I have currently a 2022 Rubicon with the extreme recon package currently in shipping, I had these with my 2020 2dr Rubicon, just wondering in the xl size will they work with the plastic bumpers, I will be replacing my plastic bumpers with aftermarket ones, so I am not sure will they still work, my 2020 Rubicon had the factory steel bumpers they definitely worked with that oneYes you need flaps. Rock Blox XLs work well and line up perfectly with the XR’s flare extensions.
This won’t stop all chips — your rear fenders are gonna take a beating pretty much no matter what — but it does greatly reduce them on the doors and hinges.
