Product Details

KYB Excel-G 349136 is engineered for rear suspension service where restoring factory ride behavior matters more than changing it. It uses OE-calibrated damping to help control rebound and compression on the rear of the vehicle, which is important for braking stability, lane-change response, and consistent tire contact. This part cross-references Monroe Shocks & Struts 5647 for the same application.

Compatible With 2014-2020 Chevrolet Impala, rear; 2014-2017 Buick Regal, rear; 2014-2016 Buick LaCrosse, rear; 2016 Chevrolet Malibu Limited, rear; 2013-2015 Chevrolet Malibu, rear; 2012-2013 Buick LaCrosse, rear; 2011-2013 Buick Regal, rear; and 2010-2011 Buick LaCrosse, rear. Part number 349136 is a practical OE-style choice for rear suspension repair on these GM sedans.

What It Helps Address

• Excessive rear-end bounce after bumps
• Reduced stability during braking or lane changes
• Uneven or inconsistent tire contact on the road
• Loose, worn, or undercontrolled rear suspension feel
• Ride quality that no longer matches factory behavior

Installation Notes

Verify rear fitment by year, make, model, and suspension configuration before installation. Some applications note that additional components, dust covers, or bushings may be required, and certain vehicles exclude active, electronic, or sport suspension systems. Confirm the mounting style and dimensions before ordering: compressed length 14.37 in., extended length 22.32 in., stroke length 7.95 in., lower mount type E2(14X40), upper mount type S1.

For best results, inspect related suspension parts, mounting points, and tire condition during replacement. Proper installation and alignment checks help the shock absorber perform as intended.

Quality Assurance

KYB is a global OE supplier of shocks and struts, and the Excel-G line is built on the same manufacturing lines used for original equipment supply. The part is assembled with OE-quality components and calibrated to restore designed performance for the listed GM applications.
