Product Details

KYB’s Strut-Plus line is built as a complete suspension strut and coil spring assembly for vehicles that rely on the front strut to carry load, control ride height, and influence steering feel. For the Buick Encore and Chevrolet Trax, this assembly pairs KYB’s OE-restoring strut design with a coil spring selected to match the vehicle’s weight distribution and corner loading. The result is a service part aimed at restoring original ride height and front-end control on the left side.
