Rely on tested quality and order your starter system online.

Energy from the very first moment

The starting system ensures that your engine is brought to life with components such as the starter, magnetic switch or drive elements. Without the starter system working, no vehicle can get moving, which is why it plays an essential role in the drive system.

Precise technology for a smooth start-up

Each individual part – whether armature, freewheel, ring gear or magnetic switch – must fit exactly in terms of dimensions, connection geometry and load. This is the only way to ensure a reliable connection between the battery, control unit and motor.

Starting system

What should you look out for when buying:

TENSION

Make sure that the components match your vehicle electrical system voltage (e.g. 12 V, 24 V) and the required starting power.

MODEL AND ENGINE

Make sure that parts such as the ring gear, drive or magnetic switch are compatible with your vehicle and engine model.

MECHANICAL COUPLING

Check that the connection thread, mounting flanges and mechanical connecting parts are precisely matched to each other so that the starting operation functions properly.

Expert Guide: Everything You Need to Know About the Launch System

The starting system causes the engine to start. With components such as the starter motor, solenoid, and drive elements, it provides the engine with the necessary initial rotation. Without a functioning starting system, no vehicle can move—it therefore plays an essential role in the powertrain.

The starting system includes, among other components, the starter motor with its armature, the solenoid, the freewheel (pinion), and the ring gear. The solenoid pushes the pinion into the ring gear and engages the main circuit, while the starter motor generates the rotational motion that starts the engine.

The solenoid switch performs two functions: It engages the starter pinion with the ring gear and simultaneously supplies the high starting current. If it does not function reliably, the engine will not start or will start only intermittently—it is therefore a key component of the starting system.

Typical signs include a starter motor that only clicks without turning, an engine that won’t start at all or starts only after a delay, a starter motor that spins freely without engaging the engine, and grinding noises during startup. Common causes include worn armatures, freewheels, or a faulty solenoid switch.

The components must be compatible with the vehicle’s electrical system voltage (e.g., 12 V or 24 V) and the required starting power. Make sure that parts such as the ring gear, drive unit, or solenoid switch are compatible with your vehicle and engine model, and that the connection threads, mounting flanges, and connecting parts are precisely matched.
