SLP Sport Suspension Pkg. 2007-08 Avalanche/Suburban w/2WD/4WD w/o Autoride.
SLP's 2007-08 Avalanche/Suburban/Yukon XL Sport Suspension Package is designed to enhance the truck's already great handling characteristics.
The package includes four progressive rate front springs and rear springs 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. It also reduces the large gap between the top of the tires and the body of the truck improving the appearance of the truck dramatically. NOTE: Can not be used with SLP dual exhaust #31672, #31673 |
