Description
The upper cowl filler finishes the engine bay on a 1947–1954 Chevrolet or GMC truck, and it pairs with the rest of our replacement filler panels. The factory piece rusts and takes damage over time, and this one is laser cut to replace it.
On a 1947-54 Chevy or GMC truck, the upper cowl filler is one of the panels that ties the engine bay together. Whether you are bringing back the original look or building a custom engine bay, a new 18 gauge steel panel gives you a clean starting point instead of repairing a rusted or damaged factory piece.
Features
- Laser cut from 18 gauge steel.
- Available blank or bead rolled.
- Made to work alongside our other 1947–1954 filler panels.
Choose your option
- Blank
- Bead rolled
Pick the blank version if you want a smooth panel to finish however you like, or the bead rolled version for a more detailed custom look. Either option is laser cut from the same 18 gauge steel and is made to work alongside our other 1947-54 filler panels, so you can match the cowl to the rest of the engine bay on your 47-54 Chevy or GMC truck.

Bead Rolled Upper Cowl Filler - 47-54 GMC Chevy Truck
Common questions
Does the panel arrive finished, or does it need work?
It ships bare, ready for you to fit and then prep and paint, coat or cover however suits the build.
Can I bolt it in instead of welding?
It depends on the panel. Several go in more than one way - laid over the existing panel, butt welded, screwed, riveted or bonded - and the Features list and installation notes on this page say what this one is set up for.
How much fitting should I expect?
Test fit before anything is welded or drilled. Fifty years of body work, previous repairs and factory tolerance mean no two cabs or beds are identical, so expect some final fitting to your own truck.
How do I know it fits my truck?
This part is listed for 1947–1954 Chevy and GMC 3100, 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 generally ships within 1-3 business days. Carrier transit time is on top of that, and 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 request a return. The part needs to come back new, uninstalled and in its original packaging - once a part has been trimmed or welded it cannot go back. Return shipping is at your cost, and we ask that returns come by USPS. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
