Detailed Description

KYB Strut-Plus SR4220 is designed as a complete suspension strut and coil spring assembly for the front left corner. It is built to help restore original ride height and handling characteristics on 2005-2010 Kia Sportage and 2005-2009 Hyundai Tucson applications. The KYB Strut-Plus line focuses on OE restoration, using a KYB strut, precision damping valves, and a spring matched to the vehicle’s weight and suspension geometry. This part number, SR4220, is a direct-fit solution for drivers and technicians looking for a front left strut assembly for Kia Sportage or Hyundai Tucson service work.

This part cross-references Monroe Shocks & Struts (e.g., 172220) for the same application.

What It Helps Address

• Excessive bouncing or poor damping response
• Uneven or sagging front ride height
• Loose steering feel at the front left corner

Installation Notes and Tips

Fits 2005-2010 Kia Sportage, front left. Fits 2005-2009 Hyundai Tucson, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify side-specific fitment before installation, since SR4220 is engineered for the front left position only. Because this assembly is pre-assembled, it is intended to streamline professional suspension service while maintaining OE-style fitment.
