The H&R 60mm I.D. race spring is a single main race spring (100mm length, 380 N/mm) for suspension tuning and high-load track use. Engineered in Germany from (hf) 54SiCr6 spring steel, these springs average 15% lighter and afford about 10% more travel than many competitors. H&R's extensive 60mm line spans 80–300mm lengths and 25–700 N/mm rates, offers tender springs for extra travel, and ships pre-blocked at the factory to minimize sag.
