Some of those roller fairleads have a larger diameter bottom roller for use when using a snow plow blade which can make the cable loop & swage hard to fit through the gap in the rollers without removing the roller pin end circlip and roller. The larger bottom roller allow the steel winch cable a larger radius to run over when lifting & lowering the plow blade.
Those are actually off of a Can Am Defender. I did do a video on it but I never posted it. Will have to find it and post. No rubbing and I was surprised when I put them on. Took it to Royal Blue in Tennessee, didn't have any problems. Gave me an inch more clearance.
