Tire Fryer Line Lock Kits are used for drag racing to lock the front tires of the car. This decreases the chance of your car rolling through the lights before it's time. Also locking the front wheels produces a more efficient burn-out to heat up your tires. Extensive testing has shown a 10-millisecond release time with vibration resistance up to 30-G's with no mechanical failure. On the street or off-road, the GMS Tire Fryer can also be used as a temporary electronic parking brake when both the clutch and brake are needed at the same time. Includes a re-buildable nickel-plated solenoid valve, activation switch (shifter mountable), arming light, stainless steel inserts, and black chromate heat sinks.
