Line lock kits are a type of braking system modification that allows a driver to lock the front brakes of their vehicle. This is commonly used in drag racing to hold the car stationary during the burnout process, allowing the driver to warm up the rear tires without the car rolling forward. A line lock kit works by installing a solenoid or valve in the brake lines that can be electronically activated, effectively holding pressure to the front brakes while releasing the rear brakes. This gives a driver more control over their vehicle during a burnout and can help to achieve a better launch off the starting line.
These kits typically include a solenoid valve, wiring, switches, and the necessary fittings for installation. While primarily used for performance applications, some enthusiasts also install a line lock on their vehicle for security purposes, as it can be used to prevent the vehicle from being driven. Whether for the track or for a specific security need, a line lock kit provides a reliable way to control your vehicle's braking system.
