Product Details

KYB Strut-Plus SR4092 is engineered as an OE-restoring suspension strut and coil spring assembly for the rear right side. KYB develops this Strut-Plus line around the vehicle’s original ride characteristics, combining a KYB Excel-G strut, a durable steel housing, and a spring selected to help return the vehicle to proper ride height and control. This part cross-references Monroe Shocks & Struts (e.g., 271662L, 371662L) for the same application. It fits 2005-2009 Buick Allure, rear right; 2005-2009 Buick LaCrosse, rear right; and 2004-2009 Chevrolet Impala, rear right.

What It Helps Address

• Rear suspension sag or uneven ride height
• Excessive bouncing, body motion, or reduced damping control
• Worn strut performance that affects steering and stability response
• Noise or harshness from a fatigued rear suspension assembly
• Ride quality changes on Buick Allure, Buick LaCrosse, or Chevrolet Impala rear right applications

Installation Notes and Tips

• Verify rear right fitment by year, model, and wheel-size notes before ordering.
• Fits 2005-2009 Buick Allure, rear right, recommended OEM replacement for vehicles with wheel sizes less than 17 inches.
• Fits 2005-2009 Buick LaCrosse, rear right, recommended OEM replacement for vehicles with wheel sizes less than 17 inches.
• Fits 2004-2009 Chevrolet Impala, rear right, recommended OEM replacement for vehicles without 17-inch or 18-inch wheels and excluding Police & Taxi models.
• Because this is a pre-assembled strut and spring unit, it is suited for professional suspension service and alignment checks after installation.
