    Hey, everybody. I'm Justin with, and this is my detailed review of the Schroth QuickFit Pro Harness, available in your choice of either black or red, fitting all 2005 and newer Mustangs. You should be checking out the Schroth QuickFit Pro Harness if you're serious about the safety in your daily driven or weekend warrior Mustang and subject it to a good amount of track duty. When I say "track duty" in this case, guys, I'm more talking about the road course stuff or SCCA-type racing, as opposed to all out drag racing. Now, those drag racers might want to entertain the idea of a five or six-point harness, depending on the rules in your respective class. Taking safety even further here, guys, the Schroth QuickFit Pro is actually the first four-point harness of its kind that can be used with a HANS device along with the factory seats. If you aren't aware, HANS stands for head and neck support device, and it's something used in a wide variety of motor sports just to prevent any head or neck injuries in the event of a crash. So again, if you really push the car hard on the track, this is a great option for you guys if you want to make safety a top priority. Now, Schroth has been one of the leaders in aftermarket restraints and harnesses ever since the early '90s. And besides the work they do in the automotive field, also supply stuff for airplanes and helicopters, along with ballistics, seating, and restraints for the military. So essentially, these guys know what they're doing and they're trusted by a lot of people. All right, guys. So the QuickFit Pro is the next generation of Schroth's very popular QuickFit series. This design is very popular, because it's going to integrate into your existing Mustang safety features without the need for anything else. So you don't need an additional harness bar. You don't need a roll cage to use this thing. Basically, it just plugs in or utilizes the factory mounting points of your Mustang seat belt. And again, I think that's what's going to make this very popular to a lot of you guys at home. Here's my one and only nitpick with this mounting system. Now, ideally, you'd like to have the shoulder harness between 0 and 20 degrees downward of the shoulder on a horizontal plane. Usually, using a harness bar, or a lateral bar of a roll cage would be the best way to help you achieve this. Using Schroth's method for the shoulder harness, you're actually approaching the angle of 45 degrees, which is acceptable but not necessarily ideal in my eyes. Again, you never really just want to mount the shoulder harness directly behind the seat to the floor, because that can cause an injury in the event of a crash. Shoulder mounting aside, I really do enjoy how the Schroth integrates into the factory seat belt and restraint system, and here's why. For starters, it's going to silence that seat belt warning chime that you might otherwise hear if you left the seat belt unplugged, for instance, or maybe if you went with a different harness option instead. The Schroth is also going to utilize the factory pre-tensioner system for the lap belt portion, which is pretty cool. Because in the factory system, there's actually a little pyrotechnic device that will ignite in the event of an accident, and that's what tightens up your lap belt in a hurry. The fact that the Schroth is going to reuse that is actually very cool. Sticking with the lap belt portion, guys, the Schroth harness actually incorporates what they call ASM Technology, or Anti-Submarining Technology. That's basically going to help prevent you from sliding or submarining underneath the lap belt portion here in the event of a collision. Now, this might be a concern for some of you guys out there going with a four-point over a five or six-point harness that typically has a belt or belts that come up between the legs, preventing the submarining motion from even occurring. All right, guys. Let's get into the harness here, because there are a few things to talk about. First and foremost, Schroth does offer the QuickFit Pro in both red or black. You can see we have the red here on the table. It does feature two-inch wide polyester webbing, and that's going to be a little bit better than the nylon material when it comes to converting the energy of a crash, or soaking up the energy itself. The Schroth also features a monofilament that's woven laterally into the harness itself, and they say that's going to help better spread the load of the impact over the entire harness. At the mid-$300 price point, the Schroth QuickFit Pro is definitely going to be one of your more premium harness options available here at It's going to cost you about $100 more than the standard QuickFit. But keep in mind, guys, this is the only four-point option currently available that can be used with that HANS device, along with your factory seating, and you're also getting the convenient mounting locations. As I just mentioned, guys, one of the benefits going with the Schroth QuickFit Pro here is that you don't need any extras when getting it installed into your Mustang. No harness bar, no roll cage, no race seats, no modification, and best of all no drilling. Instead, this thing does mount fully into your ride using the existing factory seat belt locations. You will need some basic hand tools to remove some of the factory seat belt stuff, replace it with the Schroth stuff here. But overall, a very simple install, one out of three wrenches on my Overall Difficulty Meter. We call it an hour on the site, but I wouldn't be surprised if it takes you less than that. I feel like the Schroth QuickFit Pro will be a solid option for many Mustang owners out there for the simple reasons that it's easy to install, you don't need anything extra to get it installed, and best of all it's going to provide some extra safety in your street driven or track Mustang, more so if you take advantage of the HANS support. Now, it's tough to put a price on safety. Some people might have a slight issue with the $300 to $400 price tag. But overall, you're getting a solid, well-engineered product that's going to offer you some things other options will not. So be sure to check out a Schroth option for your ride, right here at

    Four Point Removable Harness. If your Mustang pulls double duty on the street and at the track you need a Schroth Quick Fit Pro Four Point Removable Harness. The Quick Fit Pro will keep you securely behind the wheel of your Pony while you're carving corners at the track. Then it can be easily removed giving you full access to your Mustangs interior for people or cargo when back on the street.

