H&R 31054-3 Sport Cup Kit - Lowering Spring & Shock Absorber Package

The H&R 31054-3 Sport Cup Kit is a precision-matched spring and shock absorber package engineered to deliver a street-ready performance suspension with an aggressive, low stance. Designed and manufactured at H&R's ISO-certified facility in Germany, this kit is purpose-built as a cohesive system — not a collection of off-the-shelf components — ensuring optimal damping, spring rate compatibility, and suspension geometry from the start.

The Sport Cup Kit steps up from the Touring Cup Kit with additional lowering and stiffer spring rates, making it the ideal choice for the performance-focused enthusiast who wants a noticeably lower ride height and sharper handling without the cost or complexity of a full coilover setup. Progressive-rate springs maintain compliance over small road imperfections while delivering increased firmness under hard cornering and weight transfer.

Key Features:

• Lowering Range: Approximately 2.1" front / 1.7" rear
• Matched system: Custom-valved performance shocks paired specifically to application-tuned progressive springs
• Progressive spring rate: Remains compliant on small bumps; stiffens progressively under load — approximately 50% stiffer than OEM springs overall
• Lower center of gravity: Reduces body roll and improves cornering performance over stock
• German-made: Designed and produced in H&R's ISO-certified manufacturing facility
• Bolt-on fitment: Compatible with stock strut and shock mounts

What's Included:

• 4 application-specific progressive-rate lowering springs
• 4 custom-valved performance shock absorbers

The H&R Sport Cup Kit is the smart alternative to mixing unmatched springs and shocks. By engineering the springs and dampers together, H&R eliminates the guesswork and delivers a suspension package that is both more capable and more comfortable than mismatched aftermarket components.
