Upgrading Older Retrax Cover Rails with T-Slot Rails for Tonneau Cover

Updated 08/04/2025 | Published 07/26/2025

Question:

Want to replace older retrax cover sides with a t slot option. I don’t know the model of the retractable cover but the serial number is 19110331377007 and the side bars that connect to the truck is 82831. Is this possible?

Hey Andrew, thanks for giving all of the information!

I reached out to my contact at Retrax and they asked what the year/make/model is, how big of a bed you have on your truck, and if you have any sort of special in-bed application like a utilitrack. I'm not sure why they can't look up applications with the serial number and part number you gave me, but I guess they don't have a way to find that out?

Anyways, if you can get back with me with that info I can relay it back to them and see what part it is that you're needing.
