The Dorman 578-183 fuel tank strap is a direct-fit steel replacement designed to secure the fuel tank on compatible Chevrolet and GMC trucks with OEM-equivalent form and function.

If you're replacing or servicing a fuel tank, the tank straps are critical components that hold the tank firmly to the vehicle frame. Dorman engineered this strap to match the original equipment fit and performance, using durable materials meant to resist road and weather exposure. Before ordering, verify fitment for your exact model and trim with the vehicle garage tool to ensure correct compatibility.

How does this strap match original equipment specifications?

The 578-183 is manufactured to mirror the geometry and mounting points of the factory strap so it installs and functions like the original.

The material and dimensions are engineered to meet the load and clearance requirements typical for the listed Chevy and GMC pickups.

Will this strap resist corrosion and road wear?

Replacement is recommended during fuel tank removal or when fasteners and straps show wear. Installation typically requires basic hand tools and safe vehicle support; torque and hardware should match OEM specifications.
