I have a 1985 W350 crew cab with a complete Cummins conversion from a 1992 W250 donor (including the Dana 70). My donor vehicle did not have the factory overload spring option, which i would like to add to my truck.

Would anyone happen to know the factory part #'s on the springs, and the perches which mount on the frame (the rubber stops)? I'm wondering if these are still available from the dealer??

Thanks!

 

I looked on oemdodgeparts.com and saw that they're still listed. It doesn't give part number, but if I can look it up there, your local dealer should be able to look it up in their system. The 4 leaf aux spring lists for $127 each, $87 from oemdodgeparts.com. Doesn't show the brackets, though.

I'd go look in a junkyard for them. Lots of 3/4 ton and 1 tons came with them, so they shouldn't be hard to find.

My 1 ton didn't come with them either, so I'm taking them off my 3/4 ton that I'm selling and transplanting them. Only 12 bolts to remove the brackets, and I've already moved the springs themselves.

 

Where are you seeing that? I looked on oemdodgeparts.com under 1992 and 1993 Dodge D/W250 and 350, rear suspension, leaf spring, and I don't see anything listed that says "aux" or for that price? All I see listed are the regular leaf springs, not the overload springs. Am I looking under the wrong category?

 

Whoops, find it by doing the search a different way....thanks!
