2015 Chevrolet Silverado 1500 Lug Nut Torque & Bolt Specs

The 2015 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 2015 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.

Third generation (K2XX, 2014–2018)

The 2015 Silverado 1500 rides on GM's K2XX platform (2014–2018), powered by the 5.3-liter EcoTec3 V8 (355 hp) with an available 420-hp 6.2-liter V8 on upper trims. Both use Active Fuel Management, deactivating four cylinders under light load to save fuel.

Wheels use a six-lug pattern on M14x1.5 studs. The EcoTec3 V8s are aluminum-block engines, so most cover, manifold, and accessory fasteners thread into soft alloy and depend on accurate clamp load rather than force.

Common fastener categories on the 2015 Chevrolet Silverado 1500

Repair guidance for this model year

For 2015 model-year work: This era introduced widespread torque-to-yield (TTY) bolts on head, main, and crank pulley fasteners. TTY bolts stretch permanently when torqued and must not be reused — the spec calls for a fresh bolt every time. Always verify TTY status against the FSM before reassembly.

Frequently asked questions

What is the lug nut torque on a 2015 Chevrolet Silverado 1500?

The OEM-specified lug-nut torque for the 2015 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 2015 Chevrolet Silverado 1500 lug nuts?

The 2015 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 2015 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.
