Biondo Racing Brake Hydraulic Line Lock Kit

Biondo Racing & Brake Hydraulic Line Lock Kits: Built on the Track, Proven at the Strip

When it comes to drag racing staging hardware, few names carry the credibility that Biondo Racing Products has earned over decades of competition. The Biondo family philosophy — "Products for Racers by Racers" — is not just a tagline. It traces back to Sam Biondo's very first race in 1958, and every product the company engineers reflects the hard-won knowledge of a family that has turned thousands of competitive laps on strips across the country.

Within the world of brake hydraulic line lock kits, Biondo Racing occupies a respected niche. A line lock, at its core, is an electrically actuated solenoid valve that traps hydraulic pressure in the front brake circuit, holding the front wheels locked while freeing the rear wheels to spin. This lets drivers execute a controlled burnout to heat their slicks, or hold the car staged at the starting line without riding the brake pedal — both critical rituals in competitive drag racing.

What Sets the Biondo Line Lock Apart

Biondo's line lock solenoid (part number LL) is the flagship product in this category, and it earns its reputation through a combination of thoughtful engineering details that matter to working racers:

• Waterproof coils — engineered to survive the hostile, moisture-rich environment of the water box and outdoor strip conditions.
• High-flow ports with 1/8 in. NPT female threads rated at an impressive 3,000 psi, providing reliable hydraulic holding power even under heavy throttle application.
• Built-in mounting tabs that make installation straightforward and secure, minimizing cockpit fabrication time.
• Rebuildable construction — unlike many competitors' sealed units, Biondo's line lock is designed to be serviced and rebuilt, delivering years of reliable performance rather than being thrown away at the first sign of wear.

For racers who want the complete wiring solution, Biondo also offers the LLK Linelock Accessory Kit, which includes a heavy-duty pushbutton activation switch, an indicator light, an inline fuse holder, and fuse — everything needed to wire the solenoid into the vehicle's electrical system cleanly and safely.

Race-Tested Confidence in Every Kit

Biondo Racing was officially opened as a company in 1987, but its product ideas have always been born on the track and refined in response to real-world racing demands. The line lock is a perfect example: it reflects exactly what a racer needs at the starting line — unsurpassed holding power, durable materials, and a design that keeps working race after race. Whether you're a bracket racer looking to nail consistent 60-foot times or a class racer who needs every staging advantage available, Biondo's line lock kit is a proven tool for the job.
