Shock Absorbers control spring movement that assists in keeping your tires in contact with the road. They are critical suspension components that can affect tire wear, braking, comfort of operator and the overall life of other related systems. Shocks should be a part of a routine inspection and tested by a repair technician during maintenance.

Double Lip Oil Seal Design:
• High wear, impact & pressure resistant
• Precision controlled Nitrile double lip structure process produces leakproof radial seal better than triple lip
• Added cushion below guider prevents striking the piston directly & leads to longer product lift

High Precision Metal Stamping & Tube material:
• Extra Strength ! Quality steel w/ close tolerances & maximized cross sectional wall thickness. Results in a stable work environment for the piston

Piston Rod:
• 42 manufacturing process to produce microcrack free chrom plated piston rod
• Tolerance of piston diamter < 0.0004"
• Hardness held to 45-55 HRC after quench & chromed plating, improving corrosion resistance

Proprietary Valve System:
• Durable, stable, high quality, patented technology
• Piston & compression valve use 2-way structure design, damping force control is better than 1-way valve
• Improved stopper assembly provides valve block, plate & throttle slice position more space for adjusting damping force & stability
• Intergrated proprietary powder metal design improve tolerances & impact resistance allowing for superior oil sealing between components & longer life

Carbon Fiber Wear Ring on the Piston Valve:
• High wear & temperature resistant material
