    What pound do you torque your lug nuts too on a 1500 4x4?

    Is it any different for aftermarket wheels?

    Chevy says my HD should be at 140 ft./lbs. and my tire guy agrees. I believe that my manual also showed specs for 6 lug 1500's and it was also 140 ft./lbs. these specs are for the factory donut holders.

    Did a quick search b/c all this talk got me wondering.

    For what its worth Superlift Online Instructions for the 1500 says 85 ft. lbs
    http://www.superlift.com/3280IN_2.pdf Page 15 at the bottom I think.
    But this dosnt make it official, just wanted to point it out

    I am 100% positive that OBS trucks require 140 ft/pounds. I am 75% sure that the NBS trucks require the same. It should say in the owners manual.

    In addition, it is not a good idea to overtorque in hopes of lessoning the chance of a lugnut coming off. It will actually increase the chances of failure.

    Thanks guys, the man at 4wp's torqued mine to 100ftlbs...is this okay?

    He said 1/2 tons they torque to 100ftlbs...3/4 tons to 140ftlbs and mini-trucks to about 75ftlbs.

    He didnt reference a manual but he may be experienced enough to know I just wanna make sure this is correct.

    Any more replies are very welcomed and appreciated

    Yep I checked once with Discount Tire, 120 ft./lbs.

    Hey Luke, Maybe that is why you ditched a wheel.

    I would think that the rating would differ based on wether you have steel or alum wheels....... maybe not....

    I don't think they would because alum wheels are built thicker than steel ones, whcih I would think would make up for the strength difference.

    The spec for the 88-98 GM K1500-K3500 trucks with the six bolt wheels is 120 FT LBS. The old style(73-87) trucks had little 7/16 studs and were probably around 85.

    In my 1999 Chevrolet Silverado Owner's Manual

    page 6-74 under Capacities and Specifications

    C/K 1500 6 bolts (14mm) 140 lb-ft (190N-m)

    I usually only set mine to around 130 after I rotate and then after about 50-100 miles I check them all again with a torque wrench and then I call it good till the next time I rotate.

    At Discount Tire we have to torque the wheels to 140 ft.lbs. We do both NBS and OBS at the same.

    Torque specs for lug nuts has little to do with the number of studs your wheel uses. It is based on the diameter of the stud. There are SAE torque specs for each size, and the manufacturers recommendation will usually be pretty close to that.

    The reason you are seeing different specs for different trucks is that heavier duty trucks generally have larger diameter studs. Wheel torque on a 1 ton will be higher than a 1/2 ton.
