Starters

From off highway heavy equipment to long haul trucks to school bus and transit applications, Delco Remy starters are designed to crank in even the toughest applications.  Our Integrated Over Crank Protection (IOCP), a built-in circuit breaker, protects the starter from thermal damage, automatically resetting at a safe operating temperature while eliminating the need for a wiring harness.
