What a terrible design. Mine came short on hardware and the instructions are less than helpful. The rack is out of square and I cant even get it to line up with using two people as the instructions suggest (both people are over 6' tall and 200 lbs). on top of that for the price point there are several areas where Teraflex could have saved the consumer time and frustration and assembled it themselves. There is a rail system that goes all the way around the main rack with a worse design than most IKEA builds. Overall I am less than happy with the rack, next time think about the end user and make sure you are putting out something that can be assembled at home and not need to be taken apart and reassembled in a shop for an additional cost. I run several Teraflex parts on my Jeep and thy have all been quality parts but this one is a huge flop!

Just got done installing one of these bad boys. I can say it is beefy and for the 75lb rating way over built. Looks to be well thought out and powder coating was excellent. I think if I could have a hand in designing it I would have made it a bit lighter which if you are going to stay at the 75lb weight rating that should be fairly easy to do and the biggest thing I would change would be I would make it so there was a bit better rear view visibility again with the 75lb Rating I think it could be done. I still am going to give it a 5 star rating because it is closer to 5 stars than to 4 stars. My real rating would be 4.75 stars LOL>

I've had this rack on my Jeep now about a year. All I can say that this thing is over engineered and rock sold. Putting it together, took some patience but in the end you have one quality piece. It is a bit heavier than what I thought it was going to be, but still not disappointed.
