KYB SR4116 Shock Absorber - Rear

KYB Strut-Plus SR4116 Rear Suspension Assembly

KYB Strut-Plus SR4116 is a rear suspension shock absorber assembly engineered to restore ride height, handling response, and vehicle control on select Buick, Cadillac, Pontiac, and Oldsmobile applications. Built around KYB’s OE-restoring approach, this assembly is designed for vehicles that rely on precise rear suspension performance and stable ride characteristics.

Key Features

• Includes a KYB Excel-G strut with application-specific damping valves
• Uses a stronger steel outer shell for added structural support
• High carbon steel coil spring is matched to vehicle attributes and corner weights to help restore OE ride height
• Assembled in the USA
• Exact-fit, pre-assembled design for professional installation results
• Engineered to help vehicles with electronic safety systems such as ESC and ABS
• KYB Strut-Plus SR4116 is built for rear suspension applications that require controlled ride and stable handling

Product Details

KYB developed the Strut-Plus line to address the full role of a strut assembly, including supporting vehicle weight, maintaining ride height, acting as a steering pivot where applicable, and helping preserve stability. For rear applications such as the Buick Lucerne, Buick LeSabre, Cadillac DeVille, Pontiac Bonneville, and Oldsmobile Aurora, SR4116 is engineered to restore original suspension behavior with OE-style fitment and damping characteristics. This part number is a practical choice when the goal is to return the rear suspension to factory-like control without changing the vehicle’s intended ride profile. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Vehicle Fitment

What It Helps Address

• Rear-end sagging or loss of ride height
• Excessive bounce, float, or reduced damping control
• Uneven rear suspension response on Buick Lucerne, Buick LeSabre, Cadillac DeVille, Pontiac Bonneville, and Oldsmobile Aurora applications
• Handling instability caused by worn rear shock and spring components
• Suspension performance issues that can affect electronic stability systems

Installation Notes

Verify rear fitment by year, make, model, and suspension configuration before installation. SR4116 is application-specific for rear use and includes notes for systems such as Magnetic Ride Control, Electronic Suspension, and Self Leveling Rear, so matching the vehicle’s original equipment setup is essential. Because this is a pre-assembled Strut-Plus unit, installation is typically more straightforward than rebuilding individual suspension components, but professional installation is recommended for proper alignment and suspension performance.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling, control, and ride height to OE specifications. SR4116 is assembled in the USA and built with OE-focused damping and spring selection for consistent rear suspension performance.
