H&R 40006-12 Sport Cup Kit Spring and Shock Suspension Kit

The H&R 40006-12 Sport Cup Kit is a complete, application-engineered spring and shock suspension system built for drivers who demand a lower, more aggressive stance without sacrificing everyday drivability. Backed by over 25 years of H&R suspension design expertise, this kit goes well beyond a generic "matched" spring and shock pairing — every component is purpose-built and tuned to work together as a cohesive unit.

Key Features:

• Application-specific engineering: Springs and shocks are designed and calibrated together for a seamless, optimized suspension package
• Progressive spring rate: Delivers a lower ride height while maintaining superior ride comfort under varying load conditions
• Custom-valved performance shocks: Matched precisely to the included springs for consistent damping performance
• Approximately 2.0" of ride height reduction: Front lowering of approximately 1.8" and rear lowering of approximately 1.7" for a pronounced performance stance
• Lower center of gravity: Improves handling and cornering response over stock suspension
• Street-engineered: Designed to perform on public roads, balancing performance handling with uncompromised daily comfort

Unlike off-the-shelf performance components that require guesswork to match, the H&R Sport Cup Kit arrives as a fully integrated suspension solution. The result is a package that outperforms and outrides mismatched individual components, delivering a cohesive upgrade in handling, ride quality, and appearance in a single precision-engineered kit.
