Distributor Lock-Out Kit

The Pertronix Ignition Distributor Lock-Out Kit (model D9010) is a precision ignition component designed for users who need to lock out spark advance in high-performance or specialty engine applications. This aluminum lock-out mechanism prevents unwanted distributor advance during initial startup, tuning, or specific racing conditions where fixed ignition timing is critical. Fabricated from durable aluminum in a natural finish, this kit serves engine builders, hot rodders, and performance technicians who demand precise control over ignition timing parameters.

Built to work with Pertronix Flamethrower distributors, the lock-out kit functions by mechanically restricting the advance mechanism, ensuring timing remains fixed at a preset value. The aluminum construction provides both lightweight design and excellent corrosion resistance, while the compact footprint—measuring 2.05 x 2 x 3.35 inches and weighing just 0.04 lbs—allows for seamless integration into tight engine bays. This design eliminates variable advance during critical engine operation phases, giving tuners the stability needed for repeatability and safety testing.

Technicians and builders benefit most from this lock-out kit when diagnosing ignition issues, establishing baseline timing before dynamic advance tuning, or running fixed-timing configurations in racing environments. Its compatibility with Pertronix Flamethrower distributors makes it an essential upgrade for anyone standardizing on this ignition platform. Installation requires no special tools, and the aluminum natural finish resists weathering—ideal for workshop environments or under-hood mounting where reliability and durability are non-negotiable.
