the CV and upper control arm angles look great, better than when I previously had a spacer kit. Is it not letting you go into AWD, or is it making some kind of noise? Im interested incase mine does the same. I have not tried this setting yet since the install.

 

Thanks.

2” block will help you, but it still may sit nose high.  It all depends how high they cranked the front up.  Your front wheel well should be no more than 40” to stay in Icons recommended range.  The Icon front strut is adjustable from “1 1/2 to 3 1/2”, but it will also adjust higher with more turns, hence putting stress on CV angles, etc….

At this moment, I think 4 Wheel Parts has it cranked up 4 to 4 1/4 inches…since stock non AT4 height is 37”.  I’m at 41+.

And I’m already getting excessive wear on the outer edge of the right side front tire.

1200 miles on odometer.
No bueno.

 

And…

When driving  in AWD mode it makes a VERY strained sound upon heavier acceleration.  I read somewhere on here that the excessive lift could be stressing the transfer case, differential, CV axle, CV joints, but I don’t know what that means…I know nothing about suspensions. 😞

I just don’t know what the fix is.

 

I only drive it in 2WD mode for now until I get the front lowered more, and hope it resolves the problem.

Keep us posted on here, I would like to know what 4WP has to say.

One more question, where did you find from Icon that the front wheel well should not be more than 40 inches? Wouldn't the size of your tire have an impact on this number as well as the amount of adjustment on the shock? If you had 35's you would be up higher than 33's, etc...

Yes, you are correct…for me…with stock tires…I need to be no more than 40” to be level.  Larger tires changes everything.

My bad.

i just assumed incorrectly that we were talking stock tires. 😉

  • Looking at the ICON web site most of the kits have a little footnote that states the adjustable lift height for the AT 4 is 0" to 1.5" , not the 1.5 to 3.5 (regular trucks) Could it be cranked up too much?? Also have the installer check how severe the front axle angle is.

      How many miles were on the truck when you bought it and was there some form of oil change history generated through a dealer or an independent shop although not much would show up if the owner had changed their own oil. Just curious if it was a maintenance issue or if there was something off from the start, surely one would think the original owner would have realized it was using a lot of oil, its hard to go back in time and find out the true story of mysteries like this. Well hopefully the warranty company will go for it and just install a new engine, that would be the ideal outcome.    I still have so few miles on my truck as per not quite 9000 and will be changing the oil shortly which has around 2700 miles on it or so and its down so little on the dipstick from where it was at the beginning of this oil change that I could make the "claim" that it uses no oil but in reality would be a very small amount, less than a 1/16 of an inch. Just driving empty/not towing and easy driving so hard to say what it would do if it had a load behind it for oil consumption. So far very impressed with the very minimal oil usage.

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
