The Rear Differential Assembly for Polaris 1332914 1332802 is a high-quality component that is designed to replace the original parts in your Polaris vehicle. This assembly has a differential gear ratio of 10:37 and features spline counts of 22 and 28 on the input couplers and shaft, respectively. It uses SAE80 Hyphoid Gear Oil for lubrication, and additional lubrication is not required. It is important to check the lubricant level before operating your vehicle.
The differential assembly is an essential component in a vehicle's drivetrain, responsible for transmitting power from the engine to the wheels. The differential gear ratio determines the amount of torque that is supplied to the wheels, and the input couplers and shaft transmit this torque to the wheels. The differential assembly helps to optimize traction and reduce wheel wear, ensuring your vehicle operates smoothly and safely.
The differential assembly works by taking the power from the engine and transmitting it to the wheels. When a vehicle turns, the wheels on the outside of the turn must rotate faster than those on the inside. The differential assembly allows for this by using a system of gears that allows the wheels to rotate at different speeds while still receiving power from the engine. The differential gear ratio determines the speed at which the wheels rotate relative to each other.
The rear differential assembly is commonly used in off-road vehicles, such as ATVs and UTVs. It is also found in some passenger cars and trucks, particularly those with four-wheel drive or all-wheel drive systems. The Polaris rear differential assembly is compatible with a wide range of Polaris vehicles, as listed above.

The main components of a differential assembly include the ring gear, pinion gear, carrier, bearings, and seals. The ring gear is attached to the differential case, while the pinion gear is attached to the driveshaft. The carrier holds the ring and pinion gears and is attached to the differential case. Bearings support the rotating components and reduce friction, while seals prevent leaks and contamination.
To ensure the differential assembly operates correctly, it is important to check the lubricant level regularly and change the oil as recommended by the manufacturer. In addition, the assembly should be inspected for wear and damage periodically, and any worn or damaged components should be replaced. Proper maintenance will help to ensure the assembly operates smoothly and reliably for years to come.
In recent years, advancements in differential technology have focused on improving fuel efficiency and reducing emissions. Some manufacturers have incorporated electronic control systems that can adjust the differential gear ratio based on driving conditions, while others have developed hybrid and electric drive systems that use different types of differentials to optimize power delivery.
