Long Haul® School Bus

Bosch Long Haul School Bus Alternators 

Bosch 200 AMP Long Haul® School Bus alternators provide higher amperage output at engine idle than competitive brands. Bosch is fast becoming recognized as the industry leader and OE supplier to the school bus market.

Long Haul® School Bus alternators for school buses, special applications, and RVs provide the following benefits:

High Temperature Resistance
The Bosch Long Haul Alternators can really take the heat! At operating temperatures of up to 125°C (257°F), the Bosch AL9962SB and AL9963SB sustains operating amperage better than competitive units to supply more power for critical electrical systems.

Regulator Self-Protection
At 125°C the Bosch self-protection feature reduces output of the alternator temporarily. Output goes back to normal after the extreme temperature subsides. This feature protects the alternator from any permanent damage.

2-Year Warranty
Because of the Long Life Design, Bosch backs the AL9962SB and AL9963SB with a 24 month/200,000 mile warranty.
