What Grigg said. Eaton Detriot but a caveat, If you ask for lowered springs they just cut stock springs then if you decide you want them lower and cut them again you will get a harsh ride again. My bad experience. I don't blame them I did not do, due diligence. The second time they told me they would not be returnable because they had been cut. I had thought they custom made them. BTW mine was an AMC Pacer IFS.
