H&R 52770 Sport Springs Lowering Coil Spring Set

The H&R 52770 Sport Springs are a direct-drop replacement for factory coil springs, engineered to deliver a lower, more aggressive stance combined with a noticeably improved driving experience. Designed and manufactured at H&R's ISO 9001 certified facility in Germany, these sport lowering springs are built to exacting standards for long-term durability and consistent performance.

Each spring is formed from special (HF) 54SiCr6 spring steel rated at 290,000 PSI tensile strength, then shot-peened to extend service life by more than 200% compared to standard springs. The result is a spring that is stronger, more resilient, and longer-lasting than conventional automotive coil springs.

Key Features:

• Lowers vehicle ride height an average of 1.5–2.0 inches for a sportier stance and reduced fender gap
• Progressive spring rate design delivers superb ride quality and comfort — firm when needed, compliant when cruising
• Lowers center of gravity to reduce body roll and improve cornering response
• Reduced wind resistance signature for a more streamlined profile
• Manufactured from 54SiCr6 high-fatigue spring steel for unrivaled tensile strength and resiliency
• Shot-peened for over 200% greater service life versus standard springs
• ISO 9001 certified manufacturing — engineered and produced in Germany
• TÜV approved construction

H&R Sport Springs are a bolt-in upgrade that balances sporty performance with everyday street comfort. Professional installation and a post-installation wheel alignment are recommended.
