H&R 29991-1 Sport Springs Lowering Kit

H&R Sport Springs deliver the perfect balance of improved handling, aggressive stance, and comfortable ride quality for enthusiasts who demand performance without compromise. Engineered and manufactured in H&R's ISO 9001 certified facility in Germany, these sport springs transform your vehicle's appearance and driving dynamics while maintaining street-friendly comfort.

Premium German Engineering:

• Manufactured from proprietary 54SiCr6 spring steel with 290,000 psi tensile strength for exceptional durability and resiliency
• Precision-engineered spring rates provide increased control and reduced body roll compared to factory springs
• Progressive spring design maintains ride comfort during normal driving while stiffening under load

Performance Benefits:

• Lowers vehicle ride height 1.5 to 2.0 inches on average for improved aerodynamics and aggressive appearance
• Reduces center of gravity for sharper turn-in response and reduced body roll in corners
• Optimized spring rates enhance tire contact with the road surface for better grip
• Superb ride quality maintains daily driver comfort—no harsh, jarring ride

H&R Sport Springs are designed specifically for street use and work with factory shock absorbers, though they perform even better when paired with performance dampers. Each spring is cold-wound and shot-peened for maximum strength, then powder-coated for corrosion resistance and long service life.
