From our own racing and talking with our customers, we have found that too many racers are using their impact to tighten lug nuts with out ever checking with a torque wrench. newer battery powered impacts have the ability to apply over 400 ft lbs. of torque to your lug nuts/studs. Long term this leads to broken lug studs, stripped lug nuts, and ultimately a wrecked race car.
With our new Torque Wrench Kit you will receive a 1/2" Drive Torque Wrench and our K7001-12 Lug Nut Socket. We have spent time doing our own testing and like this combination for its affordability and ease of use.
85 ft lbs. is the recommended torque spec for most circle track wheels.
Check with said manufacture for your specific torque spec.
**This socket is NOT designed for high speed impact use**
