H&R 31852-1 Sport Cup Kit Performance Lowering Spring & Shock System

The H&R 31852-1 Sport Cup Kit is a complete, application-specific spring and shock package engineered together from the ground up to deliver a street-performance suspension with aggressive, super-low stance. Built on over 25 years of H&R suspension design experience, this kit eliminates the guesswork of pairing mismatched components.

Key Features:

• Delivers more than 2.0 inches of lowering for a sleek, aggressive ride height
• Springs and shocks are co-engineered as a matched system — not generic off-the-shelf components paired together
• Application-specific tuning provides improved handling response without sacrificing ride comfort
• Outperforms separately sourced spring and shock combinations in both performance and comfort
• Precision-engineered for street use with a sport-tuned damping profile
• Complete kit includes all necessary springs and shock absorbers

Unlike so-called "matched" packages from other brands, the H&R Sport Cup Kit is purpose-built so that every component works in concert. The result is a cohesive suspension system that delivers enhanced cornering capability, reduced body roll, and a dramatically lowered profile — all while maintaining daily-driver comfort.
