Here’s what the Front Runner fairing looks like on mine:
When it’s touching the cab, the rubber edge squeaks like crazy because the bed flexes relative to the cab. I’m working on replacing the metal fairing piece with some ABS plastic cut to a taller dimension so it sits at a lower angle and functions less as a speed brake. I’ll put some felt along the edge so it doesn’t squeak anymore too. The Front Runner hardware is great though because it’s adjustable and has no issues with the front track.
If anyone is interested in the metal fairing piece let me know. I won’t have any use for it once I fab the new one. I’m keeping the hardware though.
