Used Truck Alternators – 24V Heavy-Duty Charging

Alternators are at the heart of the charging system on any modern heavy truck. While the starter and batteries get the engine turning, the alternator is what keeps the electrical system powered and the batteries charged during operation. On 24V commercial vehicles it has to support lighting, heating, safety systems, electronics and auxiliary equipment all day long. In this Alternators category you will find tested used OEM truck alternators removed from late-model European vehicles in our UK breaker yard and listed with clear photos and honest descriptions.

What truck alternators we stock

Our stock in the Ignition, Charging & Starting > Alternators category changes as we dismantle more donor trucks, but typical items include:

• 24V heavy-duty alternators for modern Euro 5–Euro 6 tractor units and rigids, designed for high electrical loads on long-haul and distribution work;
• alternators for specific engine families such as Mercedes-Benz OM470/OM471/OM473, Volvo D11/D13, DAF MX series and comparable MAN and Scania engines;
• BOSCH, Valeo and other OEM-brand alternators supplied on Volvo, MAN, DAF, Scania and Mercedes trucks from the factory;
• alternators with different amp ratings, pulley types and mounting configurations to suit various applications and bodywork specifications;
• other alternator variants taken from our donor trucks as part of complete charging and starting systems.

Each listing shows the actual alternator you will receive, with close-up photos of the label, plug connections, mounting ears and pulley, together with any visible OEM part numbers. This makes it easier to compare the unit directly with the alternator fitted to your truck before ordering.

Truck brands & typical applications

Most of the alternators we supply come from mainstream European heavy trucks such as Volvo FH/FM, MAN TGX/TGS, DAF CF/XF, Scania R/S and Mercedes-Benz Actros, Antos and Arocs. VRA Truckparts is a UK-based specialist in used OEM truck parts, dismantling carefully selected Euro 5–Euro 6 donor vehicles at our yard in Stanford-le-Hope, Essex and supplying components to fleets, workshops and owner-drivers across the UK and EU.

Typical applications include replacing a failed alternator on a high-mileage tractor unit, upgrading to a higher-output unit for trucks with additional electrical equipment, or fitting a correct OEM-spec alternator after repeated issues with non-genuine replacements. Using a genuine used OEM alternator helps maintain the proper output, mounting and plug configuration for your engine and wiring harness.

Tested used OEM alternators from dismantled trucks

Before any alternator is added to stock, it is removed carefully during our structured dismantling process. Units are visually inspected for housing damage, cracked mounts, seized pulleys and signs of overheating. Where possible we assess operation on the donor vehicle or with basic tests before removal. Alternators that clearly do not meet our standards are set aside rather than listed for sale.

Because all alternators come directly from trucks we dismantle ourselves, we can usually provide donor information such as make, model, engine type and Euro class, along with OEM part numbers and reference codes shown in the photos. This transparency helps workshops and fleet operators match the correct alternator to their vehicle and avoid compatibility issues.

Shipping, returns and checking compatibility

Truck alternators are robust but heavy electrical components, so we pack them securely to protect pulleys, housings and connectors in transit. Orders are dispatched quickly from our Essex yard with tracked delivery options across the UK and EU, and most parts include a 30-day returns period so you can fit and test them on the vehicle with confidence.

If you are unsure whether a particular alternator will fit your truck, contact VRA Truckparts with your registration, VIN and clear photos or part numbers from your existing unit. Our team will help you confirm voltage, output rating, mounting pattern and plug type, or suggest suitable alternatives within the Alternators range. You can also browse the main Ignition, Charging & Starting category and related sections like Starters and Batteries to source complementary parts for the rest of your starting and charging system.
