Restore the designed control and handling of your Mazda CX-7 with the KYB Excel-G Suspension Strut 339155, a nitrogen gas-charged, twin-tube unit that mounts in the front right position. It drops in as a direct-fit replacement for the 2007-2012 Mazda CX-7, and because the Excel-G is built on the same KYB OE assembly lines using the same OE-quality components, it is calibrated to restore original, designed performance rather than change it — earning the OEA (Original Equipment for the Aftermarket) classification.
- Twin-tube gas design: nitrogen gas-charged, twin-tube construction that includes every quality component found in KYB's 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 manage tire contact, steering response, and body movement.
- Strong strut body: KYB's thick strut bodies and brackets minimize flex to help maintain correct alignment.
KYB designed the Excel-G to help keep Electronic Safety Systems performing as intended, since those systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended. To reduce noise and vibration, KYB recommends installing new strut mounts (part number SM5692), and a KYB Strut Boot (part number SB105) helps protect the strut from dirt, debris, and salt.
