ZROADZNoise Cancelling Wind Diffuser, Black, Aluminum for 40 Inch Straight Double Row LED Light Bar (Z330040S)

Does not eliminate 100% of the wind noise if that is what you are looking for, but reduces it drastically to make it tolerable. Little bit of a pain to install just because you have to drill into your light bar. Make sure you have a rivet tool.

Night and day difference! I have a straight light bar from another company on my Jeep Wrangler. It was extremely loud even cruising on side streets. My ears and head would hurt due to how loud it was. My husband installed this and instantly a huge difference! I highly recommend it!

I was skeptical purchasing.. Many friends have the AeroLidz but I don't like how it looks so I took a chance on the ZROADZ Wind Diffuser. I am glad I did! It eliminates about 95% of the whistle (my mud tires conceal the remaining noise) and you can't even tell its installed, maintaining the look you were after when you installed the light bar (no bulky plastic over it).

I dislike how it’s designed to be riveted to the bar. Definitely don’t want to drill holes in my light bar. So I used JB weld to hold it in place. It does the job but is way overpriced for what it is.

Was supposed to be for a 50”. Measured 52” and was bent when received it

I have been searching high and low for something to get rid of the whistling from my light bar since last November and came upon this and I am soooo happy I did. What a world of difference because there is no noise at all anymore

Easy to install and they look amazing

This thing reduced the wind noise on my daughter’s jeep so much. I would definitely recommend it.

Product does not work still have a lot of wind noise
