Carli Suspension's Signature Series Front Shocks provide three inches of lift and a generous 10 inches of travel to deliver enhanced suspension articulation in off-road situations. For added performance and durability Carli uses zinc plating, a clearcoat finish, and quality bushings to protect the shocks from corrosion. To further enhance the durability and performance of the shocks, Carli adds boots that serve as protective covers for the shock shafts, shielding the shocks from dirt, debris, and other potential sources of damage.
