Sierra Rotor 18-5430 for Chrysler Marine 6-Cylinder HCS, LHS Engines (Replaces Chrysler Inboard 868095)

The Sierra Rotor 18-5430 is a distributor rotor engineered for Chrysler Marine 6-cylinder inboard engines, including the HCS and LHS models. As part of the distributor cap and rotor assembly, the rotor rotates inside the distributor cap and directs high-voltage current from the ignition coil to the correct spark plug terminal in firing order, making it a core component of a proper ignition tune-up. Replacing a worn, cracked, or burned rotor restores consistent spark distribution, which helps prevent misfires, hard starting, and rough idle caused by a deteriorated ignition contact.

This rotor is manufactured to fit the same mounting and contact specifications as the original Chrysler Marine equipment, allowing for straightforward installation as part of a routine tune-up or ignition system service. It is commonly replaced alongside the distributor cap, points, and condenser on 6-cylinder HCS and LHS Chrysler Marine inboard engines. The Sierra Rotor 18-5430 carries the Sierra brand's part number 18-5430 and cross-references to Chrysler Inboard part number 868095.
