6800 RPM Module

The 6800 RPM Module from MSD Ignition is a precision ignition control component designed for high-performance engine builders and experienced mechanics seeking reliable rev limiting and spark timing management. This compact unit addresses a critical need in modified engines: preventing over-rpm damage while maintaining ignition integrity across demanding driving conditions. Whether you're tuning a street machine, bracket racer, or high-output build, the 6800 RPM Module provides the electronic foundation needed to safely push engine performance without risking catastrophic failure from unchecked RPM climb.

This module functions as an RPM limiter that electronically controls ignition output to prevent engine speed from exceeding your preset 6800 RPM threshold, a common safety ceiling for naturally aspirated street engines and many forced-induction platforms. MSD Ignition's engineering ensures the module integrates seamlessly with existing MSD ignition systems and aftermarket distributors, providing repeatable, precise rev limiting without the mechanical complexity of traditional governor systems. The ultra-compact design—measuring just 1.7 x 0.45 x 2.75 inches—allows discreet mounting in tight engine bays, while robust circuitry withstands heat cycling and electrical stress common in modified vehicles.

Technicians and engine builders favor the 6800 RPM Module for applications ranging from small-block Chevys and Ford Windsor platforms to various import turbocharged engines. Its versatility makes it an essential tool for those looking to enhance performance while ensuring engine safety. With its reliable electronic rev limiting capabilities, this module is ideal for anyone looking to push their engine's limits without compromising on performance or safety.
