What’s Included:

• (1) Starter Solenoid — Briggs & Stratton 5410K

Fitment:
This OEM 4-post starter solenoid is commonly used on Briggs & Stratton-powered equipment, but is also found on a wide range of machines from other equipment manufacturers that utilize compatible electrical systems.

Common applications include:

• Riding mowers
• Lawn tractors
• Garden tractors
• Other outdoor power equipment

Important Fitment Note:
Starter solenoids are not determined by the engine alone. 3-post vs. 4-post configurations depend on the equipment manufacturer and wiring setup, not just the engine model. Many different brands may use this solenoid style. Always confirm that your existing solenoid has a 4-post configuration and matches your wiring layout before ordering.

Why this matters:

A failing starter solenoid is one of the most common causes of:

• Engine won’t crank
• Clicking sound when turning the key
• Intermittent starting issues
• No power to starter motor

Replacing a faulty solenoid restores proper electrical flow to the starter, helping your engine start quickly and reliably.
