Was looking for something specific- gave them a call and was able to order it up, even though it was not on the website.

Boyfriend and I both have a set of the 2.5’ whips for our jeeps and use them every chance we get. They look for show and work even better for light in camp and on the trails. They bolt up similar to a radio antenna and have a quick release feature that we have never seen before but absolutely love. Definitely top 5 favorite accessories we’ve bought for our jeeps, and customer service is just as great as their products!
