HD Type Universal Joints incorporate induction hardened yoke ears for longer life using the standard pin and block design. It is ideal for applications with angles up to 25° and speeds of up to 1,750 RPM. Boot retaining grooves are standard. HD Type are available in round, hex, splined, or keyway bore.

For optimal wear and extended life, lubrication and boots are required. (Boots are available for purchase separately.) HDD and HDDX drive line assemblies can also be provided to increase life of your drive line or drive shaft.
