Features & Details

  • Line Lock System
  • Great for Drag Nights
  • Protects Rear Brakes
  • Works with ABS & Traction Control
  • Fits 2010-2014 GT, GT500 and BOSS Mustangs
Better Launches. This JPC Line Lock system will allow you to "lock up" your front brakes while letting your rear tires spin freely, making for easier burnouts and faster launches.

Saves Wear & Tear. The JPC Line Lock system works with a flip of a switch. When activated, the JPC system uses a solenoid to maintain line pressure to your front brakes only, until the system is deactivated with the flip of a switch. The result is less wear and tear on your Mustang's rear brakes when compared to the traditional left foot braking method, since your brakes don't have to fight your Pony's power to keep spinning.

Complete Kit. This complete kit includes two polished stainless 8mm lines, a rebuildable solenoid, and all necessary fittings, wiring, connectors, and a switch and fuse holder. It is designed for a hassle-free installation, with no line bending required.

Application. The JPC Racing Line Lock Kit is a bolt-on mod for 2010-2014 GT, Shelby GT500 or BOSS 302 Mustangs.

      Hi team, can i use this whit my automatic mustang 2014 GT? thanks

      • The JPC Racing Line Lock Kit is compatible with both automatic and manual Mustangs.

      Where under the hood does the solenoid mount? The lines don't seem to be bent for a mounting next to the master cylinder like other kits.

      • The JPC Racing Line Lock Kit will mount the solenoid on the driver side strut tower, just below the valve cover height.

      Will Russell or J&M stainless lines work with the JPC Line Lock?

      • This has nothing to do with the replacement SS lines you are talking about. This installs under the hood at the "brain" of the system. So yes, any oem or aftermarket lines will work since they have nothing to do with each other.

      Can I still use Russell's SS brake lines?

      • Hi, This JPC Racing Line Lock Kit will work with Russell stainless steel brake lines.

          Nice product but could improve

          A couple of electrical pieces were missing. Lines were pre-bent but both still had to be bent in several places in order to fit. Mounting tab is too long to get two bolts in to secure to frame but one will hold fine. Product works great.

          It works, but...

          It took some extra time as after install the pressure valve was overheating. After trouble shooting I found the included switch was faulty allowing a of voltage to activate the system in the off position. If I had not caught that it would have surely destroyed the valve overnight. You also need to really push hard on the brakes to get it to have its full stopping power... maybe they are all like that... but felt normal brake pressure should have sufficed.

          Good Product

          Item was designed excellent. Works great. Instructions could be a little better, and wiring connects are not of high quality. But those are a dime a dozen to use your own. Overall very pleased with product.

          Smoke and Mirrors

          I purchased this item for my 2011 GT500... The instructions tell you to remove the ABS line from the ABS manifold and nothing more on that particular line.. To Start off you must remove the radiator cover the ram air tube then bend and twist the brake line to get it out from under the rest of the lines on the manifold or you can remove the lines above this one to be remove and it will slip out like it has greasy snot applied. So the OEM line is bent out of factory configuration to remove. The new line to the ABS Manifold is not a plug and play then move to the rear line..It must be bent to fit because it rest against the other brake lines so the fitting will not be close enough to even start the threads so have fun.. It took be from 7 am to 8 pm to complete the install of just the lines and lock solenoid. NEXT... Be cautious of where the instructions tell to to Installing the switch in the console..... Directly behind the area where the instructions shows the switch installed is a plastic support with a wiring harness at the bottom. If you do not use a router bit on a dremel to remove the material the switch will pop out when you try to push the console cover back into place so be prepared to spend time to shape the support to accommodate the switch and be very meticulous about how much you remove to much will cost you a new console.

          Works great

          Installed at home. Trying to get the old line out was a pain, but it came out new lines fit almost perfect. So keep em loose to allow movement. Car is incredibly stable even in a second gear burnout on d/r's.

          JPC linelock

          This product came as a bunch of loose parts with no instructions. I have installed line lock kits before in the past so I do have some knowledge on how they work and installation. The on line instructions on the American Muscle website are for a completely different product not a line lock kit. I texted the American Muscle tech line and the “professional” was unable to provide any help or instructions. His only advice was to take it to a shop. Lol I eventually found the wiring diagram and instructions on the manufacturer’s website. In the end this kit is correctly installed but does not work. It drags on the front brakes but will not hold them when activated. In short I would not buy this kit. I also wouldn’t look to American Muscle for any help.

          So much fun

          Installed easy enough. I don’t use this for racing. The fun factor smoking tires is incredible. Installed with SS brake lines that’s why it took all day. This item probably installed in2/3 hours by itself.

          JPC smoke them if you have them.

          This kit was straight forward and does just what it's supposed to do. Only issue I had was my dioid was wired backwards from JPC. American muscle couldn't diagnose my problem so they had me call JPC direct. JPC told me the had a "batch that were wired backwards". Onece I fixed this issue everything worked perfectly.

          fun button

          I've been testing this since installing the kit last week. It is so much fun! Installation was easy. The most work was running the wiring to where I mounted the switch on my console. Took a little over 2 hours to do the entire install!

          Lock 'em up

          Took about 4 hours to install and then bleed the system. Overall, happy with this kit. Directions were nice but did leave out certain details. Generally I don't do electrical work but the electrical directions made it very easy to figure what wires and circuits to tap.

          Great for warming tires

          JPC line lock kit with pre bent lines fit perfectly. The directions are simple to follow and they come with pictures! The hardest part is bleeding the brakes. I did have to find directions to disassemble the center council for the switch. I had to purchase a momentary switch also.
