Product Details

KYB Strut-Plus SR4236 is part of the Strut-Plus line, a complete suspension solution built around KYB’s OE-restoring strut design. For the Ford Focus, front left, this assembly combines damping control and spring rate tuning to help return the vehicle to factory-style ride height and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 272258, 282258) for the same application.

Compatible with 2008-2011 Ford Focus, front left, this assembly is a direct-fit replacement for the suspension strut and coil spring assembly specified by the manufacturer. The KYB Strut-Plus SR4236 is designed for drivers and technicians who need a pre-assembled front left strut solution for Ford Focus suspension service.

What It Helps Address

• Front-end sag or uneven ride height
• Excessive bounce, sway, or reduced damping control
• Clunking or worn strut assembly symptoms
• Steering instability caused by a fatigued strut and spring assembly
• Ride quality changes after suspension wear on a Ford Focus

Installation Notes and Tips

Install on the front left position only and follow the vehicle manufacturer’s instructions for strut and coil spring replacement. Verify side-specific fitment before installation, and confirm that the replacement matches the original suspension configuration on 2008-2011 Ford Focus models.

Quality Assurance

KYB supplies original equipment components and builds the Strut-Plus line to restore handling, control, and ride height to OE specifications. The SR4236 uses KYB’s OE-restoring strut design and application-specific damping calibration to support consistent suspension performance.
