SANLUIS Rassini
is the world's largest designer and manufacturer of leaf springs for light vehicles. We engineer and produce leaf, parabolic, and coil springs for original equipment manufacturers (OEM) in North and South America. As utilized in engineering the R4Tech Suspension system, we use the latest computer-aided engineering (CAE) tools to meet their stringent requirements of the OEMs.
Simulation | We model all new springs and assemblies in computer simulation. This advanced software provides data on braking and cornering forces for the springs. It also predicts and maps wheel path, spring wrap, axle windup and other characteristics of the suspension.

Finite element analysis (FEA) | We use this complex suite of software to identify stress points in springs, brackets and other suspension components. We simulate stress loads experienced in the real world and use that data to engineer components for strength and durability.
3D Imaging | Using 3D Imaging equipment and software, we capture vehicle geometry data from the vehicles that we build suspension systems for. This provides extremely dependable data, allowing us to design and engineer components that fit exact every time. We can also lay our design over these images to ensure that we have proper clearances and alignment even before we build the first prototype.
Testing | Once our components are designed, we build prototypes and begin performance and durability testing. All components are tested and measured to compare what we found in the digital design phase. Durability testing of the components is performed with multi-axis spring testers.
Quality Control Certifications | All SANLUIS Rassini operations are certified ISO/TS-16949 and ISO-14001, adhering to strict OEM standards for safety, durability and function.
Measuring | Measuring components and comparing to nominal CAD models is one of the quality control steps taken before approving production.
Design tools | SANLUIS Rassini utilizes the latest design tools and CAE packages for product development. Our engineering team designs the suspension to work within the OEM frame architecture.
