This is a new Motive Gear G895456IFS Ring & Pinion Gear Set for GM 9.25 R/P 4.56 IFS and for the AAM 11.5" 14 bolt rear end. It includes a ring gear and a pinion gear, still in original packaging, though the outer box shows some wear. Bought for a 2004 Duramax but ended up putting in other gears by the time these arrived. Brand new, never installed.
