PQY Front Brake Line Lock Kit — Heavy-Duty Black 12–24V Solenoid for Roll Control & Hill Holds

This compact kit from PQY delivers a reliable electrical line-lock solution designed for 12–24V systems. Built to withstand pressure spikes up to 1000 psi, the kit provides an easy-to-install, direct-replacement line-lock valve, a reinforced push-button switch, and all wiring and mounting hardware needed to quickly lock front brakes while allowing rear brakes to release during launches or burnouts.

How does the PQY line lock help at the starting line?

The unit holds hydraulic pressure on the front brakes so rear wheels can break traction for burnouts without the vehicle creeping forward. That improves consistent launches and warms rear tires faster with less effort.

• Locks front brake pressure electrically for steady hill/launch holds
• Handles sudden pressure spikes up to 1000 psi for durability
• Works with 12–24V systems — fits common automotive electrical setups

What components and wiring come with the kit?

PQY supplies a rebuildable line-lock valve, a heavy-duty push-button switch with bracket, coiled wiring, a fuse holder and an indicator light so you can mount and wire the system immediately.

• Rebuildable solenoid valve for long-term serviceability
• Coiled wire and fuse holder for neat, protected installation
• Indicator light and switch bracket included for user feedback and secure mounting

Is this unit easy to install and maintain?

Yes — PQY designed the valve as a direct replacement with OEM-standard fitment and obvious wiring points. Routine maintenance is simplified by the rebuildable valve design.

• Direct-replacement form factor for straightforward swap-ins
• Clear wiring and mounting hardware for quick plumbing and electrical hookup
• Rebuildable valve reduces replacement costs over time

What safety and usage considerations should I know?

The device is intended to assist with controlled launches and burnouts; it does not replace brake system repairs or safety inspections. Use on closed courses or legal racing venues and follow local regulations when modifying brake controls.

• Designed for use with properly maintained brake systems only
• Not a substitute for functional brake components or professional installation if unsure
• Intended for motorsport and performance use — check local laws for street use

Who is this for? Drivers and mechanics who want a dependable, serviceable line-lock solution for drag racing starts, hill holds or controlled burnouts will benefit from the PQY kit. It suits performance enthusiasts retrofitting street cars, racers building a reliable launch system, and shops that prefer a rebuildable valve and complete mounting hardware for fast installs.
