My stock front OEM leaf strings have a negative curvature (center is slightly higher then the ends) like a bell curve. Should they be this way? I just swapped out a set of stiff rancho leafs and do not remember how the OEM units looked.
No one makes an OEM replacement spring at stock height. OME does make a smaller 1.5" lift front spring. Be careful though, they make different front springs and the usual one shops know about is the 2" lift spring.
You could take an Add A Leaf and beef up your current front spring pack with it. We carry an Add A Leaf in stock that will revitalize your stock springs, it will also give about 1" of lift on an SPOA vehicle.
Stock... There shouldn't be too bad of an invert curve. THe samurai comes almost flat from the factory, so a small amount of inverted curve is acceptable, the old full size chevy's came with Invertedly sprung leafs right off the factory floor.
a work of caution with add a leafs.. don't add to many, and too use too thick of a leaf.. Acouple of thin leafs are can be better than one big thick leaf, that will not flex or give to the road's conditions..
Keep it in mind....
