2020 Chevrolet Silverado 1500 Lug Nut Torque & Bolt Specs

The 2020 Chevrolet Silverado 1500 lug nut torque is TTY: 15+60°, tightened with a 15mm socket on M12 x 1.75 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: TTY: 15+60° · Socket size: 15mm · Thread: M12 x 1.75.

This page is the OEM-referenced fastener summary for the 2020 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.

Fourth generation (T1XX, 2019–present)

The 2020 Silverado 1500 is built on GM's T1XX platform (2019–present), with a 355-hp 5.3-liter and an available 420-hp 6.2-liter EcoTec3 V8. These engines use Dynamic Fuel Management, which can run any of 17 cylinder patterns rather than the earlier system's simple eight-or-four switch.

The six-lug, M14x1.5 wheel-stud convention carries over from the K2XX generation. As before, the aluminum V8 blocks mean fasteners threading into soft alloy should be set with a calibrated wrench.

Common fastener categories on the 2020 Chevrolet Silverado 1500

Repair guidance for this model year

For 2020 late-model work: Modern vehicles increasingly use aluminum body and suspension components. Aluminum fastener torque is typically 60-70% of equivalent steel torque, and aluminum threads strip easily. Use a calibrated torque wrench and apply anti-seize on any steel fastener threading into aluminum.

Frequently asked questions

What is the lug nut torque on a 2020 Chevrolet Silverado 1500?

The OEM-specified lug-nut torque for the 2020 Chevrolet Silverado 1500 is TTY: 15+60°, using a 15mm socket on M12 x 1.75 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 2020 Chevrolet Silverado 1500 lug nuts?

The 2020 Chevrolet Silverado 1500 uses a 15mm 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 2020 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.
