Restore the designed ride control, stability, and handling of your GM sedan with the KYB Excel-G Suspension Strut 335037, a front strut that drops in as a direct-fit replacement for the 2000-2005 Buick LeSabre, 2000-2005 Cadillac DeVille, 2001-2003 Oldsmobile Aurora, and 2000-2005 Pontiac Bonneville. Built as a KYB-recommended OEM replacement, the Excel-G is a nitrogen gas-charged, twin-tube strut made on the same KYB OE assembly lines with the same OE-quality components, calibrated to restore original designed performance rather than change it — a classification KYB calls OEA (Original Equipment for the Aftermarket).
- Twin-tube, gas-charged design: nitrogen gas-charged for consistent damping.
- 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 bodies and brackets: minimize flex to help maintain correct alignment.
KYB helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes, and tires working as intended. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5276), and you can protect your new struts from dirt, debris, and salt with a KYB Strut Boot (part number SB101).
