Restore firm, controlled handling on the front-left corner of your ride with the KYB Suspension Strut and Coil Spring Assembly SR4709 — a complete corner unit that arrives pre-assembled with the strut, upper mount, and coil spring ready to bolt in. It's a direct-fit front-left assembly for the 2013-2022 Buick Encore and 2015-2022 Chevrolet Trax (see the Buyer's Guide tab for engine-level fitment). A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and helps control stability, so KYB engineers this Strut-Plus unit to help restore your vehicle's original handling and control.
- OE-restoring damping: built around a KYB Excel-G strut with a stronger steel outer shell and application-specific precision damping valves.
- Application-engineered spring: a high-carbon steel coil spring matched to the strut to help maintain proper ride height and control weight without sacrificing ride quality.
- Electronic-safety aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
- Side-specific, pre-assembled: left and right part numbers with side-specific design and components, assembled for professional results.
This listing is the front-left unit; replacing struts in axle pairs is recommended for balanced ride and handling.
