SuperATV Polaris RZR 800 Rear Differential vs East Lake Axle Polaris RZR 800 Rear CV Axle Kit

These are not competing parts. The SuperATV unit is a billet rear differential upgrade for 2021+ RZR Trail S 900 Sport machines. The East Lake Axle kit is a pair of rear CV axles plus differential seals for 2009–2014 RZR 800 S and RZR 4 60-inch models. Buy the SuperATV if you have a newer Trail S and want a stronger diff case and sprague carrier for hard lock engagements. Buy the East Lake kit if you have an older 800 S or 4 and need to replace worn axles and leaking seals. Owners rate the SuperATV for build strength; the East Lake kit is a maintenance part with a two-year warranty.

• Choose the SuperATV Rear Differential if you own a 2021+ RZR Trail S 900 Sport and want a stronger-than-stock diff for hard lock engagements.
• Choose the East Lake Axle kit if you own a 2009–2014 RZR 800 S or RZR 4 60-inch and need new rear CV axles and differential seals.
