What is a line lock on a car? Also called anti-roll systems, launch controllers, or staging locks, line locks are crucial components for drag racers. Once activated, they lock up your front brakes independently of the rear brakes, so you’re ready to perform a tire-smoking burnout, or remain staged until the lights turn green.

TCI Electric Brake Line Locks

In dirt track racing the drivers take all left turns. When braking is needed going into the turn, you need a way to stop the straight push that regular brakes give. TCI electric brake shut-offs essentially disengage the right front caliper, allowing it to free-wheel when brakes are applied. These continuous-duty solenoids are made from lightweight 6061-T6 aluminum and can be mounted anywhere between the master cylinder and caliper. Just hit the switch before braking and the solenoid shuts off the fluid going to the right brake before pressure is built. When you want both front brakes to work, just hit the switch again. The brake line locks feature a waterproof seal and the ability to handle up to 3,000 psi; they use only 1 amp of current, and work with all hydraulic brake systems. TCI electric brake shut-offs enhance corner entry braking, allowing for smooth transitions throughout the race.
