Description
Don’t let a “Quick Start” become a “Dead Stop.”
We’ve all been there: the adrenaline is pumping, the grid is calling, and you’re ready to pull the cord. But if you forgot the oil, that first roar is the last sound your engine will ever make.
Introducing the Seize-Stopper, your engine’s ultimate insurance policy. This high-visibility, 3D-printed safety lockout sits directly on your spark plug, physically preventing you from connecting the plug wire until you’ve confirmed the oil level.
Why you need it:
Visual Warning: Features a bright “STOP – NO OIL” sign that is impossible to ignore.
Physical Lockout: Prevents the spark plug boot from seating, making it physically impossible to start the motor.
Paddock Proof: Designed for the rugged environment of the pits—durable, lightweight, and easy to toss in your tool kit.
Universal Fit: Designed to fit standard karting spark plugs (NGK, etc.).
Protect your investment. If the sign is on, the oil is gone.
