Yes QA1's are great i don't know if you saw my thread but i am using QA1's and there great but i don't care what any one says and i always throw my weight in the mix but dont get the 350's go with the 400# springs,it will handle better and not bottom out,Beebani makes brackets which you can make yourself but they are worth it to me,like i said it rides better way better but i bottom out so 350's to 400's and i'm good.And i have plans for the 350# springs already.hint hint.
