Are Aftermarket Parts Covered by Auto Insurance? (US)

Only if declared. Modifications typically capped at $1K–$5K without a custom equipment endorsement. Performance mods may void coverage.

The short answer

Standard auto policies exclude or sub-limit custom parts to $1,000–$5,000. Add a Custom Parts and Equipment (CPE) endorsement listing each modification with receipts to insure aftermarket wheels, audio, wraps, lift kits, and interior mods. Performance modifications (turbos, ECU tunes) may void collision coverage entirely at some carriers — disclose or expect denial.

Frequently asked

Do I need appraisals?
For anything over $2K, insurers usually require receipts and photos. High-end builds may need a professional appraisal.
