Who is behind SLP (Swedish Lorry Parts)?

Anyone looking for spare parts for Volvo Penta, Scania Marine, or heavy diesel engines will often find parts from SLP. The abbreviation stands for Swedish Lorry Parts. The company is based in Sweden and specializes in spare parts for heavy commercial vehicles, construction machinery, industrial, and marine engines.

The headquarters of Swedish Lorry Parts AB is located in Norsborg, southwest of Stockholm. The official address is Fågelviksvägen 9, 145 53 Norsborg, Sweden. Additionally, SLP operates a central warehouse in Kumla. This warehouse is conveniently located in central Sweden and, according to the company, is designed for fast international deliveries.

SLP was established in the early 1990s. Swedish Lorry Parts AB has been registered in Swedish company registers since 1990, while SLP itself states 1991 as its founding year. According to current published figures, the company employs 57 people and generated sales of approximately 260 million Swedish Kronor in 2024.

What does SLP do?

SLP develops and sells spare parts suitable for Volvo, Scania, and Renault in the commercial vehicle sector, as well as for Volvo Penta and Scania in the marine and industrial sectors. For the boating sector, spare parts for Volvo Penta and Scania marine diesel engines are particularly interesting.

The product range includes seals, water pumps, oil pumps, turbochargers, pistons, bearings, cylinder liners, engine gasket sets, starters, alternators, parts for cooling, fuel supply, and other engine components. SLP can thus be found not only for simple maintenance parts but also for parts required for repairs or engine overhauls.

Where does SLP produce?

SLP describes itself not only as a dealer but also as a company with its own product development and production. According to its own statements, over 65 percent of the products come from production lines established by SLP itself and based on its own drawings. Most of these parts are produced in Europe, according to SLP.

This does not mean that every single SLP part is necessarily manufactured in Sweden. For aftermarket spare parts, various specialized manufacturing companies may be involved depending on the product group. However, SLP makes it clear that design, tools, quality specifications, and product development play an important role within the company.

The automated central warehouse is also located in Kumla. According to the company, a production facility where repair kits are assembled is located directly next to the warehouse. This is relevant for the marine sector because many SLP products are offered not only as individual parts but also as complete repair or overhaul kits.

Is SLP an original manufacturer?

SLP is generally not an original equipment manufacturer (OEM) like Volvo Penta or Scania. The parts are offered as aftermarket spare parts and are designed to be suitable for specific engines, machines, or applications.

In practice, this means that an SLP part can be an alternative to an original reference number, but it usually does not come from the original engine manufacturer. Therefore, before purchasing, it should always be carefully checked whether the part number, engine type, year of manufacture, version, and technical specifications match.

Especially with Volvo Penta and Scania, there are many engine variants that appear similar externally but can differ in detail. A precise assignment is therefore more important than a general engine designation.

Why are SLP parts interesting for the marine sector?

Many boat engines remain in use for decades. This is especially true for robust Volvo Penta and Scania diesel engines. Such engines are often not replaced as long as maintenance, repair, and overhaul are economically viable.

However, original parts for older engines are not always available. Some parts are no longer produced, have long delivery times, or are difficult to obtain. In such cases, aftermarket manufacturers like SLP can play an important role.

This is not just about the price. Often, it's simply about being able to continue maintaining an existing engine. Especially with older marine diesel engines, a suitable spare part can be crucial for whether a repair is still meaningfully possible at all.

What experiences are there with SLP?

SLP is an established brand in the European market for heavy-duty diesel engines and commercial vehicle parts. The company states that it delivers to 91 countries and has a product range of almost 17,000 products. According to SLP, the annual number of deliveries is over 100,000 or around 120,000, depending on the company website and presentation.

In the marine sector, SLP is particularly found where technically robust spare parts for Volvo Penta or Scania Marine are needed. This includes classic wear parts, but also components for repairs to the diesel engine.

As with all spare parts, practical experience largely depends on correct selection and professional installation. A correctly assigned spare part can function reliably. However, an incorrect reference number, a different engine version, or an assembly error can lead to problems even with high-quality parts.

Our conclusion on SLP Swedish Lorry Parts

SLP Swedish Lorry Parts is a Swedish supplier of aftermarket spare parts for heavy-duty diesel applications. The company is based in Norsborg near Stockholm, operates a central warehouse in Kumla, and develops many parts based on its own drawings and tools.

For boat owners, SLP is particularly interesting for Volvo Penta and Scania marine engines. Especially for older engines where original parts are expensive, difficult to obtain, or no longer available, SLP spare parts can be a factual and practical alternative.

The decisive factor always remains the precise assignment via engine type, part number, dimensions, and technical data. Then, SLP parts can help to maintain, repair, and continue to operate existing boat engines reliably in the long term.
