Let's see your Dodge pickups

I bought my 3500 single new. It always sagged a little with a loaded to the max enclosed race car trailer with everything we traveled across country to race.
I bought a Dual wheel same truck 3500 the springs had 3 leafs verses the 4 in leafs the single but they were thicker. I tow a 36 ft equipment trailer with that truck so we upgraded it to class 10 as per the dealer 5500 springs were installed. The truck took some pocket mods to the frame saddles.

Having the dual wheel springs left over we installed them in the single wheel. What a difference I should have done this when I bought it. I thought buying a 3500 you would get the same springs as a duall wheel 3500 you don't.

I would recomend anyone with a 2500 to install 3500 dual wheel springs. It totally change the truck It never gets close tho the factory helper springs with the trailer. And no bouncing on those highways with dips in the road.

This was the best thing I ever did to that truck. The dual wheel on the other hand rides like a brick empty. We put a 4 x 8 x 3/8's steel plate in the bed so it is bearable when driving empty with the 5500 springs.
