Starters and alternators. For a good start.

Knorr-Bremse TruckServices offers high-quality solutions for commercial vehicles. You can rely on our starters and alternators – right from the start.

Team player

Nothing runs without a starter! But not even a starter can run without an alternator! Both of these components have to work – with no ifs, ands, or buts. They have to function at all times, even in difficult road and weather conditions, or in extreme cold and heat. If the alternator or starter fails due to heavy loads, the vehicle will no longer run. Such issues should be avoided at all costs – every standstill costs money. Prevent them by replacing components promptly. With a broad portfolio of starters and alternators, Knorr-Bremse TruckServices offers solutions for commercial vehicles from every major manufacturer in OEM quality. They are robust, long-lasting and compact.

Starters – Brilliant cold start performance

Combustion engines, which are currently the leading drive technology in commercial vehicles, don’t start on their own. They cannot function without a starter. The starter accelerates the engine to get it running. It gets the current it needs to do so (for this short, yet high-energy consumption moment) from the battery. The expectations are high: Starters can be impacted by vibrations, dirt and even penetration of water. Replace the starter before it stops working due to wear and tear. Starters from Knorr-Bremse TruckServices are reliable replacement parts tested under extreme conditions. In particular, they provide outstanding cold start performance.

Alternators – extreme heat resistance

The alternator is the energy source for commercial vehicles. It converts the mechanical energy from the running engine into electrical energy. This supplies all devices in the vehicle, as well as the battery, with current. The starter will not work with an empty battery. Because of this, the alternator has to be able to run reliably at all times. A reduction in the alternator's power due to wear can cause a vehicle standstill. Be proactive: with a replacement part solution from TruckServices that matches the needs of your vehicle. Our replacement parts are equivalent to original parts in terms of their quality and function: they are resistant, tested, and extremely heat-resistant.
