Question: Hi.  I'm having trouble....where do I find the appropriate cross bars???  I need to carry 2 kayaks, so I though flat on cross cars would work well. Additionally, I have a short garage.  How much does this rack add to the height above the roof (without lights)?
Document: This rack fit my needs exactly in that I wanted a versatile design that could be configured to carry everything from plywood to a boat and even attach a cargo rack or roof mounted tent. The built in light bar is an added bonus and really makes the base rack even more functional--not to mention it looks great.The Sherpa rack is very well made and compliments the lines of the jeep. The materials used in the design and the finish on the rack are impressive.
This rack is top of the line. I looked at other racks but the ability to still take the hard top off with just a couple of very simple steps and shazam, the top is off. It fit perfectly with very little effort. You will need to drill two holes in the frame for the brackets/mounts on the rear but that was the most difficult part. Its beefy, sturdy and squeak free if you add a sealant/silicone around the seams before install.
I'm very happy with the quality of the rack. It fit my 2014 Wrangler Unlimited quite well and looks great. I don't give it 5 stars because the instructions while clear enough, omit several items that are included in the kit. It's not hard to figure out where the pieces go, but it really should be spelled out clearly. Also, a few of the holes in the tubes did not line up correctly.
Use this to haul my kayaks around. Item arrived in a serverly damaged packaging. I was shock when I saw it at first. Did an inventory and all parts were present and in good condition. Only complaint is with a soft top is the amount of wind noise you get. I'm used to it now, but does get annoying on long trips.
Bought these racks after much researching the pros and cons of similar racks. I went with these because you don't need to do anything to them to remove the Freedom panels, and they tilt back to allow soft top to be folded up and down or to take hard top off. No need to disassemble them like some of the other racks, this is a plus if you plan on putting a cargo basket on top.
It works perfectly well with my Rugged Ridge Snorkel too. I highly recommend this item to anyone looking at adding a rack and not wanting to break the bank.
I would recommend this product as I really like it. I just want people who read my review to know they may experience a few minor issues during the install, most of which would be fixed with better instructions.
Quality of the materials and design are great, 4 star rating for the directions being not all that clear but easy enough to figure out. The integrated light tabs on the front are a plus as well. If you have taillight guards on the racks will clear them, but the bumpers that keep the racks from swaying won't so you will need to remove guards or drill new holes for bumpers.
Amazon's price was fantastic! I will say that the bars appear beefier than the picture represents. I have a four door 2007 Jeep Wrangler/Sahara Unlimited.
