H&R 29991-2 Sport Springs Lowering Kit

The H&R 29991-2 Sport Springs deliver the ideal balance of improved handling, aggressive lowered stance, and everyday street comfort. Engineered and manufactured 100% in Germany at H&R's ISO 9001 certified and TÜV-approved facility, these springs are built to exacting standards that drivers and enthusiasts have trusted for decades.

Constructed from a proprietary (hf) 54SiCr6 spring steel with a tensile strength rated at 290,000 PSI, each spring is also shot-peened to extend service life by more than 200%. The progressive spring rate design allows the suspension to adapt dynamically — softening over everyday road imperfections and firming up during spirited driving or cornering.

Key Features:

• Lowers vehicle ride height an average of 1.5–2.0 inches for a sportier, more aggressive stance
• Progressive spring rate delivers superb ride quality without the harshness of stiffer aftermarket setups
• Lowers center of gravity to reduce body roll and improve cornering response
• Reduced fender-well gap for a cleaner, more purposeful appearance
• Shot-peened 54SiCr6 spring steel construction — lightweight, strong, and highly resilient
• ISO 9001 certified and TÜV approved
• 100% manufactured in Germany
• Lifetime warranty to original vehicle owner

H&R Sport Springs are a direct OEM replacement upgrade, designed to work seamlessly with factory shock absorbers, though pairing with performance aftermarket shocks is recommended for optimal results. Professional installation and a post-install alignment are advised.
