The RZR differential swap is one sure way to beef up your Sportsman XP. This option comes with a brand new differential and the steering stem modification plate. This makes your steering stem bearing no longer needed in the differential. The plate bolts right up to the bearing housing, by a bolt on both sides of the stem bearing housing.
 
Dont forget to add on our heavy duty sportsman xp tie-rod and heim kit. To finish your install and properly have the clearance that the larger differentials need. The heavy duty tie-rods are NOT needed if you have one of the lift kits that include tie-rods, or if you have already purchased our heavy duty tie-rods for your machine.
