- Available in two bead rolled styles or with no bead rolling at all.
- Made to be installed by the do-it-yourselfer.

Choose your style

Common questions
Does the panel arrive finished, or does it need work?
It arrives laser cut and formed in raw steel, ready to be fitted. Plan on final trimming to your own truck, then prep and paint - the parts are shipped bare on purpose so you are not stripping a finish off before you weld.
Can I bolt it in instead of welding?
On most panels, yes. Several carry laser etched markings to drill from if you would rather bolt them, and customers have welded, screwed, riveted and bonded them in. Check the Features list on this page for what this particular panel is set up for.
How much trimming should I expect?
Usually a few minutes with a cut-off wheel. Fifty years of body work, previous repairs and factory tolerance mean no two cabs or beds are identical, so the panels are cut slightly generous rather than short. Test fit before any final welding.
How do I know it fits my truck?
This part is listed for 1955–1959 Chevy and GMC 3100, 3600, 3800 and Suburban. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
How long before it ships?
It is a stock item and leaves our warehouse in 1-3 business days. Transit after that is typically 2-5 business days in the United States. Larger orders can arrive in more than one box on different days.
What if it is not right for the truck?
You have 30 days from delivery to return it by mail. Return shipping is on you, and the part needs to come back uninstalled and unmodified - once a panel has been trimmed or welded it cannot go back. Made-to-order items are final sale. The full terms are on our returns page.

Great Product. Great Quality and Fast Shipping
Great, fit perfectly
Got the deedee style firewall fillers for my 55 and they fit amazing. They look pretty damn sweet and they showed up extremely quick.
LSFab did a great job with these!!!
