I was looking on ebay for lowering shackles and found springtech 2-3 inch lowering shackles. I know about ground force, and that was what I was initially looking for, but ran across these. Have any of you heard anything about springtech? I searched and only found one post about them. Is 3" too much to drop the rear? Thanke guys in advance.

 

Lots of folks who didn't use Ground Force posted about clearance/interference from the sheet metal seams on the bottom of the bed. Some of them bent/beat/cut the metal out of the way. Personally, I went with Ground Force and haven't had any problems.
