Long LED Light bars can resonate in the wind. If you are experiencing a lot of wind noise from your large LED Light bars, it could be from the cooling fin resonance (vibration) from the wind. These isolators snap in between the cooling fins to stop the vibrating resonance noise. We recommend 1 every 10" or so. Made from non-hardening rubber. Made to fit our XX-Series, MX-Series, CX-Series light bars only.
These are a perfect fit with no modifications required.
Warning! They fit very tight, so you will have to wrestle them in a bit, but hey, you're no sissy! You can take 'em!
