I have rough country 50" light bar. I got this installed at the dealership as it was part of a deal of buying the truck. I love it but it NEVER stops whistling. Ive tried everything. I bought wind isolators, and have bought insulation pieces. Whistling starts at 20 MPH and never stops! I can tilt it really high up for it to stop but then it looks retarded. Please any tips I will take. I love my new ram rebel but this is driving me nuts.

Try a hood deflector. Might work as it would deflect most air upwards and away from windshield.

Very nice. I have n-fab brackets and a pro comp might bar. Think I'm gonna sell both though. Just not feeling it now.

I had the same problem when I installed my 50" KC bar, it almost sounded like a dremel tool inside the cab going down the highway. I'm using a SoCal Supertrucks mount which has similar placement to your mount putting the center of the bar close to the windshield/cab centerline. While this looks cool, it also creates a high vortex area which creates a lot of noise.
I know, not a Ram, but the physics remains the same.

Instead of foam try this, to isolate the fins buy a couple feet of 3/8" rubber fuel hose. Cut it into 3" sections and then take each of those section and slice it length wise into quarters (so you have four 3" strips)

Now starting at one end of the bar insert a strip inbetween the fins (skip every other fin and you shouldn't need any adhesive), then go down 10-12" and insert more strips except do the opposite fins of the previous. Alternate and do this across the back of the light bar. This will keep the fins from resonating.

Also, from your pics, it looks like you have the bar aimed upwards, that will make the noise a lot worse. Aim it to that it is parallel to the ground to start and then start adjusting it upwards in small increments until you get it high enough with minimal noise.

I can snap some pics of mine up close if you'd like.

You're never going to get rid of all the wind noise, but you can minimize it.

Any updates?

Thanks man! One of these days after people are used to me being around I may post up a picture thread of my trucks.

As much work as I've done ontrucks some would think I owned a customization shop...might have missed a calling. II just sold a truck for nearly 8k more than MSRP becuase they enjoyed how "original" the customization looked. Always try and do a fine balance between stocck and aftermarket look.

This may be a ridiculous comment, but I've never had one of these, is there any possibility of mounting at the rear of the cab without diminishing looks or functionality of the light?

Not really.

I believe the whistling sound can be remove by adding a wind deflector just like this.

I will admit I've never seen this idea. Be interesting to know if it works.

Any chance you could snap some pics?

I'm sorry man, I never saw your request. If you still would like to see the picture I can snap a couple.

Good video.
