RacePro RPM Engine Speed Limiter RL2 for 4-Cylinder Engines
The RacePro RL2 is an electronic engine speed limiter for four-cylinder applications. It is used to control the engine’s upper RPM range when a defined maximum speed is required. Designed for 4-cylinder engine applications. The limiter is an engine-control component rather than a carburetor metering part, so it does not alter main-circuit fueling, progression, emulsion, enrichment, or fuel-level control.
Correct integration depends on the engine’s ignition or control-system architecture and the available wiring interface. An incorrectly matched or connected limiter can cause unwanted RPM intervention or prevent the control function from operating correctly. Confirm the required installation method and system compatibility before connecting the RL2.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: RL2.
