2007-08 Silverado/Sierra Sport Suspension Package is designed to enhance the truck's already great handling characteristics. The package was designed together with Eibach Springs, the leading producer of performance suspension systems for cars and trucks and will work on the standard cab, extended cab and crew cab models.
The package includes two new progressive rate front springs and two unique rear spring extenders resulting in a 2" drop both front and rear in ride height. This produces a lower center of gravity for the truck resulting in flatter cornering and increased resistance to rollover while still maintaining excellent ride quality, since the stock shock absorbers are used. It also reduces the large gap between the top of the tires and the body of the truck dramatically improving the appearance.
