Keep your GM sedan planted and controlled with the KYB Excel-G Front Suspension Strut 335065, a nitrogen gas-charged, twin-tube replacement strut that drops in as a direct-fit for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS. KYB builds the Excel-G on the same OE assembly lines it supplies to new-vehicle manufacturers, using OE-quality components calibrated to restore the vehicle's originally designed control and handling rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: the professional technicians' preferred choice, built with 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 correctly manage tire contact, steering response and body movement.
- Strong, thick strut body and brackets: among the industry's thickest, minimizing flex to help maintain correct alignment in all conditions.
This is a KYB-recommended OEM replacement front strut that also helps keep electronic safety systems performing as designed. Protect your new struts from dirt, debris and salt with a KYB Strut Boot, part number SB103.
