thanks joey! i have the BDS 6 inch lift. Its a bit pricey but its well worth the money,
however i snapped both rear springs and had to have them replaced ( witch is free as long as you are the original owner of the lift, BDS will send you a brand new part no questions asked if your broke)
but for what i put them threw im very very impressed.
also BDS will replaced them after a year or two if they start to sag, ( ive owned mine for a while and they have not even began to sag)
