Third Member Assembly
A third member assembly, also known as a differential third member, is a critical component in a vehicle's drivetrain system, specifically in rear-wheel drive and four-wheel drive vehicles. It houses the differential, which is responsible for distributing power from the transmission to the rear wheels while allowing them to rotate at different speeds during turns. The third member assembly consists of the differential itself, along with various gears, bearings, and other components necessary for power distribution and smooth operation. It's an essential element that influences a vehicle's traction, stability, and overall performance.

Selecting the correct third member assembly is essential to ensure the optimal performance and functionality of your vehicle. When choosing a third member assembly, you need to consider several factors, including the vehicle's make, model, rear axle type, gear ratio, and intended usage. The 9 inch center section is a popular choice known for its durability and strength, making it suitable for various high-performance applications. Depending on your vehicle's needs, you may also need to select a specific gear ratio to achieve the desired balance between acceleration and top speed.
