Just do it yourself. Then you can do them the way you want. I let the dealer do it because I wanted them to check the alignment cause after 600 miles I felt it starting to pull. When they readjusted the headlights they aimed them all th way down. So the cut off line was on the ground 40 ft infront of the truck.

If you do it yourself the adjustment screw is in the center on top of the headlight. You will need a Philips or Alan key.

Mike , thanks again for the info brother.

Do I have to pull anything off or will I see it and adjust from there ?

that is odd, since there wont be a lift, what if I left the level kit upfront and just ran these with it? possible? im thinking the ride would still be better. and if it doesn't lift it wont throw the front end any higher and mess up the angles.

I saw the same thing Bub...I have a LTZ z71 and was looking into the Quick lift also. I have an email into Rancho. Waiting for reply.

let me know what they say. I ordered anyway in pairs. I can put the rears on if the fronts don't work and return them. but that makes no sense, my front end looks just like my buddies regular 4x4. its no higher.

ive also read through some other forums and threads and seem someone else had them on a Z71 and did it. so im curious now as why it wouldn't lift

Just need to pop the hood and you'll be able to see it.

I have to adjust mine down after a 2 inch. I don't like it how it is now.

Funny , the local led bulb guy who works as a one man team wanted $50 to re aim.

Love this forum for this very reason ,,,everyone has some info on a truck we all love

I'll be getting my 2.5 RC front only Thursday with 305/60r18 on stock wheels, I've seen posts where some say they will rub and some say they won't anyone know for sure?

I have a 2.5 inch level and those are the tires I want as well. I've heard that some trimming is needed, but maybe someone that has this setup will chime in.

Here's my bone stock 2015 Sierra All-Terrain "before" pictures for reference. Plans are 2.5" RC kit up front, gonna leave the stock blocks in the back. I'll swap for the RC blocks if I have less than 0.5" rake or looks "nose high".

 

It's also getting 295/55r20 (33x11.5) Toyo AT2 Xtreme tires on stock 20's and black Bulletproof offset mud flaps. Should be done after the weekend, I'll report back with "after" pictures and measurements.

Here's a little bit of an update, got the Rough Country 2.5" kit installed up front and the 295/55r20 Toyo AT2 Extreme tires on.

Decided to leave the stock blocks in the back for now, had the shop send me a couple pics and take a few measurements.

Currently sitting at 39.5" up front and 39.75" out back from ground to center of fender.

I'll give it some time to see if it settles and if I change my mind I can easily swap the rear blocks.

Just have to get the BulletProof offset flaps on, tint the front windows and get the front bumper PPF installed.

My stock Hollander 5308 wheel are 8.5 wide. Can you tell me what width those stock GMC wheels are?

    • Can anyone explain why the oil pressure runs higher after the DFM is shut off?  just installed the Pulsar Lt.
    • Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.    
    • not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...
    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
