Does Roadmaster Rear Sway Bar part # RM-1139-177 Fit 2020 Ford F-150
Updated 10/27/2025 | Published 03/17/2025 >
Question:
The Roadmaster site says that the 1139-177 will fit a 2020 F150 but your site doesnt? One of the previous purchasers seemed to state there are 2 different frame brackets I would think for 2014 and prior vs 2015 and up. They only give this part number for all years up to 2020 which is what I have. If it will work Id like to order off you guys since you seem to have one in stock and ship quickly. Thanks much

Hey Joe, we get all of our fit info from Roadmaster so if they are showing the part # RM-1139-177 as a fit for your 2020 Ford F-150 then it does for sure fit as they would be the authority on this. We try to make sure our fitguide is as accurate as possible but occasionally we do have to make some corrections so thank you for noticing this and bringing it to our attention.
