Looking For Replacement Side Rails Without T-slots For My Retrax Cover
Updated 12/08/2025 | Published 11/20/2025
Question:
Picked up a second hand Retrax xr, serial 23080785063007. Can the t-slot rails be replaced with non t-slot rails? Truck is a 2025 GMC 3500 with a 69 bed 82.3 What is the part number as well as a replacement lock assy.

Hey Dennis,
I actually went ahead and reached out to Retrax directly for some more information on that cover to find the right rails. The correct replacement rails you are going to want to go with for your specific cover are going to be the replacement side rails # RTX27FR. The kit includes both side rails and all necessary clamps and hardware to reinstall.
How have you been liking the cover so far?
