What is the lug nut torque for a GMC?

It depends on the model: GMC Sierra — 140 ft·lbs (190 N·m); GMC Acadia — 100 ft·lbs (136 N·m); GMC Terrain — 100 ft·lbs (136 N·m); GMC Yukon — 140 ft·lbs (190 N·m).

What size socket do GMC lug nuts need?

GMC models on this page use 19 mm, 22 mm. Always use a six-point socket; a twelve-point rounds the flats.

Do all GMC models use the same bolt pattern?

No. GMC models on this page use 5×114.3, 5×120, 6×139.7. Bolt pattern must match exactly for a wheel to fit.

How GMC Wheel Torque Works

GMC shares GM hardware with Chevrolet: full-size Sierra and Yukon take 140 ft·lbs on 6-lug M14×1.5 studs (22 mm socket), while the Acadia and Terrain crossovers take 100 ft·lbs (19 mm socket).

Tightening Any GMC Wheel

Star sequence, always. Never work around the wheel in a circle. Five-lug wheels go 1 → 3 → 5 → 2 → 4; six-lug wheels go 1 → 4 → 2 → 5 → 3 → 6; eight-lug wheels go 1 → 5 → 3 → 7 → 2 → 6 → 4 → 8.

Two passes. Snug everything to about half spec first, then bring each lug nut to full torque in the same order.

Dry threads. GMC publishes these figures for clean, dry threads. Lubricant at the same wrench setting produces far more clamp load than intended.

Re-torque after 50–100 miles. This matters most on alloy wheels and after any wheel-off service.

These are reference values for the generations listed on each model page. Trim levels with different wheel packages, and any vehicle fitted with aftermarket wheels, can differ — confirm against your own owner's manual. Full lug nut torque guide →
