Bring back tight, controlled front damping on your Mazda RX-7 with the KYB Excel-G Gas Cartridge 363003. This nitrogen gas-charged, twin-tube strut cartridge drops in as a direct-fit front replacement for the 1979-1980 Mazda RX-7 (All). KYB builds the Excel-G on the same OE assembly lines and calibrates it to restore the vehicle's original, designed performance rather than change it — earning its OEA (Original Equipment for the Aftermarket) classification.

  • Twin-tube, nitrogen gas-charged design: the Excel-G build KYB uses across its global OEM products.
  • Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
  • Vehicle-specific damping valves: hand-assembled in-house to help manage tire contact, steering response and body movement.
  • Thick strut body and brackets: designed to minimize flex and help maintain correct alignment.

Specs: stroke length 14.84 in, compressed length 15.67 in, extended length 22.72 in, with a 14x1.50 upper mount and an internal rebound bumper. A dust cover and bump stop are not included. Country of origin: Japan. Sold individually; the RX-7 uses two up front, so order 2 for a complete front pair.
