Recommended Torque for Tightening Curt Hitch Balls to Ball Mount
Updated 12/11/2025 | Published 03/10/2015
Question:
What is the recommended torque when mounting to ball mount
asked by: John J
Expert Reply:
Curt recommends the use of 250 ft/lbs of torque when tightening the nuts of their hitch balls with a 1 inch diameter shank like the part # C40034 that you referenced.
The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank tighten to 250 ft/lbs, and for a 1-1/4 inch shank 450 ft/lbs.
