2026 Chevrolet Silverado 3500 Hd Srw Lug Nut Torque & Bolt Specs

The 2026 Chevrolet Silverado 3500 Hd Srw lug nut torque is 140 ft-lbs (190 Nm), 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: 140 ft-lbs (190 Nm) · Socket size: 15mm · Thread: M12 x 1.75.

This page is the OEM-referenced fastener summary for the 2026 Chevrolet Silverado 3500 Hd Srw. 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.

Common fastener categories on the 2026 Chevrolet Silverado 3500 Hd Srw

Repair guidance for this model year

For 2026 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.
