Rear Spring Conversion

Has anyone converted their '99 to '07 truck to the longer '08 rear leaf springs?

I changed mine out but not for stock ones. I had a company here in WI custom make me some. They make leaf springs for train cars. For $400 plus tax out the door I got a brand new set of springs with bushings. They said they are not quite 1 1/4 ton. I say they are one ton so I dont get the itch to put more weight than I should in the back.

no iirc there was an issue with towing trailers on the 08 were the back end sagged a little to much. I could be worng on that though.
either way not a hard thing to really do cut rivits off of purches and relocate them to fit the 08 srings.
I will say punding out frame rivits is a pain.

So the procedure is to relocate all four spring hangers to accomodate the longer springs for a better ride. Is that the correct understanding as for everyone else as well?

Why not just add airbags? That made a huge difference in my '06 and the kit was no drill.
