1994 Dodge Ram 3500 Lug Nut Torque & Bolt Specs

The 1994 Dodge Ram 3500 lug nut torque is 100 ft-lbs (135 Nm), tightened with a 22mm 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: 22mm · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 1994 Dodge Ram 3500. 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

Heads up for 1994 Dodge Ram 3500 owners: Vehicles this age frequently have seized fasteners due to thread corrosion. Apply penetrating oil (PB Blaster, Kroil) 24 hours before any wrenching, and have a thread chaser on hand. Lug studs are particularly prone to thread damage at this age; if a nut spins on without engaging, the stud is stretched and must be replaced before the wheel goes back on.

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
