H&R 31017-3 Sport Cup Kit Lowering Spring & Shock System

The H&R 31017-3 Sport Cup Kit is a precision-engineered, application-specific suspension package that delivers aggressive lowering of more than 2.0 inches alongside genuine street performance. Unlike generic spring-and-shock pairings, this kit is the product of over 25 years of H&R suspension engineering expertise — with every component designed and validated together from the ground up.

Because the springs and shocks in the H&R Sport Cup Kit are co-developed as a unified system, they work in perfect harmony to produce a lower stance, sharper handling response, and a ride quality that standalone off-the-shelf components simply cannot match. There is no guesswork in tuning — fit the kit and experience a fully optimized suspension setup from day one.
