About This Product

Keeping your electrical connections clean and dry is vital for long-term reliability, and this black rubber solenoid boot from MCS is the perfect solution. Designed as an OEM-style replacement for part 31441-65A, it provides a snug, protective seal over the starter solenoid terminals. This boot fits a wide range of Harley-Davidson motorcycles, including 1965 to 1988 Big Twin models and 1967 to 1980 XL Sportsters. Over time, original rubber boots can perish, crack, or go missing, leaving your solenoid exposed to road grime and moisture. Installing this fresh replacement ensures your starter system stays protected from the elements, preventing corrosion and potential shorts. It is a simple but necessary part for any proper service or restoration.

Manufacturer part number: 904570.
