Polaris RZR XP 1000 900, Polaris Ranger 800 – 11-16 RZR and Ranger Front HD Diff
Internally, the 1333104 and 1333105 OEM drives each have 10 rolls per side, held within the pockets of the roll cage. It is the rolls that transfer the torque (via a wedging action against the ramps within the ring gear housing) to each of the front drive shafts. The 1333285, by contrast, has 12 pockets per side. More pockets or rolls result in a higher torque capacity. Our HD16 drives are a 12 pocket version with a 7075 aluminum cage. So a customer replacing a -104 or -105 drive with our HD16 will be upgrading to a much stronger design. The OEM 1333285 already has 12 pockets, but of course not the aluminum cage, so once again our HD16 is superior to OEM.
