Line Lock Kit, 1998-02 Camaro/Firebird, shipping is not included An SLP exclusive, this unit is designed to fit all 1998-2002 V8- and V6-powered GM F-Bodies. 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. This kit is custom-fitted to the F-Body chassis and is fully compatible with the factory anti-lock braking and traction-control systems. It includes a waterproof electrical solenoid, an activation switch, plug-in wires, CNC-bent steel lines with correct OE fittings, mounting hardware, and detailed installation instructions.
