Description
Boxing the rear frame rails on a 1947–1953 GMC or Chevy usually starts with cardboard templates and a cutoff wheel. These plates are laser cut to shape, which takes the guesswork and the time out of that part of the job.
Features
- Laser cut, so there is no templating or cutting metal yourself.
- Three interlocking pieces per frame rail let you fine-tune the fit for your particular truck.
- 12 gauge metal gives you enough material to drill and tap for mounting lines and harnesses.
- Sold as a pair, six pieces in total.

Common questions
Do I need to make templates?
No. The plates are laser cut to shape, three interlocking pieces per frame rail so the fit can be fine-tuned to your truck. A pair is six pieces in total.
Can I mount lines and harnesses to them?
Yes. They are 12 gauge, which leaves enough material to drill and tap where you need to mount lines and harnesses.
How do I know it fits my truck?
This part is listed for 1947–1953 Chevy and GMC 3100, 3600 and 3800. 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 Canada Post. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
Can I install this myself?
It is designed for an at-home install. Read the fitment notes and the Installation tab on this page before you start for anything that needs drilling, trimming or welding, and where an installation guide or video exists for the part it is linked there.
