Robust hydraulic lock-out: Prevents over-extension of the suspension, top-out of the piston and averts damage to the seal assembly - on most applications PTFE coated bearing: Reduces friction during operation between the rod and rod guide, improving durability - on most applications 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 provide up to 13,100 lbs. (6,395 kg) tensile strength for maximum durability - when required 2-inch (50.8 mm) or 2-1/4-inch (57.2 mm) reserve tube: More fluid for more consistent performance - when required 1-3/8-inch (35 mm) bore: Larger bore than most shocks to provide more efficient and consistent control - on most applications .05-inch Pressure tube withstanding pressure of 9KPSI 10-stage valving: Reacts to wide range of driving conditions - on most applications
