2009 GMC Sierra 2500hd Lug Nut Torque & Bolt Specs
The 2009 GMC Sierra 2500hd lug nut torque is 140 ft-lbs (190 Nm), tightened with a 22mm 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 · Thread: M14x1.5.
This page is the OEM-referenced fastener summary for the 2009 GMC Sierra 2500hd. 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.
Common fastener categories on the 2009 GMC Sierra 2500hd
- Wheel / lug nut torque and thread spec (covered above)
- Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)
- Engine oil drain plug torque — rarely above 30 ft-lbs; always use a new crush washer
- Transmission pan, valve cover, and intake manifold bolts (low torque, often 89-106 in-lbs)
- Suspension control arm, sway bar, tie rod end and ball joint torque
- Spark plug torque (typically 10-15 ft-lbs on aluminum heads — do not exceed)
- Differential cover bolts (RWD/4WD only) and transfer case fasteners
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 GMC Sierra 2500hd?
The OEM-specified lug-nut torque for the 2009 GMC Sierra 2500hd is 140 ft-lbs (190 Nm), using a 22mm 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 GMC Sierra 2500hd lug nuts?
The 2009 GMC Sierra 2500hd uses a 22mm 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 GMC Sierra 2500hd 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.
