Anyone move their springs under the frame?Thinking it could help with articulation.Blazin:rasta:

I was thinking of doing this for a 1/4 eliptical, I think you would end up getting a lot more twisting in the springs when you articulate by doing this. It might not hurt anything, but it's a factor to consider. How far in are you talking?

"Fullsizes Rule" did that with an F350 trail rig and it works very well. Used semi-ellip moved under the rails with long shackles in the back. Flexes very well and seems quite controlled.

There are a few pics of a guy in our club SoCal Big Dawgs (http://www.socalbigdawgs.com) that has inborded springs on his red 73 Blazer. It got a 1200 on our 23* ramp. His name is Chris. He was in the voting for the TTC but didn't make it.

BTW:
Mine is the yellow one:p

yes it does help articulation at the expense of stability, it also helps articulation both ways equally (more or less) so the tires will both stuff furthur and droop more, I don't know if that matters but if you have fender clearance issues it may

I was thinking of putting them directly under the frame in the rear only.Not the front springs.So probally like 6" overall.Does his rig stay level in the rough stuff or does it lean alot? I want to tub the rear also and put a jeep rear seat in back for the kids.So wheel clearance is not an issue.Have sazalled everthing allready.Blazin:rasta:

Actually, the F350 seems rather stable for the most part, even with tons of flex. No more lean than most other trucks on the same grade. I've considered (and he suggested) doing the same thing for mine. I'm waiting to see how my reversed F150 spring work out though...

I did it on my 82 K3500. Moved the stock springs under the frame rails, pulled out the thick bottom leak and gained about 4" in height. I tubbed the bed and was able to fit dual 15x36 Dick Cepeks on both sides. I guess it's got more articulation, I never compared it to the stock set up. It is stable (even with a locker) and that's with a lot of freeway miles and winding roads going to the mountains. I did have to use it about 2 years ago for work (contractor). I put a lumber rack on it and loaded it up. Now, that was quite a bit different than stock! You were reminded the springs were moved in every time you went around a corner with a load on that rack! It leaned! But, that was the only time I ever noticed it.

One of my club members is doing a 3/4 ton pickup cab on blazer frame flatbed thing with flipped shackles in the rear, if he can find a fuel cell that he likes he is going to ditch the rear tank, bob the frame at the shackle hanger, and flip the shackle hangers and front spring mounts to the inside of his frame - a very long ways I know, but it just might work, should move his spring pads in about 7 inches on each side. I've got lots of old frames, so we may mock it up first before we take his spring hangers off.
