SLP Line Lock Kit for all 2011-2012 V6, GT and GT500 Mustangs.
A true SLP exclusive, their line lock kit was developed and designed to fit 2011-2012 V6, GT and GT500 Mustangs as a "true bolt-on" package. This kit is custom fitted for the Mustang chassis and is fully compatible with the factory anti-lock braking and traction-control systems. No custom fabrication, no wire harness nightmare and no trips to the hardware store, no other kit offers this ease of installation and convenience period!
Here's how it works; press the brake pedal and flip the brake-control solenoid switch. Remove your foot from the pedal and the solenoid maintains line pressure to the front brakes until the switch is released. This makes it easy to heat the rear tires while minimizing wear and tear on your car's rear brake components. You can also use the system to prevent a manual-trans car from rolling out of the staging beams at the starting line.
