JEGS 555-405221 SSR-III Ready-to-Run (RTR) Pro-Series Distributors

The SSR-III RTR Pro Series Distributor is engineered for maximum ignition performance with a 7.5-amp rated dwell control circuit, delivering 400 volts and 125mJ of spark energy to the coil, while generating 46,000 volts from the coil to the plug for powerful and consistent spark delivery. Designed for precision and reliability, it features a single-stage rev limiter, which is easily set by grounding the tachometer lead at half the desired engine speed. The tach lead outputs a 25% duty cycle square wave signal, ensuring compatibility with multifunction tachometers and most aftermarket EFI systems. For improved hot restarts and reduced strain on the electrical system, a fully automatic start retard provides 4 degrees of timing retard during cranking, which is fully dialed out by 300 RPM. Built for durability, the digital inductive control module includes reverse polarity protection, while the isolated grounding system ensures a stable ground connection even if the distributor body isn’t in direct contact with the engine block or intake manifold. With its high-output performance and advanced features, the SSR-III RTR Pro Series Distributor delivers exceptional ignition control, making it the perfect choice for demanding applications.

JEGS 555-405221 SSR-III Ready-to-Run (RTR) Pro-Series Distributor Notes:

• Requires use of CD (Capacity Discharge) Ignition Coil, we recommend 555-40155, 555-40150, 555-40118 and 555-40119 sold separately
• The Built-In Rev Limiter is Turned Off from the Factory
  • Rev Limiter is ONLY for use on Carbureted Engines
  • Rev Limiter is NOT Compatible and MUST be Left Off on Fuel Injected (EFI) Engines
  • Setting and Adjustment of the Rev Limiter Requires the use of a "Square Wave Signal" Compatible Tachometer such as JEGS 555-41262 or equivalent (sold separately)
• The Start Retard Function is Preset @ 4 Degrees of Retard, Fully Automatic, and Requires NO Input or Programming
• Will not fit post-1985 High Output 5.0L engines because of the included iron gear; typically, 5.0L engines require a steel gear and lack of EFI/TFI compatibility
