What is the torque spec for the Chevy SS lug nuts?
The lug nuts on the Chevy SS should be tightened to 140 Nm (about 103 ft-lbs).
The 2014–2017 Chevy SS relies on five-lug wheels with conical-seat lug nuts. Getting the torque right is essential for proper wheel retention and even loading of the wheel studs. This article outlines the official spec, how to apply it correctly, and practical considerations for aftermarket wheels or non-standard setups.
Official torque specification
To apply the factory guidance accurately, refer to the torque value and the recommended tightening sequence for the stock wheels. The following details summarize what GM documentation commonly lists for the Chevy SS.
- Torque specification: 140 Nm (103 ft-lbs) for lug nuts on stock Chevy SS wheels with conical-seat lug nuts.
- Tightening sequence: Tighten in a star or cross pattern to ensure even clamping. For a 5-lug setup, a typical sequence is 1-3-5-2-4, then recheck in the same pattern to reach final torque.
- Seat type and compatibility: Use lug nuts that match the wheel’s conical seat and thread pitch. If you install aftermarket wheels with a different seat type or thread specification, follow the wheel manufacturer’s torque spec.
Following the official spec and proper sequence helps minimize rotor and stud stress and reduces the risk of wheel loosening. After installation, use a calibrated torque wrench to confirm every lug nut is at the specified value, and recheck after an initial road test if possible.
Practical guide to applying the torque
Before listing the steps, here is a practical overview of how to apply the torque correctly and safely.
- Ensure the wheel is properly seated on the hub and that the lug nuts are clean and free of debris before torquing.
- Hand-tighten all lug nuts first to seat the wheel, then use a torque wrench to apply the final torque in the recommended sequence to the specified 140 Nm (103 ft-lbs).
- Avoid using impact tools for final torque; use a torque wrench to prevent over- or under-tightening.
These steps help ensure even loading, proper wheel retention, and safer driving dynamics. If you switch to aftermarket wheels, always verify the wheel manufacturer’s torque spec and seat requirements, and adjust accordingly.
Common caveats and additional notes
While the factory spec is 140 Nm (103 ft-lbs) for Chevy SS stock wheels, some aftermarket wheels, lug nuts, or wheel hubs may require different values. Always verify any non-OEM components against their documentation and, when in doubt, consult a qualified technician or GM service manual for your exact vehicle configuration.
Summary
For the Chevy SS with stock five-lug wheels, tighten lug nuts to 140 Nm (103 ft-lbs) in a star/cross sequence (for example, 1-3-5-2-4) and recheck after installation and road testing. Use lug nuts that match the wheel’s conical seat and follow the wheel manufacturer’s guidelines if aftermarket parts are used. Proper torque helps ensure wheel security and longevity of the fasteners.
What is the torque spec for Chevy lug nuts?
Chevy lug nut torque specs vary by model and year, but common values are 140 lb-ft for many 1500 and HD models, with some newer models ranging up to 150 lb-ft. For heavy-duty trucks, it can be 165 lb-ft for dual rear wheels. The most accurate torque specification for your specific Chevy can be found in the vehicle's owner's manual, often in the spare tire or emergency procedures section.
Examples of Chevy lug nut torque specs
- Silverado 1500 (2007-2018): 140 lb-ft
- Silverado 1500 (2019-2021): 140-150 lb-ft (depending on model)
- Silverado 2500HD/3500HD (2011-2021): 140 lb-ft (single rear wheel)
- Suburban (1500): 140-190 Nm (approx. 103.5–140 ft-lb)
How to find the correct torque spec
- Check the owner's manual: The owner's manual is the most reliable source for your specific vehicle. Look for a section on emergency procedures or the spare tire.
- Look for a sticker: Some vehicles have a sticker on the driver's side doorjamb with maintenance information, including wheel torque.

Specifications. Torque: 420 lb-ft.
Is 1/2 or 3/8 better for lug nuts?
Is 1/2 or 3/8 better for lug nuts? A 1/2-inch drive is better for lug nuts because it covers the torque range most vehicles require and allows you to tighten them with confidence.
