What Replacement Rails Do I Need to Use My RetraxPRO MX on My New 2021 Ram 3500?

Published 10/04/2021

Question:

Unfortunately my truck, 2021 GMC Sierra 3500 long bed was totaled in an accident. I was unable to get the same truck. But my RetraxPro MX survived. I was able to get another truck with the current shortage, but it was a 2021 Ram 3500 long bed. I would like to just get replacement rails for my current RetraxPro instead of buying a whole new system. Do you sell the rails that will fit the new Ram 3500?

I have a solution for you. I confirmed with my tech at Retrax that the RetraxPRO MX # RT80485 (designed to fit your 2021 GMC Sierra 3500 with an 8-ft. bed) is different in several ways than the RetraxPRO MX RT80237 (designed to fit a 2021 Ram 3500 with an 8-ft. bed). For example, there is a 1/8 inch difference between the bed lengths. Another difference is the width of the beds and the tailgate measurements.

With these differences, even if we could provide different replacement rails to make your cover work with your new 2021 Ram 3500, you would still need many more parts to accommodate the differences in the dimensions. With that being said, I recommend getting the RetraxPRO MX RT80237 for your new truck. This is the most economic option as well as the most assured way to get the cover installed the quickest (since we will not have to troubleshoot and discover all of the individual parts you need).
