      • PTFE coated bearing: Reduces friction during operation between the rod and rod guide, improving durability
      • Tenneco shouldered bushings: Shouldered bushing and bonded bushing with sleeve designs prevent [bushing walkout] for improved quality and durability - on most applications
      • Nitrogen gas-charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
      • Loop welding technique: Resistance weld with additional 360-degree weld to provide up to 15,000 lbs. (6,804 kg) tensile strength for maximum durability - when required
      • 2-inch (50.8 mm) or 2-3/8-inch (60.3 mm) reserve tube: The 2" (555xx Series) or 2-3/8' (557xx Series) reserve tube holds more fluid or more consistent performance - when required
      • 1-3/8-inch (35 mm) or 1-3/4-inch (44.6 mm) bore: The 1-3/8' (555xx Series) or 1-3/4" (557xx Series) bore is larger than most shocks to provide more efficient and consistent control - when required
