You may purchase this with the differential plate (see picture). These normally sell for $59, but with the purchase of the radius rod kit you may add this for an additional $30. The Alba Racing differrential plate is CNC machined from 5/16" thick billet aluminum. It will not break or bend like the stock one. Note the incredible workmanship on the removable differential oil drain cover. The machining is so perfect you can barely see it. (This is the only differential cover on the market with easy access to the differential drain plug. So you will not have to remove the entire plate to service the oil. The finish is shiny anodized black.
If you are racing your RZR 900 you will want straight radius rods not high clearance.
