5/8" Mil-Spec Universal Joint

These Universal Joints are similar to military specification joints for aircraft and have become the select choice of drag racers due to their lightweight design. A lubricant filled silicone boot provides maintenance-free operation for extended universal joint life. This boot is designed for high temperature environments with a continuous rating of 650°F. Please note, nominal size is outside diameter.

IMPORTANT: This is a lightweight application that is not designed for circle track, street, or highway use and is not recommended for steering.
