H&R PULS | Performance Ultra Light Springs

In the dynamic world of motorsport, innovations are crucial to success. Weight plays a central role in the development of high-performance vehicles. Even small savings can make a decisive difference. This is where H&R comes into play with a ground-breaking innovation: the new ultra-light PULS racing springs.

The evolution of H&R racing springs

Over the years, H&R has continuously developed the standard for racing springs further:

• RF – the classic racing spring..
• HRF – the high-strength racing spring, which has already enabled significant progress in terms of strength and weight reduction.
• PULS – the latest innovation that once again pushes the boundaries of what is possible in terms of lightweight construction.

H&R PULS: Lighter, stronger, more innovative

The new PULS springs base upon on a patented steel alloy that makes it possible to achieve a weight reduction of up to 30%, depending on the application and spring geometry. This is particularly invaluable in motorsport, where every gram counts. But PULS springs don’t just offer less weight. They also impress with:

• Higher strength: they withstand extreme loads and offer exceptional toughness.
• Less tendency to sag: They retain their shape even under extreme conditions and ensure consistent performance.
• Increased ductility: Thanks to the use of innovative materials and a special heat and surface treatment, PULS springs have a higher ductility. This enables a more compact yet durable design which is perfect for top motorsport.

Flexibility for different applications

H&R offers the PULS springs in two different application areas to meet the specific requirements:

1. Racing – Short service life:
   In racing, weight saving is crucial. Here, PULS springs offer outstanding weight optimization, which is particularly effective with shorter life cycles. These springs are designed for maximum performance and minimum mass.
2. Special series – long service life:
   For vehicles in special series or in the OEM sector, the springs must have a longer service life. Here, H&R adapts the spring geometry and material to the manufacturer’s specific requirements. Even if the weight reduction with a longer service life is not as significant as in racing, the PULS springs still offer significant advantages in terms of weight and durability.

Conclusion: A milestone in lightweight construction

H&R is setting new standards in lightweight construction with its ultra-light racing springs. They combine low weight with high strength and durability, making them the ideal choice for motorsport and special vehicle series. The PULS springs are more than just another development – they are a revolution that has the potential to change motorsport forever.
