No,,I am real happy with the downey products..I have never had a problem with any thing from them..I used to have all owney spring on my runner before now..I am not real impressed with the checy springs and I want somthing different..I really like the flex the taco springs give..They use more then a 2 spring pack stock.I would have to look because I don't remember off hand,,,I might have to have a spring shop make up some close to the toco springs..we;ll see..
