2026 Chevrolet Trailblazer Lug Nut Torque & Bolt Specs

The 2026 Chevrolet Trailblazer lug nut torque is 100 ft-lbs (140 Nm) 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. The wheel bolt pattern is 5x115.

Lug nut torque: 100 ft-lbs (140 Nm) · Thread: M12x1.5 · Bolt pattern: 5x115.

This page is the OEM-referenced fastener summary for the 2026 Chevrolet Trailblazer. 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 Trailblazer

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)
Engine oil drain plug torque — rarely above 30 ft-lbs; always use a new crush washer
Transmission pan, valve cover, and intake manifold bolts (low torque, often 89-106 in-lbs)

Differential cover bolts (RWD/4WD only) and transfer case fasteners

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.

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
