Headlight Adjustment on lifted HD

I recently purchased a new 2020 2500HD LT Z71 from the dealer with aftermarket 5” suspension lift and 37” tires. I decided to replace the halogen bulbs with aftermarket LED bulbs that work great, but I blind everyone I pass. I tried calling the dealer to inquire about headlamp adjustment, but they told me to contact the place who lifted the truck. That place said they had never received a call like that and headlight adjustment wasn’t a part of the lift kit. I was inclined to adjust on my own, but it seems the standard headlight adjustment screw doesn’t exist on the 2020 2500HD. Has anyone with left/level been successful at adjusting the headlamps? I got pulled over yesterday and the police officer said he would cite me if I didn’t get them adjusted...

Been searching for it but can't find it...but it might have been a GMC...

So the dealer should be able to adjust it if u have to contact them.....I would take the manual into them and show them.

really the dealer should be responsible....they sold you a brand new truck  they put the lift on and charged a pretty penny for sure....it has warranty and should be sold just like any other factory vehicle....not to mention you just spent 60-70k at their place of business.....that's the route I would be taking....

 

than begs question did they calibrate the steering, etc....

 

they should take care of it without hesitation.....if you mentioned this prior to signing they wouldn't even hesitate, or they would just lie, lol

Problem is the headlights were upgraded

Does the original bulb have a black deflector at the tip

Yeah I’d def make the dealer do it. It’d be one thing if you did the lift but since the dealer installed it they need to fix it.

With that being said, you may have to put the stock bulbs in and see how far off the aim is for them to adjust it. Some bulbs aren’t meant for halogen reflectors which can cause the glare. HID’s for example will blind everyone with halogen reflectors even on a stock vehicle.
LED’s can have a similar affect, just depends on the bulb.

Over the weekend I had my snowmobile in the back of my truck and got headlights flashed at me on a two lane road, with all stock halogen headlights and LED fog lights. The truck had about 500 pounds in the bed, so not very much, and the headlights are already getting to high. That did happen with my trailer hooked up with about 800 pounds of tongue weight. I really think the LED fog lights are the issue, but should drive my wife's Traverse while she drives the truck just to check. There has to be, or should be, a way to adjust both sets of lights.

Thanks everyone! I finally found the screws! Yes, the same screws just like the 19 and older models, only the placement is about 12 inches down, just behind the lamps when you open the hood. Since my truck has the lift, I wasn’t able to get a good look down in there without a ladder, and the dealership was no help - I’m guessing they haven’t had to work on these much yet since they are still relatively new? Once I found it, just a couple of turns clockwise and I was back in business. I did the standard 25’ method for good measure and no more blinding oncoming traffic!

 

thanks again....

Up here in Alberta, Canada I was pulled over because I had my fog lights on when a vehicle was approaching (i.e. a cop car).  Supposedly not allowed to do that, they have to be turned off the same as high beams.  Maybe that is why you were being flashed.

You put LED's in a housing not designed for it, you are going to blind everyone regardless (though at least you are making an effort). LED's are way brighter than the standard output just like HID's and exactly why they have specific housings for them. Do it right, get an LED housing, oncoming traffic will appreciate it (especially that old person driving towards you on a two lane). Otherwise you are going to look all fast and furious like this with extremely bright lights just scattering all over...

True, not the adjustment it's the bulbs.

With Spring right around the corner local LE apparently have been using aftermarket lamps as a reason to stop vehicles to see whose been naughty and whose been nice. lol

I don't believe that is a law in Michigan. I would say over half of the vehicles on the road drive with their fog/driving lights on with their low beam headlights. It is impossible to use the fog/driving lights with the high beams, which I think is a stupid configuration.

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
