This page distinguishes source-backed fields, unresolved conflicts and unverified legacy records for the 2004 Chevrolet Corvette. Match the exact hardware and manual conditions before maintenance. A source for one field does not verify the other specifications.

These specifications also apply to the 2003 model years — identical specs on file for each year.

GM passenger cars, crossovers and trucks use different wheel hardware families, including seat-style differences that matter when buying aftermarket lugs. Match the listed row and the original seat type; do not infer a truck value from a car, or the reverse.

Frequently asked questions

What is the lug nut torque on a 2004 Chevrolet Corvette?

Specification not verified for this lug nut summary. Do not substitute another model year's value.

What socket size do I need for the 2004 Chevrolet Corvette lug nuts?

Confirm the socket against the actual lug nut; no size is assumed here.

Are the 2004 Chevrolet Corvette 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.
