Allows fitment of 31 tires on Polaris Sportsman ATVs with the use of High Lifter 2 lift kits
Redesigned A-arms have a slightly different geometry (angle from the frame) that moves the axle, bottom of the strut, and wheel hub forward from the stock wheel mounting point
Produces longer wheelbase and additional clearance behind the front tires so tire does not rub the lower inner fender
