The JPC S550 line lock kit is now available from JPCRACING! This kit is the only line lock kit available for the 2015+ Ford Mustang.

Many of our customers know that the factory line lock kit is fairly clumsy to use, you have a lot of screens to go through and can be difficult to setup in a rush. With our new line lock kit you can bypass all of the screen and enable the line lock in an instant! This kit also allows you to install a line lock on a car that did not come with the factory option.

This line lock kit also includes stainless steel brake lines for both of the front brakes. Allowing for a firmer pedal and more braking power.

    This is an excellent kit! It contained everything I needed to do a nice clean install and is very easy/straightforward to install. I would definitely recommend this to anyone who races their car a lot. My Ecoboost didn't have a factory linelock option, but JPC has provided an excellent solution! It also solves another issue I had. My transbrake is activated by my brake pedal. So when doing my burnout, I had to disable the transbrake in my tune then re-enable it to launch the car. This is no longer an issue thanks the linelock kit!
