2021 RAM Promaster Torque
Wheel Lug Nut Torque Specification
Lug Nut Torque
145
ft-lbs
The 2021 RAM Promaster lug nut torque specification is 145 ft-lbs. This is the manufacturer-recommended torque value for all wheel lug nuts on the RAM Promaster.
Always use a calibrated click-type torque wrench and tighten lug nuts in a star (criss-cross) pattern. After mounting new wheels, tires, or rotors, re-torque after 50–100 miles of driving to account for settling. Over-torquing causes warped brake rotors and stretched studs; under-torquing risks wheel separation.
