Shock/Strut Each

The KYB SR4279 Strut-Plus shock absorber is a direct replacement front strut assembly engineered for GM light trucks from 2004 to 2012. This single-unit strut combines the damper and spring support into one sealed cartridge, delivering responsive suspension control for models including the Silverado, Sierra, and Colorado platforms. The twin-tube design separates the working and reserve fluid chambers, providing consistent damping force over extended use cycles.

Built with steel construction and finished in black paint, this strut is sized to fit the factory mounting points without modification. The twin-tube architecture is the industry standard for light-duty suspension work—it isolates the main working piston from aeration that occurs during sharp compressions and rebound, which extends damping performance and reduces fade under repetitive loading. At 15.53 pounds and measuring 9 by 8 by 26 inches, the unit installs as a bolt-for-bolt replacement for worn OEM struts. The sealed design minimizes maintenance and delivers predictable handling characteristics whether you're towing light loads or managing highway miles.

This strut is ideal for owners seeking to restore factory suspension performance without the cost of complete frame-off rebuilds. Worn struts cause excessive nose-dive under braking, reduced body control during turns, and uneven tire wear—issues that the SR4279 directly addresses. Technicians and DIY rebuilders commonly use KYB Strut-Plus units for fleet maintenance, trade-in reconditioning, and off-road truck refreshes where reliability and predictable behavior matter more than aftermarket tuning.

KYB is a tier-one OEM supplier whose components equip millions of factory vehicles globally. The Strut-Plus line sits between budget sealed units and premium adjustable platforms, offering engineering-proven durability and factory-matched response curves at a practical price point for owners who value consistent suspension behavior over custom tuning options.
