Aftermarket Differential Parts

The differential is a relatively durable part in the drivetrain, but it has to withstand a lot of torque and stress. The internal parts are easy to wear. Once the differential fails, it usually makes strange noises (such as whines, clicks), which are obvious fault signals. Whether it's a worn bearing or a broken gear, as long as something goes wrong with the differential, it will affect the machine's ability to transmit power.

Your Differential Parts

FridayParts offers a wide selection of differential parts, suitable for repair from minor maintenance to full overhauls. Understanding each component helps you choose the right one

• Ring and Pinion Gears: The core gear set that transfers power from the driveshaft and multiplies torque to the wheels.
• Spider and Side Gears: These smaller gears are located inside the carrier and allow your wheels to rotate at different speeds when turning.
• Differential Carrier: The housing that contains the spider and side gears, and to which the ring gear is bolted.
• Complete Differential Assembly: A pre-assembled unit including the carrier, gears, and often bearings, ready for a direct drop-in installation.
• Lockers and Mini Spools: Performance parts designed to lock the axles together, providing maximum traction by forcing both wheels to turn at the same speed.
• Differential Covers and Housings: Protective casings that enclose the internal components and hold the gear oil. An upgraded cover can improve cooling and strength.
