Our Military Specification (Mill-Spec) U-joints are made to military specifications for aircraft. These U-joints have become a favorite among racers for their lightweight design and low maintenance.

The silicone boot is lubricant-filled which requires no maintenance. This design gives the U-joint a much longer life. The silicone boot is also designed for the high temperatures caused by racing with a continuous 650 degrees F rating.
