Reliability and durability, even in the most demanding conditions.
For heavy-duty vehicles, performance is measured not by acceleration but by operational continuity. These vehicles face high loads and continuous duty cycles, covering up to hundreds of thousands of kilometres each year and more than a million over their service life. Heavy-duty vehicles redefine what strength and reliability mean.
Streparava addresses every factor that affects component service life: materials, treatments and manufacturing processes. Steel, cast iron and aluminium: each is selected to suit its operating conditions. Specific treatments and coatings such as lapping, isotropic finishing, nitriding, carburising, phosphating, DLC and PVD: each choice helps reduce wear and maintain consistent performance.
Innovation presents another challenge. Streparava has developed complex systems in-house for heavy-duty applications, including Easy Lift, a variable valve actuation (VVA) system: the result is a combination of high performance and reliability that is unique on the market.
Streparava is also one of the few companies capable of developing complete engine braking systems for trucks.
The result is an engine designed for durability and lower emissions, capable of delivering operational continuity and reliability even under the most demanding operating conditions.
