H&R 31017-1 Sport Cup Kit - Lowering Spring & Shock Suspension Package

The H&R 31017-1 Sport Cup Kit is a precision-engineered spring and shock suspension package built for enthusiasts who demand aggressive lowering without sacrificing everyday drivability. Delivering more than 2.0 inches of ride height reduction, this Sport Cup Kit is designed and produced in H&R's ISO-certified manufacturing facility in Germany.

Unlike generic spring-and-shock pairings, the H&R Sport Cup Kit is engineered as a unified system — the springs and shocks are purpose-built and tuned together for a specific vehicle application. This co-development process eliminates the guesswork and mismatch issues common with off-the-shelf component combinations, resulting in optimal suspension damping, precise body control, and a lower center of gravity.

Key Features:

• Over 2.0 inches of lowering for an aggressive, street-performance stance
• Application-specific spring and shock pairing — engineered together, not mixed and matched
• Progressive spring rate design retains ride comfort on daily-driven streets while improving handling response
• Lower center of gravity reduces body roll and improves cornering control over stock suspension
• ISO-certified German manufacturing ensures consistent quality and performance
• Outperforms separate off-the-shelf performance suspension components in both comfort and handling
• Complete, ready-to-install kit — includes matched springs and performance shocks

The Sport Cup Kit steps up from H&R's Touring Cup Kit with additional lowering and enhanced performance characteristics, making it the ideal choice for the driving enthusiast who wants more from their suspension. The result is a cohesive, factory-tuned package that transforms both the stance and the dynamics of your vehicle in one install.
