The benefits of a Mercedes-Benz Genuine Remanufactured long block.

There are numerous benefits to a long block. These include reduced non-operational time due to high availability and, at the same time, quick installation thanks to pre-assembled valves in the cylinder head. In addition, non-operational time is reduced in comparison with short blocks, as the engine does not have to be built up from single components. We keep more than 4,000 engines in our warehouses, ready and waiting for one to be installed in your vehicle.

A long block is a practical solution for an engine that has suffered considerable damage. This could be in the form of crankshaft damage affecting the crankcase and cylinder head.

There are benefits to purchasing a long block in terms of price as well. You will be reimbursed for your old engine, which will help to reduce the total price of your engine. The long block is a low-cost alternative to a short block if this is purchased in a single transaction and additional spare parts are required. If you are looking for an engine for your Mercedes-Benz truck with a fully remanufactured cylinder head, the long block is the ideal choice.

With a Mercedes-Benz Genuine Remanufactured long block, you receive a guarantee for up to two years2), because we are certain that its functionality, longevity and quality will meet even the most exacting requirements. Engines undergo extensive testing and endurance trials. Each long block is tested on a test stand before dispatch to check that it meets the strict criteria for series production.

As a premium product, the long block offers a long service life and high efficiency.

Thanks to our consistent standard of quality, you can expect a genuine Mercedes-Benz product with a service life and efficiency equivalent to those of a new product. For example, all rotating component parts, such as camshafts and crankshafts, are finely balanced in line with the latest state-of-the-art new part production methods. Furthermore, all wear parts, such as seals, bearing shells and pistons, are replaced with new parts. That means that your truck engine is restored to the same condition as a new engine, with low fuel consumption and wonderfully smooth running.

Find out for yourself and ask your Mercedes-Benz service partner about Mercedes-Benz replacement engines for your truck.
