Product Details

The KYB Excel-G 3410112 is part of KYB’s OEA-focused product line, which is engineered to match original equipment behavior rather than alter it. For rear suspension service on the Buick Envision and Cadillac XT4, this shock absorber is selected to bring back controlled damping, consistent body motion, and predictable handling characteristics. The 3410112 is a practical OE-style replacement for vehicles that need restored ride control without changing the factory feel.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during braking and lane changes
• Loose or unsettled rear suspension feel
• Uneven damping response from worn shock absorbers
• Loss of factory ride control on Buick Envision and Cadillac XT4 rear suspension

Installation Notes

• Verify rear fitment by year, model, and suspension configuration before installation.
• Does not fit vehicles with electronic controlled suspension.
• Confirm mount style and dimensions against the original shock absorber: E2 lower mount and S1 upper mount.
• Inspect related suspension components such as mounts, bushings, and tires during replacement.

Quality Assurance

KYB is a major OE shock and strut supplier, and Excel-G is produced on the same KYB assembly lines using OE-quality components. The line is calibrated to restore original vehicle performance for the listed applications.
