The Ford F9-3 50 Center 3rd Member 31 Spline Posi 350 is an essential component of your Ford's drivetrain system. This third member is a critical part of the rear differential assembly, which is responsible for transmitting power from the transmission to the wheels.

This feature is particularly beneficial in slippery conditions or when towing heavy loads.

The third member is designed to accommodate a 31-spline input shaft and a 350 cubic-inch engine, making it a popular choice for Ford F-Series trucks with large engines. It's made from high-strength materials, such as cast iron and hardened steel, to withstand the rigors of off-road driving, towing, and daily use.
