Key Features

• Monotube OEM replacement strut for direct suspension service
• High-pressure gas and oil separation for consistent damping response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response and suspension control
• Supports vehicle systems that rely on factory suspension behavior
• Rear right fitment for 2005-2007 Subaru Impreza

Product Details

KYB Gas-a-just part number 5510029 uses a two-chamber monotube design with an air-free hydraulic working area and a separate high-pressure nitrogen gas chamber. That layout helps maintain fade-resistant operation, responsive damping, and a comfortable ride during everyday driving. For Subaru Impreza owners, this strut is a fitment-specific solution for the rear right position and is listed for 2005-2007 models. This part cross-references Subaru 20360 FE902 for the same application.

The Gas-a-just line is KYB’s monotube performance-oriented OE replacement family. It is built for drivers who want factory-correct suspension geometry and predictable control without changing the vehicle’s original design intent. If you are searching for a KYB 5510029 rear right strut for a 2005-2007 Subaru Impreza, this part matches that application.

Common Problems This Strut Can Address

• Excessive bouncing or poor rebound control
• Fluid leakage from a worn strut assembly
• Reduced steering response and loose handling feel
• Uneven ride quality at the rear suspension
• Loss of factory-like control on the Subaru Impreza rear right corner
