    Video Review & Installation

    I'm Ryan from and this is my review of the FOX 2.0 Adventure Series Shocks fitting all 2007 and up JKs with four to six inches of lift. Today we're going to talk through the installation of this shock which, of course, is a very simple one out of three wrenches. This will bolt directly in place with your factory shock or any aftermarket shock that you have and the install, again, is very, very simple. We're also going to talk about the construction and the few of the features of the shock.The shocks you run on your Jeep is going to have a huge impact on your ride quality, your handling, and just the drive ability of your Jeep. So in my opinion, shocks are not somewhere that you want to skim on price. FOX is known for making a really high quality shock, they've cut their teeth building shocks for race trucks and other race vehicles and they take that technology. And they know how and they put it into a shock that you can buy for your Jeep.Now, the Adventure Series that we're looking at here is a slightly lower end shock from FOX. It is going to save you a couple of dollars over some of those other shocks that you can purchase from FOX. This is going to be a powder coated shock as opposed to a high-grade aluminum or even a slightly lower grade aluminum alloy that is clear coated but as far as the internals, the valving, the bushings, the rest of the shock, this is still going to be a high-quality shock that's going to give you a really high quality ride all while saving a few dollars off of that top tier FOX shock.This shock is a two-inch seamless alloy smooth body shock. This has a five eights inch chrome hardened shaft that is going to give you a lot of strength. This has nitrite bushings in both ends which are going to be quiet but also hold up really well and this is going to be valved properly for your Jeep as much as a shock can be when it's coming right out of the box.Now, of course, if you get your shocks custom valved, they're going to be perfect for your spring rate and for the weight of your vehicle but FOX does a really nice job of building a shock that right out of the box is going to ride really comfortably and perform really, really well.Now, there are a couple of different types of shocks on the market. There are hydraulic shocks and there are nitrogen charged shocks. There is fluid in any type of shock and when you work the shock really hard, that fluid can bubble up and cause some cavitation and eventually shock feed where the shock doesn't work quite as well anymore. So the nitrogen charge in a shock like this is designed to eliminate that cavitation and that bubbling ensuring that the shock is going to continue to ride well even when it's worked really hard.Now, most of us aren't doing high speed desert racing. We're not working a shock that hard where we absolutely need a nitrogen charged shock. However, the benefits of a nitrogen charge are good to have. In general, a nitro shock will ride a little bit harder than a hydraulic shock because it does have that charge built into it but ultimately, it's the valving of the shock that controls the comfort. So this is going to be a nitrogen charged shock that is still going to ride really comfortably and provide top quality handling on the road and off-road.To get this shock installed, as I said before, is a very simple one out of three wrenches. All you're going to need to do is remove the top and bottom bolt that's holding your chock into place and take the factory shock out, put the new shock in with all of the factory hardware. Now, in the rear, you're going to have two bolts up top, one in the bottom. In the front, you're just going to have a nut that goes onto the threaded shaft of the shock up top and a bolt in the bottom. The only thing that can make this slightly difficult is up front on that top shock nut. That can be a little bit difficult to get to and they can be a little bit rusty so I would definitely recommend spraying all of those nuts and bolts well ahead of time with penetrating oil. Worst case scenario, if you can't get to that top shock nut and get it loosened up, if you put enough force on it, it'll break off. You're throwing away those shocks anyway. It's not really going to matter and it'll be a lot easier than trying to get it off in once piece. There just isn't a lot of space in there. You can't really get a tool in there.Other than that, again, very, very simple installation. You're just going to need your traditional hand tools, a bit of penetrating oil. And as far as time goes, you could probably install a shock in less than 15 minutes, probably about an hour for all four of them. This is not going to be a very difficult install at all.When it comes to the value that you're getting for the price, I think that this shock is a really good value. This is going to be less expensive than other FOX 2.0 shocks and there really isn't a big difference in the internals and the way that this performs and the way that this acts as a shock. So I think it's a good deal. It saves you some money over some of those top-quality shocks from FOX but you still get all of the internals, you still get the FOX name, you still get a shock that's going to provide a really comfortable ride.Now, even at the lower price by comparison to top quality FOX shocks, this is still going to be an expensive shock when you consider all of the budget shocks on the market. But as I said in the beginning, I think that shocks are not a place to skimp if you want your Jeep to still ride comfortably. There's nothing inherent about a Jeep that makes it ride poorly other than the slightly shorter wheel base. Even if you have a big, lifted Jeep on big tires, it can still handle and ride well if you have the right shocks on it and getting a high-quality shock from FOX is one way to do that.So if you're looking to get a comfortable ride and quality handling out of your Jeep, these FOX Adventure Shocks are a great way to save a little bit of money over those top-quality FOX shocks but still get a really nice shock. So that's my review of the FOX 2.0 Adventure Series Shock fitting all 2007 and up JKs that you can find right here at
