      • 4 Point Removable Harness
      • Ideal for Track and Street Use
      • ASM - Anti SubMarining Technology
      • Works with Factory Seat Belt Receptacles
      • 2" Wide Red Polyester Webbing
      • Fits All 2005-2017 Mustangs


      Four Point Removable Harness. If you love running your Mustang at the track, but it's also your daily driver you need a Schroth Quick Fit Four Point Removable Harness. The Quick Fit 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 interior for people or cargo on the street.

      ASM Technology. The Schroth Quick Fit 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 works with your Mustangs existing factory seats and safety restraint system allowing for easily installation and removal. The Quick Fit 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 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.

        Installation not good

        The anchor on driver side did not specify you had to cut the plastic cover over the anchor a slot so that you can get the anchor in and bolted down

        Should have came with the RECARO seats.

        No instructions in the box . Found a YouTube video that puts you in the right direction. Fit and install looks great haven't had a dry day to try them out.

        Schroth quick fit harness

        It took about 2 hours to install on my 2015 GT. The back seat mounting was pretty easy. Although there was some bending involved to line up where the straps had to b. The front was tough. Had to drill the hole to fit onto the bolt that it secures to. Some bending there too. But after that the belts fit great. Feel great. Very snug in the drivers seat. Love the look too

        Everyone should have these

        Amazing fit, easy installation and I find them more comfortable then the 3 points. You have to make one small adjustment to one connector but it's easy enough. Love the look even for off the track.

      Questions & Answers (5 answers)

      5 Top Rated Questions

      In the installation video, it seems that these could be simply detached from the factory female buckle points, rolled up, and laid in the back floorboard if people needed to ride in the back. Is that true, or would you need to completely remove them before using the back seats?

      What changed with the 2018 update that these won’t work in the new S550 cars?

      If installed, can the stock seat belts in the front and back still be used?

      • The Schroth QuickFit Harness will connect via the female buckles in the rear, making their use impossible without removal of the quick fit harness. The front OEM female buckles are also used as an attachment point.

      How do I use these with a Corbeau harness bar? I dont know how I would attach them to the bar instead of the rear seat belts.

      • Unfortunately, the Schroth QuickFit Harness would not be able to attach to the Corbeau Seat Belt Harness Bar. The Schroth harness's are specifically designed to work with the factory seats and safety restraint system.

      Does this require a harness bar given that the car is equipped with recaro seats?

      • No, the Schroth QuickFit Harness clicks into the car's female seat belt receptacles and anchors to the factory seatbelt points.
