Help restore the designed control and handling of your 2003-2006 Acura MDX with the KYB Excel-G Suspension Strut 339073, a nitrogen gas-charged front-left gas strut. Built on KYB's OE assembly lines from the same OE-quality components, the Excel-G is calibrated to bring back the vehicle's original, designed performance rather than change it — a classification KYB calls OEA (Original Equipment for the Aftermarket).

  • Nitrogen gas-charged, twin-tube design: includes the quality components found in KYB's global OEM products and is a preferred choice among professional technicians.
  • Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
  • Vehicle-specific, hand-assembled damping valves: tuned to manage tire contact, steering response and body movement.
  • Strong, thick strut bodies and brackets: designed to minimize flex and help maintain correct alignment. Made in USA.

This is the front-left corner and is sold individually; replacing the left and right struts together as a matched pair is recommended for balanced handling. KYB suggests protecting new struts with a KYB Strut Boot (SB104) and installing new strut mounts (SM5211) to reduce the chance of noise and vibration. See the Buyer's Guide tab for engine-level fitment.

What type of strut is the KYB Excel-G?

It is a nitrogen gas-charged, twin-tube strut built on KYB's OE assembly lines using the same OE-quality components, classified as OEA (Original Equipment for the Aftermarket).

Do I need any additional parts?

KYB recommends its Strut Boot (SB104) to protect the strut from dirt and debris and new strut mounts (SM5211) to help reduce the chance of noise and vibration.
