Description

The ZDS9821 is a new rear driveshaft assembly from USA Standard Gear, designed to replace the original equipment on specific Ford Bronco II models. This conversion shaft features a universal joint design with a 4-bolt flange, replacing the original CV heads to enhance durability and performance. Constructed from high-grade steel, this driveshaft is built new and fully assembled for a simple, out-of-the-box replacement. It boasts a compressed length of 32-11/16 inches, measured from the center of the universal joint to the center of the flange. The driveshaft is equipped with a 1310 universal joint at the differential end and includes new universal joints, slip yokes, and shafts, all lubricated with high-temperature grease for extended service life. Slip yokes and U-joints are also included for a complete installation. To ensure a smooth and vibration-free driving experience, all Zumbrota Drivetrain driveshafts are dynamically balanced at over 3,000 RPM.
