KYB 335045 Suspension Strut - Front

KYB Excel-G Front Suspension Strut

KYB Excel-G part number 335045 is a front suspension strut built to restore original ride control, stability, and steering response. It is an OE-style replacement for Buick Park Avenue and Buick Riviera applications, with calibration focused on factory-like handling rather than changing the vehicle’s character.

The Excel-G line is KYB’s OEA replacement series, produced on the same assembly lines and with the same OE-quality components used in KYB original equipment manufacturing. For Buick Park Avenue and Buick Riviera owners looking for a front strut that matches the vehicle’s designed suspension behavior, 335045 is a direct-fit service part for the listed applications.

Product Line Details

KYB Excel-G is the brand’s OE replacement line for drivers who want suspension performance calibrated to original specifications. Part number 335045 follows that approach with OE-style damping and construction intended to restore the Buick Park Avenue and Buick Riviera’s front-end control, lane-change response, and braking stability.

What This Strut Helps Address

• Excessive front-end bounce or float
• Reduced steering precision during lane changes
• Nose dive under braking
• Uneven tire contact caused by worn damping
• Noise and vibration from aged suspension components
