2006 Ford E350 - Sportsmobile 4WD manufacturer?

[appalachian_american]

Sportsmobile doesn’t know who manufactured 4WD system. Need to replace suspension parts including leaf springs Don’t see any badging. Anyone know or suggestions welcomed.
Cost and advantages to switch to a coil over?
Thanks!!

You can contact Field van or SMB if you know which one did the conversion for the build sheet.

Leaf springs are tried and true but if you need to replace the front leaf springs there are several outfits that do that. Ujoint does a coil spring conversion. 4x4 Conversion - Looking for advice (Pros/Cons)

What front axle do you have?

Best to contact Chris at U-Joint to confirm, but I believe they don’t convert leaf to coil anymore themselves - think they only sell the DIY Kits for that application.

Thank you! Dynatract front diff. Solid axle, no branding on it. Atlas II transfer. Shop I had balance driveline said custom. My E350 is small in their work. Orig sale was in Cali. SMB no help. I’ll call Chris & keep digging. I’m in Pittsburgh. Needs many bushings replaced. Stay tuned, thanks again & enjoy the long wknd!

That's a sportsmobile 4x4 conversion with Old Man Emu springs. Rear are stock. The leaf springs were lame and would reverse arch. Lots of folks in this forum went with Deaver Spring upgrades.

If you stay with leaf springs and the same sway bar you'll want these: Ford E-Series 4x4 Front Sway Bar Quick Disconnect Kit

Betts makes nice springs.

SMB is the only one who did conversions using Dynatrak and Atlas. If they don’t have record of converting your van, a previous owner maybe did the work themselves using parts off a wrecked SMB.

Thank you Joe/all. FieldVan confirmed they did the conversion. Buying all the replacement components through them. More difficult than I have patience to find other options. Appreciate the help, very much.

If you're replacing suspension parts, and since it doesn't seem you have any of the Sportsmobile Binders, you'll also need the alignment Spec's (or the van will drive like crap - this was my first mistake as a new & naive owner).
I have a 2006 6.0 and would gladly send you a copy of my spec sheets, but if you have a different power plant I don't know they'd be the same.
