H&R 31019-1 Sport Cup Kit Street Performance Spring & Shock Suspension Package

The H&R 31019-1 Sport Cup Kit is a complete, application-engineered spring and shock absorber package designed to deliver aggressive lowering, sharper handling, and a confident street stance. Built on decades of German suspension expertise, this kit goes well beyond a generic matched spring-and-shock combo — every component is developed and calibrated together as a cohesive system for a specific platform.

Key Features:

• Significant ride height reduction — lowers approximately 2.1" in the front and 1.7" in the rear for a dramatically improved stance
• Progressive spring rate design — remains compliant over small road imperfections while providing increased stiffness under load; approximately 50% stiffer than OEM springs
• Matched springs and shocks engineered together — eliminates damping mismatch issues common with mixing off-the-shelf components
• Application-specific calibration — springs and shock absorbers are tuned for the specific chassis, suspension geometry, and spring rates of the target vehicle
• Lowers center of gravity and roll center — reduces body roll and improves weight transfer for more responsive cornering
• Street-engineered performance — designed for daily driver use while delivering performance suspension characteristics
• Made in Germany — manufactured to ISO quality standards by H&R Spezialfedern GmbH & Co. KG

The Sport Cup Kit represents a step up from H&R's Touring Cup Kit, offering more aggressive lowering and stiffer spring rates for enthusiasts who prioritize handling precision. The kit fits with factory strut and shock mounts for a straightforward installation. Because the shocks and springs are engineered as a unit, the system avoids the under-damping or travel mismatches that can occur when components are sourced separately.

This kit includes 2 front struts and 2 rear shocks, along with the matched H&R sport springs — everything needed for a complete suspension upgrade in a single precision-engineered package.
