Installation notes
Fitted exclusively on the left side of the vehicle. Note: left-hand thread turns clockwise to loosen. Tightening torque per TM: 60-75 ft-lbs. Always verify that wheel studs also have left-hand thread before fitting.
Compatibility
Fits vehicles with 1/2"-20 wheel studs. Not compatible with Budd wheels which require a larger nut (1½" hex). GMC CCKW and Dodge WC have different sizes - check your specifications.
Historical context
Left-hand thread on the left wheel side was a safety measure: during forward wheel rotation, the nuts would tighten rather than loosen. This system was applied to many WWII American military vehicles and some early civilian Jeeps.
