Product Details

The KYB Strut-Plus line is built around KYB’s OE-restoring strut design and application-specific spring tuning. For front suspension service on the 2004-2012 Chevrolet Colorado and 2004-2012 GMC Canyon, as well as 2006 Isuzu i-280 and 2007-2008 Isuzu i-290, SR4279 provides a direct replacement solution for restoring front-end control, ride height, and steering feel. This part cross-references Monroe Shocks & Struts (e.g., 171353, 181353) for the same application.

What It Helps Address

• Excessive front-end bounce or poor damping response
• Uneven or lowered ride height from worn spring and strut components
• Noisy, loose, or unstable front suspension behavior
• Reduced steering precision during braking and cornering
• Front suspension wear that can affect ESC and ABS system performance

Installation Notes and Tips
