I thought the aam cover was more like $130 but it still well worth 185 for the cooling it does. The aam. cover also has grooves cast on the inside to direct oil out to the carrier bearings. My truck has 120,000 miles and it has always been used for towing by the previous owner and myself and the bearings are in the best shape that I've seen in any of my trucks... I check my diff with a dial indicator every blue change. Craig
About 4 or 5 years ago, you could find them online for less than $100 easily......then one day they just doubled....

FCA at it's best....