    HANS Device Compatible Schroth's Quick Fit Pro is the world's first 4 point harness that was designed to be used in conjunction with a HANS (Head and Neck Support) Device and your factory seats. Traditional 4 point restraints do not join at a center point, they are sewn to the lap belt leaving almost a 6" to 8" separation between them. The Quick Fit Pro is designed in such a way that both shoulder belts angle in towards the Cam Lock easily facilitating the use a HANS Device.

    ASM Technology. The Schroth Quick Fit Pro features Anti-Submarining (ASM) Technology that positions the lap belt low across the pelvis. This keeps your hips and back side firmly planted in the seat preventing you from sliding under the lap belt in the event of a collision.

    Works with Factory Safety Restraint System. The Schroth Quick Fit Pro works with your Mustangs existing factory seats and safety restraint system allowing for easily installation and removal. The Quick Fit Pro clicks into the car's female seat belt receptacles and anchors to the factory points which are load tested to withstand a 3,000-pound force for 6 seconds. By using the stock seat belt receptacles the vehicle is aware that a person is seated and restrained, silencing the warning chime as well as taking full advantage of the factory seat belt pre-tensioner.

    Polyester Webbing. Schroth's Harness Belts are made from 2" wide polyester webbing. Engineered with “memory effect” Schroth's polyester webbing features special mono filaments laterally woven in, that perform like small leaf springs to keep the webbing flat. This results in better load spreading over the full width of the webbing. Polyester webbing also has a better force/elongation ratio, when compared to standard Polyamide (NYLON®) webbing, so it can convert more energy during an accident.

    Application. This Schroth QuickFit Pro 4-Point Red Harness is designed to fit all 2005 to 2017 Mustangs with the factory seats and safety restraint system. Including the V6, EcoBoost, GT, Bullitt, BOSS, Shelby GT500 and Shelby GT350 models. Available individually or as a set of two. Please select from the options listed above.

        As some females are not comfortable wearing a harness If installed on the passenger seat can the factory shoulder belt still be used without un-installing the harness....meaning can she choose between using the harness or factory belt?

        • Either the factory shoulder belt or this harness must be used, the factory belt cannot be used without first uninstalling the harness.

        Will this fit a big guy? I’m 6 1 275lbs.

        • The Schroth QuickFit Pro Harness is designed to provide fitment for the majority of drivers out there. Unfortunately everyone carries their weight differently, so we are unable to really tell if this will or will not work well with any given person.

        Can this be run without a HANS device at least initially. Or is something else needed to not run a HANS

        • It's indeed compatible with a HANS device, however it is not necessary. This can be installed just fine without it.

            This was a very quick and efficient install. All of the required equipment was included and I had it installed in my 2017 GT350 in about an hour. Easy to remove when you want and great security when you are buckled in.

            These are amazing. Helped me at the track when I was exploring the limits of the car. These are a great help to strap you into the car without moving like the factory seatbelt.

            Did not fit my 2017 350GT,

            These seat belts do not go in a 2017 350GT without major disassembly of the interior and cutting of plastic. Was very disappointed because I spoke to Yasheem and he assured me that they would work.

            Wearing your mustang

            As the title says, it's like wearing your mustang. As much as I love my leather interior, at the track it's unfortunately too slippery and I often need to reposition or hold myself in or after turns. This harness fixes that, short of having race buckets. Easy to install and effective in letting the driver concentrate on the task at hand. I will recommend finding out if SCCA, NASA or CASC time trial events will permit their use without a roll bar, if you are a competitive road course driver like myself.

            Great Fathers Day Present

            I got both left and right belts for Fathers Day. It took about 30 minutes to install. Two things you need to have/know. It takes a T50 torx bit to unbolt your mustang seat belts. It's not common in a typical tool box. But they cost less than $2 at your local hardware store. The second this is you need to bend and twist one part of the straps to properly fit in the rear seat mounting point. The directions are clear but getting the right bend took a little for the first one. I love the fit and feel. It anchors you in your seat and I always hated the way the standard belt rubbed my neck. I drive my Shelby GT500 very aggressively. These keep me in the seat.

            Schroth quick fit pro harness review

            Fairly simple to install onto the bolts found by the stock seat belt buckles. Took 30 mins to install with two people and minimal tools. Fits well and fastens easily for added seat belt retention. The center clip digs in a little against the driver's stomach but only a slight nuisance after extended driving. Otherwise works very well for a quick-detach 4pt harness. 4/5 stars simply because it digs in a little and isn't the most comfortable harness available.

            LOVE IT!

            The reason I purchased these Schroth QuickFit Pro Harness is because I am now supercharged and felt it was time for an upgrade. I just didn't like the stock seat belts would do me justice. These new ones however feel awesome. They literally take like 15 minutes to install and you can keep your stock seat belts installed too if you have a full car. They are comfortable around the neck as long as you adjust them correctly. Took me a little bit to get the hang of it. Also for those females that don't like seat belts going over their chest because its uncomfortable you will love these.

            Track day

            I had my new harness installed at my local Ford Dealer. Attended a Performance Driving Clinic at Buttonwillow Raceway. After a secession with the instructor, I hooked up my new four harness and went out on the track on my own. I have been on that track before but this time I stayed in my seat. Was easy to get in and out of. Felt much more secure on the track. DesertBum
