Key Features

  • ENGINEERED FOR EMERGENCY AND FLEET VEHICLES -- For hardworking first responder, municipal, fleet and jobsite vehicles and features 10-stage valving that adjusts to road extremes to help handle frequent stops, heavy loads and high miles
  • IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
  • STRONG AND DURABLE -- Double welded, including arc welds up to 360-degrees, for durability while shouldered bushing and bonded bushing (on most applications) delivers quality
  • BUILT TO LAST -- Heavy-duty nitrocarburized rod (on most applications) and sintered iron piston enhance durability for longer service life
  • LONGER SERVICE LIFE -- Bearing with PTFE coating reduces friction between rod and rod guide combined with nitrocarburized piston rod provides durability and longer service life (most applications)
  • CONSISTENT RIDE -- OE all-weather fluid contains special modifiers to handle extreme temperatures and help reduce friction and ensure smooth rod reaction
  • CONTROL AND DURABILITY – PTFE-banded piston helps reduce friction between the piston and pressure tube to enhance responsiveness to changing road surfaces for smooth operation

    Couldn't locate the parts for 2013 Civic Si Sedan. Front struts are an Anomaly found them at Capital autoparts. Great service and great parts. Shipping by CanPar sucked however

  • July 2026

    Great customer service. I placed an order for wheels and tires and it was an easy transaction. Make sure you read the expected lead times for delivery however. I misread that part, but the order did arrive in the correct timeframe stated. The Hostile rims and Hercules tires look great. Thank you
