PQY Front Brake Line Lock Kit — Red Heavy-Duty Solenoid, Rebuildable 12–24V Roll Control

This compact kit gives drivers reliable on-demand front brake retention without altering the factory hydraulic system. Designed for 12–24V electrical setups, the assembly tolerates pressure spikes up to 1000 psi and installs as a direct replacement for many line-lock units. Whether you need a controlled burnout, cleaner launches, or to hold the vehicle on an incline, this kit provides a clean, serviceable solution with a visible indicator and robust hardware.

How does this kit help with launches and burnouts?

By trapping hydraulic pressure at the front brakes, the solenoid lets you hold the car stationary while spinning the rear wheels. That makes staged launches and controlled burnouts simpler and more repeatable. The valve is rebuildable, so you can maintain consistent operation track after track.

• Locks front brake pressure for secure hill holds and drag starts
• Allows rear-wheel spin without vehicle creep
• Rebuildable line-lock valve for long-term reliability
• Handles pressure spikes up to 1000 psi

What comes in the box and how easy is installation?

The kit ships with everything needed for a straightforward install: the line-lock valve, a heavy-duty push-button switch with bracket, coiled wiring, a fuse holder and an indicator light. The electrical side ties into 12–24V systems and the valve replaces many existing units with minimal modifications. Basic mechanical and electrical skills are recommended for safe, clean routing and mounting.

• Rebuildable solenoid line-lock valve included
• Push-button switch, mounting bracket, and coiled wire
• Fuse holder and indicator light for visible status
• Direct-replacement design for quick swap-in fitment

Will this work with my car’s electrical and brake system?

The device is compatible with standard 12–24 volt automotive electrical systems and integrates with hydraulic brake lines using common plumbing fittings. It’s built to withstand racing-level pressure events but should be installed in accordance with vehicle manufacturer and motorsport guidelines. If your car has ABS or complex electronic brake control, consult a technician before fitting.

• Works on 12–24V vehicle electrical systems
• Suitable for most hydraulic brake lines and drag applications
• Pressure-rated for demanding start-line use
• Professional installation advised for ABS-equipped vehicles

Who is this for? Drivers who want a dependable, serviceable line-lock for drag racing, staged launches, or hill-hold tasks will find this PQY kit well suited to their needs. It’s aimed at motorsport enthusiasts, weekend racers, and anyone performing burnouts or requiring temporary front-brake retention. If you need a straightforward, rebuildable unit with visible status indication and heavy-duty components, this kit is built to perform without unnecessary complexity.
