Anyone who owns a car with rear-wheel drive or a disengageable all-wheel drive and wants to spin the rear wheels during races can make the process easier with the so-called LINE LOCK function. The "Line Lock Module" is a component that is already in the Drag Race Scene is known. In order to let the rear wheels spin without the car moving, the front wheels must of course stand still. Various tuning workshops are taking on the challenge of installation by retrofitting the Line Lock function. By the way, the Dodge Challenger Redeye and also the Demon have already installed this function ex works. Line Lock is discussed in more detail below.
Line Lock - known in drag racing
Tuned cars that are used in drag racing, for example, require professional and flawless tuning equipment. It is not uncommon for cars with more than 1000 hp to be used in the drag race. A car with rear-wheel drive and line lock function can be used perfectly to spin the rear wheels. This attracts attention and focuses on the driver during the drag race. Of course, the point is to bring the rear wheels to the right temperature. The Line Lock function integrated in the car ensures that the front wheels are consistently stationary while the driver spins the rear wheels. These spin until the brake is released or the tire blesses the time.
Line Lock - brake pressure is on the front axle
A drag race driver heats up the rear wheels before the actual race. The tires are a so-called Burnout exposed. The driver of the car applies the brakes and the integrated line lock (must be activated) ensures that the brake pressure is only distributed to the front axle. The rear brakes are virtually disconnected and the rear wheels do not lock. So there is a spin of the rear wheels that enables a perfect burnout without much effort. As already mentioned, the Line Lock is only intended for cars with rear-wheel drive or for those that have an all-wheel drive, the function of which can be deactivated on the front wheels. And the function should only be used when a drag race or another permitted racing event is taking place. So please don't at the traffic lights or in front of the ice cream parlor!
Line Lock software regulates brake pressure
The line lock is certainly not seen as a useful function by outsiders. The layman thinks it should only be fun and make the hearts of racing enthusiasts beat faster. But that's not true! The function is clearly intended to be able to optimally heat up the rear wheels in an acceleration race without great effort. But it is also a fact that it is not about safety, use and necessity in road traffic. How the system actually works can be seen in many videos on the Internet. Basically it's just some electrical equipment and a control valve for the brake system. The effort is manageable. The manufacturers of retrofit kits point out that the use of such software or the burnout of the rear tires can lead to a limitation of the manufacturer's guarantee. This should of course be considered if the system is to be installed in a "normal" road vehicle. If you want to use the technology of the Line Lock function, you are at the right place at tuning workshops. The employees, especially in the drag racing area, are familiar with the use of the Line Lock function and the possibility of retrofitting and can also explain the legal situation in more detail.
Line Lock - conclusion: The Line Lock function ensures that the brake pressure is distributed to the front axle and the front wheels stand still while the rear wheels can spin. Such a system is used in drag races and makes sense. We hope that the info report on the topic / term Line lock function (further names / keywords: brake line lock, brake control valve, brake valve, burnout function, line lock module) from the field of autotuning.
