PEM Racing Quick-Change Rear End Yokes
PEM Racing quick-change rear-end yokes are forged from steel for strength. The 10-spline replacements are ideal for Winters, DMI, and Tiger quick-changes. They use 1 1/16 in. x 3 7/32 in. 1310 U-joints and standard 1310 U-bolts (not straps). These bolt-on pinion yokes are a crucial component in a vehicle's drivetrain, connecting the differential pinion gear to the driveshaft. They facilitate the transfer of torque and rotational movement, allowing the power from the transmission to be transmitted to the wheels. The pinion yoke is a part of the differential assembly and is essential for enabling the vehicle to turn smoothly.

PEM Racing Ford 9 in. Grand National Rear-End Assemblies
PEM Racing's Ford 9 in. Grand National rear-end assemblies are used for their strength and durability, particularly in racing applications like circle track racing and high-performance street cars. Chosen for their ability to handle high horsepower and extreme cornering forces, the 9-inch design features a full-floating axle, meaning axles are not attached to the housing and instead carry the load independently, offering enhanced safety and reliability compared to traditional axles. The removable center section of the 9-inch rear-end allows for easy gear ratio changes, making it a convenient choice for racers who need to experiment with different gear combinations.
