2009 Chevrolet Silverado 1500 Lug Nut Torque & Bolt Specs

The 2009 Chevrolet Silverado 1500 lug nut torque is 140 ft-lbs (190 Nm), tightened with a 22mm (13/16") socket on M14x1.5 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass.

Lug nut torque: 140 ft-lbs (190 Nm) · Socket size: 22mm (13/16") · Thread: M14x1.5.

This page is the OEM-referenced fastener summary for the 2009 Chevrolet Silverado 1500. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

GM lug-nut torque clusters around 140 ft-lbs (190 Nm) for half-ton Silverado/Sierra and 100 ft-lbs for passenger cars like Malibu, Impala, and Cruze. GM heavy-duty trucks (2500HD/3500HD) jump to 165 ft-lbs. Most GM passenger cars use a 19mm socket; trucks moved from 22mm to 22mm-with-deep-well in 2014. Watch for GM's flat-flange lug nut design on the Silverado — the standard cone-seat aftermarket lugs will not seat correctly.

Repair guidance for this model year

For 2009 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly

Frequently asked questions

What is the lug nut torque on a 2009 Chevrolet Silverado 1500?

The OEM-specified lug-nut torque for the 2009 Chevrolet Silverado 1500 is 140 ft-lbs (190 Nm), using a 22mm (13/16") socket on M14x1.5 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 2009 Chevrolet Silverado 1500 lug nuts?

The 2009 Chevrolet Silverado 1500 uses a 22mm (13/16") socket. A 6-point impact-rated socket is recommended over a 12-point chrome socket — 12-points round off lug nuts under impact-driver use.

Are the 2009 Chevrolet Silverado 1500 fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
