Question:

I have a retrax cover on my Ford Powerboost F-150. It has Serial 20090430794015 . No model. It was factory from Ford I think. I need to know if the replacement T-slot rails will work on it. 5.5 bed.

Hello Rad, thanks for reaching out. Yes, the Replacement Side Rails for Retrax XR Series Hard Tonneau Covers # RTT-82381 are indeed for the 5.5' bed.

I do not have a way to look up your serial number to confirm fitment though. If you contact Retrax directly they would be able to look that up. I can tell you the # RTT-82381 rails fit the following covers:

RetraxONE XR: T-60381
PowertraxONE XR: T-70381
RetraxPRO XR: T-80381
PowertraxPRO XR: T-90381

Please let me know if there is anything else I can do to help.

Hey Rad, did you get a chance to contact Retrax to confirm the fitment of the T-slot rails for your Ford Powerboost F-150? I'm asking because your experience could help others with similar setups.
