Now Available: The New Prestolite Line

Every reliable vehicle depends on a high-performance charging and starting system. When either one fails, the vehicle stops running.

Prestolite alternators and starter motors are engineered to deliver dependable starts, stable electrical power, and long service life in demanding applications. Now stocks the full range across the Americas — backed by nearly three decades of supply experience and direct access to our product specialists.

From distributors and fleet operators across the Americas, we specify Prestolite through Leader Autoparts.

Alternators: Supplies electrical power while keeping the battery charged, ensuring reliable operation of lighting, electronics, and other essential vehicle systems. Consistent output under load means fewer no-start callbacks and less time off the road.

Starters: Delivers the torque needed for quick, reliable engine starts while reducing downtime and supporting dependable daily operation. Built to hold up through repeated cold starts and heavy-duty duty cycles.

Why The Prestolite Line: (1) OEM-grade manufacturing — Components built to original equipment specification, not a second-cost equivalent. (2) Broad application coverage — Millions of vehicles across passenger cars, light and medium commercial vehicles. (3) Dependable supply — Stocked and shipped across the Americas, so orders don't sit on a container. (4) Direct technical support — When compliance reps and field teams want questions answered, our product specialists are standing by. (5) Built for service life — Engineered for high-demand, high-cycle operation rather than shelf appeal.

A starter and an alternator only get noticed when they fail. Our job is to make sure they never become the reason a vehicle sits.
