RCSB 2WD 1500 LMM SWAP

I am new to the forum and I am just starting my RCSB 1500 2wd LLM Duramax swap. I will try to keep updating with pictures along the way. I searched the forum and found a lot of information. Any “helpful” information will be appreciated. The donor is a 2008 Silverado 3500 cab and chassis regular cab 2wd. Cab and engine will be swapped onto a 2012 RCSB 1500 2wd frame. Just picked up the frame today , had the Dmax for a few weeks. First thing is to clean and paint the frame then start the swap. Any help or suggestions would be greatly appreciated. Please don’t comment negativity, this is my build and have been wanting to do this for a long time. I value everyone’s opinions but please don’t keep telling me to use the 3500 frame and cut it down, that’s not what I am looking to do. Thanks and talk to you soon.

You may wish to also swap in a beefier rear end to go with the duramax. The 1500 diff likely isn't up to the power the duramax can put through it.


Looks like a fun project.

It has 380k miles on it but is a southern truck and very clean. Don’t have history on it but is was very well maintained. You would never know it has that mileage on it.

Brought my son to the shop today to help get the cab off of the short bed frame. Cleaned and painted it up, it is in really good condition. We had a great day and it is now ready for the swap. Got to teach him how to use tools and work with his hands. Next weekend we are gonna do the swap.

Don’t know why some pictures are sideways. Is there anyway to fix them?

I believe It has to do with space available within the post.
Try upload fewer pics per post
