2015 Chevrolet Corvette Bolt Sizes & Torque Specs

Free OEM-referenced torque and bolt specs for the 2015 Chevrolet Corvette.

This page is the OEM-referenced fastener summary for the 2015 Chevrolet Corvette. 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.

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)

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.

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
