KYB 5510032 Suspension Strut - Rear Left

KYB Gas-a-Just Rear Left Strut for Subaru Impreza

The KYB Gas-a-Just 5510032 is a monotube suspension strut built as an OE-style replacement for the rear left position on the 2004 Subaru Impreza. It is engineered to restore original handling response, steering feel, and suspension control for drivers replacing a worn rear strut on a Subaru Impreza.

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 supports quicker steering response
• Designed to help maintain the performance of vehicle safety systems that rely on suspension control
• Rear left application for 2004 Subaru Impreza

Product Details

KYB Gas-a-Just struts use a two-chamber monotube design with an air-free hydraulic working area and a separate high-pressure nitrogen gas chamber. That layout supports responsive damping during normal driving while providing firmer control when suspension demand increases. Part number 5510032 is a fitment-specific rear left strut for the 2004 Subaru Impreza, and it is intended to replace the original monotube-style unit while helping restore the vehicle’s designed ride and handling balance. This part cross-references Subaru 20360FE711 and 20360FE850 for the same application.

What It Helps Address

• Excessive bouncing or poor rebound control from a worn rear strut
• Fluid leakage caused by seal wear
• Reduced steering response and loose handling feel
• Uneven ride quality at the rear suspension
• Loss of suspension control that can affect braking and stability system performance

Installation Notes and Tips

Fits 2004 Subaru Impreza, rear left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify upper mount type S1 (12MM) and confirm compressed length, extended length, and stroke length before installation. Part number 5510032 should be matched to the vehicle’s rear left suspension position and original equipment configuration.
