Product Details

KYB Strut-Plus SR4154 combines a KYB OE-restoring strut with a coil spring engineered around the vehicle’s weight and suspension geometry. As a suspension strut and coil spring assembly, it helps return the front suspension to proper ride height and handling balance while maintaining the steering pivot function built into the strut design. This part is a strong match for drivers searching for a front right strut assembly for 2007-2010 Toyota Sienna, especially 8 passenger seating models that need a direct replacement with side-specific fitment. This part cross-references Monroe Shocks & Struts (e.g., 172365, 172980) for the same application.

What It Helps Address

• Front-end sag or uneven ride height
• Excessive bounce, body roll, or loose handling
• Noisy or worn original strut and spring components
• Steering response that feels less precise than stock
• Suspension wear that can affect ESC, ABS, and related systems
