Fuse Box, Fuse, Relay

Browse New OEM fuse boxes, individual fuses, and relays for GM vehicles. Our factory-original electrical protection components are sourced from GM surplus — the correct amperage ratings, relay logic, and connector specifications for your vehicle's electrical system.

Electrical protection components are safety-critical — they protect wiring and components from damage in overload and short-circuit conditions. OEM fuse boxes, fuses, and relays are rated and configured to the exact electrical architecture of your vehicle, preventing both nuisance trips and unprotected circuit conditions.

Match all part numbers carefully against your existing components. Contact us with your vehicle's option content for fitment assistance on fuse box and relay configurations.
