The spring I'm looking at is a 1000lb. cap. spring, 2 mounting plates,u bolts with nyloc nuts ,bushings,and shackles, shipped to Az for 65.00 to 70.00 bucks. I think this is reasonable if it will work. Spring is 26 inch eye to eye, center mount, 4inch unloaded arch. I wounder if I should go to 1500 lb. capacity, or would that be over kill?
