    Wind deflector and all necessary installation hardware
Fork-Mount Wind Deflector is rated 4.3 out of 5 by 38.
Rated 5 out of 5 by from Deflectors work and appearance is good, too. Reduces wind buffeting. Good deal, especially in cool weather. Installation is easy if you remove and install bottom bolts first (only hand snugged), then the top bolts. Then tighten. Done this way the installation will not take more than 30 minutes. Should you try to install top bolt first, or remove both bolts on a side at the same time, you will face additional installation difficulty.

Rated 5 out of 5 by from Awesome I put these on my 2012 Heritage and they work great. In cool weather I use the soft lowers and with the combination of the two of them there is almost zero buffeting. By their self they do cut down a great bit on the wind

Rated 5 out of 5 by from does what I want and looks great too these were easy to install in less than 30 min. Most of that time was spent getting ready to do the work. They look great too. On my first ride I noticed the difference right away, they take away the beating wind but still allows me to be in the wind. Love them!

Rated 5 out of 5 by from Great look, great product. Super simple install, just a little common sense and stay calm. Took about 20 minutes, parts fit perfectly. If you do not think they fit, reverse them from what you think they should be. The pieces actually should curve FORWARD away from the rider, not backwards. Great addition to my heritage.

will these work with the fork mounted tie down brackets

My wife's 2013 Fatboy has fork mounted tie down brackets with the detachable nostalgia windshield will these work with them or would I have to remove the tie down brackets?

Use with 49004-00A Engine Guard

Will these interfere with the engine guard on a 2016 FLSTC at all? I'm leery of them hitting the guard at full turn.
Asked by: jbpeace
Hi Jbpeace, Assuming you have the OEM on your 2016 FLSTC---they should definitely work. Thanks!

Proper mounting on FLSTFB with Nostalgic Q/D Windshield

I have a 2014 FLSTFB FatBoy Lo with Passing lamps and a removable Nostalgic Windshield. The directions show the detachable windshield is mounted between the passing lamp bracket and forks. They also state that the wind deflectors be mounted on the outside of the docking points. Looking at my Lo, this is not possible and the directions do not help. The wire lock for the Nostalgic windshield clips to a stud on the outside end of the mounting bolt. Can you please provide better instructions with proper diagrams? Please help.

Hey There Gommee! We suggest that if the instructions are unclear to you to please see your dealer for further assistance with installation.

will the front fork wind deflecters fit a 2oo5 soft tail deluxe

Asked by: yauncy2005
Hello Yauncy2005, PN 57400143 will not fit your 2005 FLSTN. It only fits 1993-1996 FLSTN's. Thank you!

Do they mount tight to the forks?

I have a 2014 Softail Slim with the detachable windshield. The directions say on models 2000 and newer to mount the deflectors outside the w/s docking mounts. This would put the deflectors an inch out from the forks which would look pretty dorky. Will the windshield fit back on if you mount them up against the forks? I think you could switch out the spacers for washers to keep the distance the same for the w/s mounts. Thanks.
Asked by: DSlimRyder
When it comes to the instructions on our I-Sheets, it's the engineers that validate the fitment and the proper ways to install. So we really can't recommend deviating from what's been noted.
