H&R Race Springs 2.50" I.D. 54SiCr6 Steel Lightweight High Tensile Alloy

H&R Race Springs — 2.50" I.D. 54SiCr6 Lightweight High‑Tensile Alloy Precision German engineering and advanced materials combine in the H&R 2.50" I.D. Race Springs. Made from special lightweight 54SiCr6 spring steel, these race springs deliver exceptional strength with reduced mass for faster response and improved suspension performance. Lightweight, high tensile alloy: Thinner wire construction yields an average 15% weight reduction versus competitors while maintaining strength. Increased travel: About 10% more travel for a given spring rate, enhancing articulation and control on track. Wide range of configurations: Main spring lengths from 6" to 18" and extensive spring rate options to suit street, track, and bespoke setups. Tender spring option: Trapezoidal (flat) wire tender springs with low block height maximize travel and durability in demanding motorsport applications. Pre-blocked for longevity: Factory pre-blocking prevents setting or sagging under repeated loads. H&R also offers a comprehensive 60mm I.D. Race Spring program with hundreds of main and tender springs, covering lengths from 80mm to 300mm and rates from 25 N to 700 N. Ideal for Porsche GT3 and other Euro-spec performance cars, these springs provide tunability and consistency for professional setups. Choose H&R Race Springs for reduced unsprung weight, improved travel, and race-proven durability — engineered in Germany for competitive performance.
