Product Details

The KYB Excel-G line is built to return the vehicle to its original damping characteristics rather than change ride feel. Part number 3440035 uses OE-quality components and KYB calibration to support consistent rear suspension performance on the Buick Encore and Chevrolet Trax. This part cross-references Monroe Shocks & Struts 5699 for the same application.

The rear fitment covers 2013-2022 model years across these applications, with manufacturer notes calling for strut and coil spring assembly replacement according to service instructions where applicable.

Common Repair Symptoms
