Hello All,

I have 14" rally wheels with 1970 Dart Kelsey Hayes disc brakes on the front and the stock drum brakes on the rear.

Still have the left-hand threads on the driver side.

What are the lug nut torque values in ft pounds?

Thanks in advance.

Stock is the small (4") bolt pattern with a 14" wheel. The 1967 FSM for Dart-Charger- Coronet, Chapter 22, lists 55 lb/ft for 14 wheel stud nut. This includes factory equiped K-H Disks.

My car came from the factory with K-H disks, and I changed my driver's side lugs to right-hand, to prevent tire jockeys from breaking the left hand studs off. Several of the studs had been changed to rt hand on the driver's side before I purchased the car. Mix and match. Yep then it happened to me, some dumb ass put the old monster impact wrench to it and snapped another one off.

Personally, I would run them up to at least 70 ft-lbs, although I am not disputing Bill's factory spec listed at all.

One could bank on those studs being over torqued every time a tire & rim was removed and reinstalled over the years. I know using a four-way bar wrench it is easy to crank the daylights out of a lug nut. The problem with over torquing is it stretches the stud/bolt which weakens it. Torque specs are determined by bolt size, thread count, and the grade of the fastener. Tightening to a slightly higher torque as suggested above probably won't be a problem. The important thing is to make sure all five nuts are torqued to the same value.
