B G Springs: Drawing on over 150 years of spring design and manufacturing expertise, B&G S2 Sport Springs are engineered to improve handling while maintaining safety and ride quality. By redesigning the O.E. Spring and lowering the center of gravity from 1-2.5 inches (depending on vehicle and application) our technicians dramatically improved your vehicles performance and appearance. Incorporating a progressive rate design allow B G springs to offer higher spring rates for improved road hold, while maintaining a comfortable ride for daily driving.
