the biggest issue i have now is the warranty period ....even if the dormans are not heavy duty if they sag i can just get new ones via warranty.....and even though the crowns are heavy duty they can sag after a year and i would be **** out of luck lol....

hi.....thanks for the info and to me they arent just leaf springs....i want something that will last 5-10 years not 1 year.....and i do carry 200-300 lbs of tools in jeep at all times....and since dorman does not list any technical specs on their springs its hard to compare what im buying.....the crown hd have a 750 load rating and 7 inch arc which is 1.5 inches more than dorman...and the dorman 929-301 load rating is unknown.....i dont want to buy leaf springs and have them sag a year later....the dormans have lifetime warranty and the crowns only have 1 year warranty...the 1 yr warranty scares me but i do want a heavy duty spring

some people are saying the dorman 929-301 are actually considered heavy duty..is this just made up BS or true backed up by facts? a 5 1/2 arc is on the low end ...heavy duty would be 6-7 inch arc
