Here is the all inclusive way to swap a GMC K2xx 1500 front bumper to a 2500 Front Bumper. This is for the Sierra only, the Silverado is/may be different.
First lets start with what IS needed the part numbers if applicable.
HD Grille (PN Varies )
HD Bumper assembly (PN varies)
HD "headlight fillers"( GM list's them as 'Top Cap Assembly)
--------LH PN 22831429 Paintable
--------RH PN 22831430 Paintable
HD headlight filler brackets ( GM lists them as Fascia Bracket assembly)
--------LH PN 23451021
--------RH PN 23451022
****I will also mention the Front bumper to inner Frame support brackets. I got them with my 2500 bumper when I purchased it, so I used them, and they work and fit great. Im sure but cant say for certain if the 1500 bumper for frame supports can be made to work.
Once all the swap parts are acquired, then you can begin modifying the parts on the current truck
The 1500 Bumper mounts have to be used. I attempted to try and use the 2500 brackets and the mounting holes are in the wrong location, as well as it makes the bumper sit way too far forward away from the truck,
As for the 1500 modifications, the 3 mounting holes will need slotted so the bumper brackets can sit lower to accommodate the additional height of the new bumper. Reinstall the brackets and drop them down until they hit the frame. ***** I spaced my brackets up a bit off of the frame. I felt the gap between the headlight fillers/grille, and the bumper was too much. with a little spacing you can get the gap nice and tight*****
I also used 3 additional washers behind the brackets to space the bracket away from the frame. With out the additional spacing the bumper sat too close and didn't align in the wheel well
Once the frame brackets are situated, you can move onto the fascia brackets. they are a simple swap, unbolt the 1500 and swap them for the 2500 brackets
Now install the headlight fillers onto the fascia brackets that were just installed. The headlight filler assembly's will also use a bolt location from the 1500 grille that the 2500 does not use.
Now its time for the bumper. Install the bumper onto the frame brackets. The 1500 brackets will only allow the Upper hole closest to the grille to be used for attachment. The Bumper will fit pretty tight onto the brackets. As I said earlier I was able to use the 2500 Inner bumper to frame brackets , they were the correct length, and shape to fit around the frame Mounts
The last big modification is the fender well trim. The 1500 trim is much longer as shown by the blue tape line. The trim needs cut on the bottom of the tape to align with the headlight fillers
When it’s all said and done the top pic is the OEM 1500 Denali and the Bottom is the 2500 Denali Swap (yes I know the fog lights aren’t in but I was excited to take a pic)

Hi I’m new to the forum, so pardon any incorrect etiquette on my end.
I have a 2014 Silverado 4x4 with aluminum LCA’s. After doing about a weeks worth of troubleshooting a loud squeak when turning the wheels, I did some investigating and learned that I most likely needed new lower ball joints. I ordered up some MOOG LBJ and some new tie rods as well. After the GRUELING process to get those ball joints out, and replaced, a week later... I HAD THE SQUEAK STILL. I look to the ball joint again, and the grease was spilling out of both of the brand new MOOG lbj boots.
Listen... I’m not against saying that I might have been rough and ripped them upon installation... but at this point, I don’t care. So I ordered some brand new Lower Control Arms with LBJ’s in them already.
Now finally, my question. Is there a way to install these Lower Control Arms without removing the entire wheel/hub assembly all over again? It looks like there are 6 bolts. I’m going off of memory. I have King OEM shocks that I’ve taken off countless times, so I know those are easy, I’m just looking for a quick way to get the job done.
any help, helps!
thank you for hearing my terrible story haha
I'm new to the game. I understand tire sizing but not fitment regarding clearances with aftermarket wheels. Looking for some advice. I know that I would like an aggressive MT in 33's. I'd like to get new wheels because I absolutely hate the stock polished aluminum 18's I have right now. I'd like to get 289-295/70/18's but I'm not sure if that would fit with wheels with a -24mm offset and still have enough clearance in the wheel wells to turn completely without rubbing. My plan is to get the MotoFab 3 inch front leveling kit (strut spacer) before I go and by wheels and tires.
If you've done something similar, I'd love to hear form you. If you know of a good way that I could figure this out without buying everything first to test it, that would be great too. Thanks in advance!
Quick update: I've spoken with a friend of a friend who knows WAY more than myself about lifting trucks and the fitment of aftermarket wheels and tires. First off, he suggested that I don't put in a 3 inch strut spacer kit. His reasoning was that I'd be replacing ball joints, CV shafts, wheel bearings, ect. His rational was that the spacer would through the angles off too much and put excessive wear on many parts. He also said I could go through and change out the upper control arms to attempt to correct the angles a bit (at that point, I'm thinking, well if I'm going to go that far I might as well just wait and buy the real lift kit that I want). Another point he brought up is that if I were to put the 3 inch spacers in, it may through the alignment off so much that there wouldn't be enough adjustment in the stock tie rods to make the proper adjustments needed to complete the alignment.
So now I'm just in the process of re-evaluating what I want to do. Stand by for another update soon to come.
I finally bought myself a big boy truck after owning a lot if sports cars and a Wrangler. Found a smoking deal on a new 2020 Silverado RST Z71 with all the options I wanted. I've never been so pumped for a vehicle, it's the first new vehicle I've bought myself. Cheers Gents!
