2024 LED/LTZ front end SWAP!!!

[feedthebob]

I hated the holagen front end since the day I bought my truck. I looked all over the internet for someone who had done the LED swap but couldn't find anything besides people asking about it or people saying it's been done with no pictures or info to back it up. Used parts for the 2024s are becoming more available now and I finally gambled and bought what I hoped I needed. I found both headlights, the grille and an upper bumper fascia all on ebay from salvage yards and bought the harness from gen5diy.com. that's all you need.

 

Take off the top grille/vent piece under the hood, just some plastic clips.

 

Take a few screws out of the front of the fender liners, about to the center of the wheel well.

 

Pop the wheel well trim off to about the same spot (more plastic clips).

There's one tiny screw (7mm) where the bumper fascia meets the fender underneath the wheel well trim.

 

The bumper fascia then pops off, lots of little clips so you have to go slow and work your way across it with a bunch of gentle pulls.

 

The grille then has 4 10mm screws on the top and 2 in the bottom corners. Then more gentle pulls to pop it off.

 

Lastly the headlights have six 10mm screws around them.

 

There's some videos online about removing grilles and what not that helped me some. I ment to take pictures or record the whole process but I got on a roll and kinda forgot. I know I would of really loved this information a few months ago so hopefully I'm helping someone out by sharing.

Looks great, nice work! Did you have to get any special harnesses or anything to get the LED headlights to work properly?

Yes, I had to get a harness from gen5diy.com to make them work.

This is the one, it says specifically for 2024-2025 hd trucks switching from halogen to factory LED headlights. So far everything works as it should. Auto headlights, drl is the white led strip and it turns to amber when turn signals are on. Same hood, same fenders, same bumper. Just have to change the grille and the bumper fascia that runs under the grille fender to fender.

Lol i spent so much time looking this up and found pretty much nothing, that's why I wanted to post this. I do know the 23s are different.  Gen5 has a different harness for them and I know the front bumpers are different. I'm not sure about anything else. That picture looks cool though

That would be cool, I'm pretty sure the bison bumper is just an AEV bumper for 2500s

By chance can anyone dig up part numbers for said parts?

This is from the bumper fascia. That's all I got though. Headlights are easy, I believe they're all the same. Grille just has to be for an ltz or high country

I might have been one of those that was talking about doing it with no pictures. I'm wrapping up doing the front end swap on my '21 Midnight. I built my own headlight harness, but didn't need a relay like the Gen5 harness incorporates, so I don't know what they're using it for. Anyway, yours is looking good.

Bro thanks mine is a 2020 high country it already has the led harness i believe should it be the same for the 2024 headlights? And you only bought the headlights,grille,fascia bumper ? That was it the hood is the same?
