    Video Review & Installation

    This Kargo Master lo-pro mod-rack system is for those of you that have a four-door JK, that has a hard top on it, that are looking for one of the lowest profiling and, in my opinion, the sleekest looking roof racks you can get for your JK. This system is going to come with a front hoop. It's going to come with the runners that go from in front of the Jeep toward the back of the Jeep. And, it's gonna come with this floor section to make a very useful roof rack. But, because of the way this system is designed, it will drill through your roof rack and use your sport cage as the support in the rear, so you don't have to have a rear hoop. This system also has this flooring section that really, more or less, hangs below the roof rack, instead of sitting up on top of it. Again, making this really sleek and really low profile. Those bars that run from the front hoop toward the back of the Jeep follow the contours of your hard top very, very well. Again, just adding to that sleek look. It's going to be very, very functional because it will still allow you to remove those freedom panels even with the roof rack in place. And, because you have this floor system, you're gonna be able to put things on the roof rack that are very, very small where otherwise, with a more open rail roof rack, you wouldn't be able to do that. So, this system has a lot of features that I really do like. However, for some of you, the price tag might be a little bit too much for the low profile, for the strength, for the fact that it's a very complete system. This is gonna hold up very well, not making any sort of rattles or noise, not rust. You are going to be paying a bit of a premium. So, if you're somebody who has a four-door JK with a hard top and you leave your hard top on all the time, you want a very sleek roof rack and you have the budget for it, I think this is gonna be a really nice option. So, as far as construction goes, this is as I said before, very, very strong. It's gonna be two-inch tubing. This is a new marine gray black powder coat finish that's gonna hold up really well. Again, no rust, no creaks, no noise, no rattles like you can get out of the more budget roof racks that are on the market. One very important thing to note, as I mentioned before, this is designed to drill through your factory hard top, so If you're not comfortable with doing that, you're not comfortable with having that done by somebody else, if you take this somewhere for install then, this is not going to be the rack for you. Now, Kargo Master does have other racks that have a rear hoop that don't drill through the hard top. So, one of those options would probably be a better choice. But, if you're looking for that really sleek look, deleting that rear bar, having this drilled through the hard top, in my opinion, is really good as it looks. Now, the front hoop thing that you get in this system has the ability to mount some lights on it. It does have a little bit more of a safari look. It's also a very utility piece. And Kargo Master, builds all of their parts to be very modular, so you can always add on to what you currently have. Get some additional mount, some additional parts and pieces that you can put onto that front hoop and on to the rest of the roof rack, if you decide that you wanna add to it. As for the install of this roof rack, I am gonna give this a three out of three wrenches and that's because you are drilling directly through your hard top. So, there are a lot of things that can go wrong there. You wanna make sure you're drilling in the right spot, so that you're not patching up holes and then, the holes that you do drill, you're gonna have to make sure that they are completely weather proof to ensure you're not going to have any leaks. So, this is going to be a little bit more of a difficult installation. Give yourself three to four hours to get this installed. But, if you do decide to tackle it yourself, it can be done in your driveway. You just wanna measure two, three, four times before drilling those holes through your hard top. So, the front hoop is a very easy installation. You're just gonna remove a couple of the torx bolts from your windshield hinges, and attach that front hoop as you would with a lot of other light bars and lot of other roof rack systems, then you're going to be able to attach your upper section onto your roof rack, you're gonna have those side bars that you can attach, and that's going to index where you're going to drill the holes. There are some brackets that you'll need to put on the other side of your top to add some additional support from the support cage through the top into your roof rack and finally, you're going to be attaching this flooring system onto your newly installed rack. At $1300, this is one of the more expensive roof rack systems that you can get on the market. Now, I would compare this to something like a Garvin system. Garvin also makes a very low profile, very stylish rack, in my opinion. However, this is even going to be more sleek, even more low profile because it doesn't have that rear hoops. That's what kind of sets it apart. As for those Garvin racks, are going to be in the same price range as this rack here. So, this isn't as astronomical and let's not completely out of question, but this is going to be that upper impression on that premium rack, as far as quality, price, and the features that you're going to get along with that. You just have to know that going into it. If all you're looking for is an inexpensive direct rack to throw a kayak up on top of, you can get away for $300 or less with some of the more budget friendly racks, and those are available as well. So, if you're looking for a very functional, very high quality and low profile roof rack, I would definitely recommend taking a look at this one from Kargo Master and you can find it right here at

It offers unparalleled protection for your windshield assembly and provides a great attachment point for optional grab rails, standoff brackets and light mounts. The front-to-back rails are formed of 1-5/8-inch tubing with CNC-machined clamps and provide great attachment points for other accessories. The MOD-RAK itself is made of sturdy, modular aluminum panels. All parts are finished with a special blend of zinc-epoxy primer and black powdercoating. This system will provide years of trouble-free use and will look good while doing it.
