H&R 29904-2 Sport Cup Kit - Spring & Shock Suspension System

The H&R 29904-2 Sport Cup Kit is a precision-engineered spring and shock suspension system built for enthusiasts who demand aggressive lowering without sacrificing street-driven ride quality. Unlike generic "matched" spring and shock packages, this kit is purpose-built with springs and shocks co-developed from the ground up to work as a unified system — eliminating the guesswork from performance suspension selection.

Key Features:

• Approximately 2.0 inches of rear lowering for a performance stance and reduced center of gravity
• Progressive spring rate design retains superior ride comfort while improving handling dynamics
• Custom-valved performance sport shocks matched precisely to application-specific springs for cohesive suspension behavior
• Application-specific engineering — springs and shocks are developed together for each vehicle, not adapted from a universal design
• Kit includes front shocks, rear shocks, and rear springs
• Shocks sourced from manufacturers with OEM expertise and international motorsport experience
• All H&R springs are 100% made in Germany, meeting TÜV safety standards and ISO 9001 quality certification

The Sport Cup Kit builds on the features of H&R's Touring Cup Kit lineup with additional lowering — ideal for the performance enthusiast looking for a more aggressive drop. Note: On applicable vehicles, a camber adjustment kit may be recommended when lowering exceeds 2.0 inches. Front torsion bar adjustment may be required on certain platforms for ride height tuning.
