Large black set is 33", heavy duty 7 Leaf slipper springs, $30 obo, the smaller set is approximately 25" four leaf spring.$20obo,Both have 1-1/2" holes for bolts. I don't know the capacity of them so please don't call with a bunch of stupid questions. North Springfield. Send me a text if you're interested and I'll call you back. I don't accept phone calls because I get 20 spam calls a day. Thanks have a good day
