Our take on the Tammesy Rear Differential Assembly for Polaris Scrambler Sportsman XP 1000/850

The Tammesy Rear Differential Assembly is a complete drop-in replacement rear differential for Polaris Scrambler and Sportsman XP 1000 and 850 ATVs. It ships as one unit with the differential housing and internal gears already assembled, so no separate parts are needed for installation. The cast iron and aluminum housing is built for bearing load and wear resistance under trail and utility use. It suits riders replacing a failed or noisy factory rear diff on these Polaris models; compared with OEM parts it is a lower-cost aftermarket option, and buyers should confirm the exact model and year fit before ordering.

Questions and answers

Will it fit my Sportsman XP 1000?
It is listed for Polaris Scrambler and Sportsman XP 1000 and 850 models. Confirm your exact year and submodel before ordering, since Polaris changed rear differentials across generations.
Is it a complete assembly?
Yes. It ships as one rear differential assembly with the unit already built, so no additional differential parts are required for installation.
What is it made of?
The housing combines cast iron and aluminum. That gives rigidity and bearing support at the gear area while keeping weight down compared with an all-iron housing.
Do I need to add gear oil?
Plan on filling it with the fluid Polaris specifies for your model. The listing covers the assembly only, so fluid and any gaskets or hardware beyond the unit are not included.
How does it compare with an OEM Polaris differential?
It is an aftermarket alternative to the factory unit, aimed at the same fit and function at lower cost. OEM parts carry Polaris branding and warranty support; this one trades that for value.
Is it hard to install?
Replacing a rear differential means removing the rear housing, axles and driveshaft connection, so it is a job for someone with ATV drivetrain experience or a shop.
Where is the Tammesy Rear Differential Assembly for Polaris Scrambler Sportsman XP 1000/850 cheapest?
At Amazon, for $202.99, as of our latest check.
