LC Fab came through again with a clean and easy way to mount an ultra-compact Antigravity 12 cell battery box into the stock location on your 1986-1993 Sportster! These batteries are much lighter and smaller than the stock battery so using this bracket and the LC Fabrications 12 Cell Antigravity Battery Box (see related products below) ypu can mount the battery into the stock location with no welding or fabrication involved on your end!
