Overview

KYB Gas-a-just 5510041 is a monotube suspension strut built as an OE-style replacement for restoring original ride control and response. It is made for the front left position on the 2004 Subaru Impreza and uses a two-chamber design that separates hydraulic action from high-pressure nitrogen gas for consistent damping.

Key Features

  • Monotube strut design for responsive suspension control.
  • Air-free hydraulic chamber for steady damping performance.
  • High-pressure nitrogen gas chamber with floating piston for added ride comfort and quick response.
  • OE monotube replacement construction for direct service use.
  • Part number 5510041 for easy identification.

Detailed Description

The KYB Gas-a-just line is engineered for drivers who want a strut that matches the original monotube layout while restoring control characteristics. On the 2004 Subaru Impreza, front left fitment is confirmed, and the 5510041 strut uses separate working chambers to balance normal-road comfort with firmer response when suspension demand increases. This design helps maintain consistent damping behavior during everyday driving while supporting sharper handling feedback when conditions change.

This part cross-references Subaru OE numbers 20311FE211 and 20311FE310 for the same application.

What It Is Used For

  • Restoring worn suspension damping.
  • Reducing excessive bounce after bumps.
  • Improving steering response and road control.
  • Replacing a leaking or weak front strut.

Installation Notes and Tips

Fits 2004 Subaru Impreza, front left. Verify compressed length, extended length, stroke length, and upper mount thread size before installation. Confirm the mounting orientation and inspect related suspension components for wear during replacement. Part number 5510041 should be matched to the vehicle application before service.

Quality Assurance

KYB Gas-a-just struts are built as OE monotube replacements and follow the brand's suspension engineering focus for consistent control and ride quality.
