2011 gmc denali body mount bolts

[p_etterman]

What is the proper torque specs on the body mount bolts on the 2011 denali hd . I installed some running boards on it and one dealer told me 54 ft/lbs and the other told me 122 ft/lbs. Quite a difference. Someone should know how tight the 6 body mount bolts on a crew cab should be.....shouldn't they?

So the 6 - 10.8 body to frame bolts should be at 74lb ft correct?

You got it, 74lb ft. The dealer was just off by 20lb ft. Good luck and keep us posted and would not hurt for you to use lock tight then spray them with paint to keep corrosion to a minimum.
