So heres a 1: Cheap, 2: better riding, 3: stronger spring that you can get off any 3/4 ton 1968-1971 dodge truck. These were off a 1970 camper special D200 and have a military wrap on one end. The early truck springs were reversed end to end. I ended up taking the pair and measured them to mine. They measured exactly the same to cummins springs and had 1.75" of more arch. They were also 7 leaf rather than 6 and had two non sprung leafs on the centering bolt which I ended up taking off so I could use my existing u bolts. This spring was switched end to end and the military wrap is on the (now front) eye and clears the front spring bracket by 3/16 of an inch! These springs fit like a glove in this truck and with the leafs lubricated with never-seeze and new bushings and shot shocks it rides better than my new stock cummins springs which were already arching a little the other way....
PICS!!!
Stock cummins vs 1970 springs
Height difference:
Notice here the springs have just a little positive arch. They settled a lot more than I thought coming off the jack but shouldn't any more as they have been under a truck for 32 years now and are well broken in. The amount the spring settles when let off the jack stands is quite a bit more and probably contributes to the smoother ride as well....
You could use these and a 1" non sprung leaf and achieve a 2" lift and you would have a better ride, longer lasting leaf (because of the military wrap) and cheaper than any lift spring out there even after the boneyard price, rebuild price and new bushings you would still be less than half of lift springs and give the truck a little better stance. I plan to do a Jungle shackle flip on the back and eliminate blocks next! AC may come first tho!
