At Truckstop, our collection includes starter motors, alternator belts, and alternators for a wide range of vehicles, giving you confidence in every journey.

The starter motor is responsible for turning the engine over and initiating combustion. A failing starter can leave a truck stranded, making quality and reliability essential. Our starter motors are designed to deliver consistent torque and withstand the demands of heavy‑duty use.

Alternators generate electricity to recharge the battery and power the vehicle’s electrical systems. An alternator must provide steady output under varying loads, from lighting and HVAC systems to safety equipment and auxiliary devices. Our alternators are built to deliver consistent performance, ensuring that batteries remain charged and electrical systems operate without interruption.

Alternator belts transfer mechanical energy from the engine to the alternator. Worn or damaged belts can cause charging failures, leading to battery drain and electrical faults. 

Truckstop’s starters and alternators are sourced from the leading manufacturers, so every component meets industry standards. Whether you need a Scania alternator, a DAF starter motor, or a replacement alternator belt, Truckstop provides the solutions you need to keep your trucks on the road.

Frequently Asked Questions

What are the signs of a failing starter motor?

Difficulty starting the engine, clicking noises without turnover, or complete failure to crank are common indicators of a worn starter motor.

How often should alternator belts be replaced?

Alternator belts should be inspected regularly and replaced if worn, cracked, or showing signs of fraying. Many operators replace belts every 50,000 to 80,000 miles as part of routine maintenance.
