KYB 335065 Suspension Strut - Front

KYB Excel-G Front Suspension Strut

KYB Excel-G 335065 is a front suspension strut built to restore original ride control, stability, and steering response. It is a recommended OE replacement for select Buick Lucerne and Cadillac DTS applications, with calibration focused on factory-style handling rather than changing the vehicle’s character.

Key Features

• Nitrogen gas-charged, twin-tube suspension strut design
• Vehicle-specific, hand-assembled damping valves for controlled tire contact and body motion
• Triple-lip fluid seal to help reduce oil and gas leakage
• Strong strut body and bracket construction to help minimize flex and maintain alignment
• R-stop design for rebound control
• Compatible with electronic safety systems when the suspension is operating as designed
• Part number 335065

Product Details

The KYB Excel-G line is built on KYB OE manufacturing processes and uses OE-quality components to return the suspension to its original performance profile. For drivers searching for a front strut for a 2006-2011 Buick Lucerne or a 2006-2011 Cadillac DTS front suspension strut, this part is calibrated to support predictable braking, lane change response, and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 72321) for the same application.

Fits 2006-2011 Buick Lucerne, front; recommended OEM replacement; without Magnetic Ride Control; Excel-G. Fits 2006-2011 Cadillac DTS, front; recommended OEM replacement; excluding electronic suspension; with FE1 soft ride suspension; excluding limo, hearse, and armored body; Excel-G. KYB 335065 is also listed as an OE-style replacement for select GM applications.

Common Issues This Strut Can Address

• Excessive bounce after bumps or dips
• Loose or delayed steering response
• Reduced braking stability during weight transfer
• Uneven tire contact caused by worn damping control
• Body movement that feels less controlled in turns or lane changes

Installation Notes

Verify vehicle equipment before ordering, especially Magnetic Ride Control, electronic suspension, and FE1 soft ride suspension details. Confirm front-position fitment and compare the original strut dimensions to the listed compressed length of 13.62 in., extended length of 19.41 in., and stroke length of 5.79 in. Use a KYB strut boot, part number SB103, to help protect the new strut from dirt, debris, and road salt.

Quality Assurance

KYB is a major OE shock and strut supplier, and the Excel-G line is assembled on the same production lines used for OE applications. The design focuses on restoring factory ride control and maintaining the suspension behavior the vehicle was engineered to deliver.
