2009 Dodge Ram 2500 Lug Nut Torque & Bolt Specs

The 2009 Dodge Ram 2500 lug nut torque is 100 ft-lbs (135 Nm), tightened with a 24mm socket on M12x1.5 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: 100 ft-lbs (135 Nm) · Socket size: 24mm · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 2009 Dodge Ram 2500. 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.

Stellantis (Jeep/Ram/Dodge/Chrysler) torque values: Wrangler/Cherokee lug nuts spec 100 ft-lbs (135 Nm), Ram 1500 specs 135 ft-lbs (183 Nm), Ram 2500/3500 specs 160 ft-lbs (217 Nm). Most use a 19mm or 22mm socket with M14x1.5 thread on trucks. The Wrangler's hub-centric ring is critical — do not run hub-piloted wheels without it.

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 Dodge Ram 2500?

The OEM-specified lug-nut torque for the 2009 Dodge Ram 2500 is 100 ft-lbs (135 Nm), using a 24mm socket on M12x1.5 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 Dodge Ram 2500 lug nuts?
