Line Locks

Line Locks & Brake Line Lock Kits

Line locks are solenoid valves that lock hydraulic pressure to the front brakes while releasing the rear brakes, allowing burnouts and tire warming without applying the parking brake. Line locks are essential for drag racing launches and are required by many sanctioning bodies for bracket and heads-up racing.

OneFastShop carries line locks including electric line lock solenoid kits, line lock switch and wiring kits, roll control kits, and direct-fit and universal line lock installations for drag racing, muscle car, and performance builds.

Every line lock at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're heating the tires before a pass, building a dedicated drag car, or adding roll control to a street/strip vehicle, OneFastShop has the line lock. Shop the full line locks collection today.
