BBB Industries 11457 Alternator

Reman Alternator for Sprinter Charging Systems

BBB Industries REMAN ALTERNATOR 11457 is a 12-volt, 220-amp replacement alternator built for Mercedes-Benz Sprinter and Dodge Sprinter applications. It uses an internal voltage regulator, clockwise rotation, and a clutch-style pulley to match the charging system requirements of listed vehicles.

This remanufactured alternator is a direct-fit option for 2019-2021 Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD, plus earlier 2009-2018 Sprinter applications where equipped. Part number 11457 is also cross-referenced to Valeo-style OE numbers for the same application.

Key Features

• 220-amp amperage rating for high-output charging demand
• 12-volt electrical system with internal voltage regulator
• Clutch pulley with decoupled pulley design
• 7-groove serpentine pulley included
• Air-cooled housing with internal fan
• Negative polarity and clockwise rotation
• OE manufacturer reference: Valeo
• Plug clock position: 3

Product Details

BBB Industries REMAN ALTERNATOR 11457 is engineered around the OE-style configuration used on Mercedes-Benz Sprinter and Dodge Sprinter charging systems. The unit features a 2-inch pulley diameter, serpentine belt drive, and internal regulator layout to support proper electrical output in vehicles that rely on a high-capacity alternator. The clutch pulley design helps manage belt dynamics under changing engine speeds, while the air-cooled, internally fan-cooled construction supports thermal control during operation.
