I'm trying to find out what model years interchange on the step-side beds. I have a 2004 GMC Sierra and I don't know what year model beds will interchange with it. I was told 1999 through 2006 but i'm not really sure. That means Chevy or GMC step-side beds.
If you have any idea what year models will interchange i'd appreciate it. I'm trying to locate an entire bed to replace the one on this 2004 that's destroyed.
Thanks.

I attached a document that I have used in the past that has proved reliable. I have not confirmed them on the step-side but others have proven out correct. It gives the measurements so you can confirm each bed that you find, if you would like to.

Let us know how this turns out. Thanks

Thanks. I think they were right about a 1999 through 2006 fitting as they changed styles in 2007. Now, i'm on the lookout for a bed for mine and also a power driver seat unit so it's going to be along road ahead, lol.

Hello, I'm Danny.

Just to add my 2 cents as a Silverado owner you can interchange any short bed fleet-side or step side bed from a GMC or Chevrolet from model year 1999-2007. There are direct bolt on.Also, there is a truck parts place in Kansas USA called LMC Truck that sells replacement bed patch panels. I've attached a picture below as an example of fleet-side patch panels that are available from LMC Truck. I know yours is a step-side but I just wanted to show you some possibilities that are available from LMC Truck.I know numerous parts sources for Chevrlet trucks.Hope this helps and thanks for using 2CarPros.

Thank you, Danny. I'll head over to their site and look around. I know I have quite a few things to change besides the bed or bed sides. Driver seat doesn't raise the bottom but goes back and forward and tilts the back, even blows up the lumbar. Just that one portion of the seat to raise the front or back or entire seat bottom up has me flabbergasted finding it. Maybe they'll have that and some of the other parts on my list.
This truck is a 2004 GMC Sierra extended cab step-side Z71 with only 105,000 miles on it so I want to build it back the right way and don't really like shopping eBay or Amazon.

Thanks a lot.

Yeah, I thought the 2011 year sounded off for that document but it’s been right to this point.

This is one of the most most common trucks on the planet so parts availability shouldn’t be an issue.

Good suggestion of LMC Danny. Let us know what other info you need and if you need more help on that seat issue let’s get a post started for it and we will help out. Thanks
