H&R Sport Springs for 2011–2017 Buick Regal (2WD) reduce fender gap and lower the vehicle's center of gravity to improve handling and reduce body roll. The progressive-rate springs are shot-peened and made from 54SiCr6 spring steel, delivering a balance of ride comfort and sporty control. H&R's sport springs are a commonly chosen single-suspension upgrade to enhance stance and cornering behavior.
