I recently purchase a spacer/AAL lift kit from a fellow TW member and decided to use blocks on the rear instead. They are used but look brand new. I was told they were on the truck for about a year. They are Fabtech AAL that will lift the rear about 1.5” and will include the U bolt if you want but they are just the stock U bolts the seller gave me and said they will work. They are not TSB. Email or PM me. See pics. $45 + $15 S&H.
