Superlift Shock Boots are constructed from a high-quality, durable polyurethane material for maximum longevity and minimal fading. The shock boots help protect the shock's piston rod from dirt, mud and other debris. This protection can prolong the life of your shocks. Superlift Shock will fit any Superlift shock absorber or Superlift steering stabilizer. The boots are sold separately and include a nylon zip-tie and Superlift decal.
