WAI 17803N Starter Solenoid Plunger Replacement Component

The WAI 17803N is a 100% new starter solenoid plunger designed as a precision-fit replacement component for compatible starter assemblies. As a key internal part of the starter solenoid, the plunger is responsible for converting the solenoid's electromagnetic energy into mechanical movement, engaging the pinion gear with the flywheel to crank the engine.

Key Features:

• 100% new construction — not remanufactured or rebuilt
• Engineered to meet or exceed OEM specifications for proper fit and function
• Restores reliable solenoid actuation and starter engagement
• Manufactured by WAI, a trusted aftermarket supplier to automotive, heavy-duty, and powersports markets
• Cost-effective alternative to replacing the entire starter assembly

Over time, starter solenoid plungers can wear, pit, or corrode, leading to intermittent starting, grinding noises, or complete no-start conditions. Replacing the plunger restores full solenoid travel and ensures consistent high-current contact closure every time the ignition is turned. WAI part number 17803N is the manufacturer's direct reference for this component.
