Locking Gas Cap For Chevy Toyota Subaru 7730047020

Secure your vehicle's fuel system with this locking gas cap designed to stop unauthorized access and restore factory-tight sealing performance.

This unit fixes that problem while adding a physical lock to keep strangers from draining your tank. Crafted to match OEM numbers 77300-47020, 10504, and 31780, it attaches directly to your filler neck with zero modifications required.

You will find compatibility across thousands of variations for Chevrolet, Toyota, Nissan, and Honda models spanning 1997 to 2017. Whether you drive a Silverado, Highlander, Altima, or Civic, you get a dependable replacement that resists road debris and harsh weather without losing security ratings.
