Great upgrade to the jeep.
This was a great upgrade. I made my own roofrack that bolts to the backbone system. And the braces inside that transfer the weight to the body are nice to hang stuff from and use them to secure camping gear. I used butyl to seal the holes in the hardtop and haven't had any leaks.

Typical Rhino Rack gear...Awesome!
I can't say enough how much I love my Rhino Rack setup. It's a bit on the pricey side, but 100% worth the investment. You won't be disappointed in both the build quality and the fit and finish on your vehicle. For my 21 Wrangler, I wanted something trimlined so nothing gets caught up in the trails as I live in Vancouver, Canada. The trails are thin and things get caught up all the time, let alone getting the BC Pinstripes. This keeps your gear inside the lines of your Jeep and is super tough. Highly recommend!

Awesome product.
Fantastic product. Very well-designed. Not too difficult to install. If you're looking for a strong sleep design, this is what you need.
