Drag Specialties 2112-1062 Black Premium Solid-State Voltage Regulator for Harley-Davidson Big Twin

The Drag Specialties 2112-1062 is a premium solid-state voltage regulator engineered as a high-performance replacement for Harley-Davidson Big Twin motorcycles from 1989–1999. Designed to replace OEM part 74519-88, this unit delivers reliable, consistent charging system performance for Evo-era Big Twin models.

Two years of engineering development went into this premium regulator design. Fully assembled in the U.S.A. with domestically produced electrical boards, each unit is tested three separate times during the assembly process to ensure quality and reliability before it leaves the factory.

Key Features:

• Premium solid-state design — no relay contacts to wear out or fall out of adjustment over time
• All-aluminum die-cast housing in a sleek black finish for a clean, stock-style appearance
• Superior internal heat management for more reliable performance under sustained electrical loads
• Environmentally sealed for protection against moisture and vibration
• Accurately regulated 12V output under all electrical load conditions
• Made in the U.S.A. with domestic electrical components
• Replaces OEM part number 74519-88

This black-finish voltage regulator is the ideal upgrade for any Big Twin owner experiencing charging issues or looking to replace an aging OEM unit with a more durable, precisely engineered aftermarket solution.
