Product Line Details

KYB Strut-Plus is the brand’s complete strut assembly line for restoring suspension geometry, ride height, and steering response in one service part. The SR4128 follows that approach with an OE-restoring KYB strut and a high-carbon steel coil spring selected for the vehicle’s corner weight and suspension requirements.

Detailed Description

KYB, an original equipment supplier, engineers the SR4128 to match the ride and control characteristics expected from the factory suspension. The assembly is built for 2003-2005 Honda Civic front right and 2002-2003 Acura EL front right applications, making it a direct solution for drivers replacing a worn strut and spring assembly on the passenger side front corner. This part number, SR4128, is designed to restore ride height within OE specifications while maintaining stable steering feel and consistent damping performance.

This part cross-references Monroe Shocks & Struts (e.g., 172185, 182185) for the same application.

Common Problems It Can Address

• Front-end bounce or excessive body movement over bumps
• Uneven ride height at the front right corner
• Noisy or worn suspension strut and spring assembly
• Reduced steering stability during braking or cornering
• Suspension wear that affects ESC, ABS, or related system behavior

Installation Notes and Tips

Install on the front right position only. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions, and verify that the vehicle is supported safely before removal. Because this is a pre-assembled unit, it is intended to simplify service and reduce the need to transfer spring components during installation.

Quality Assurance

KYB manufactures this Strut-Plus assembly as an OE-focused replacement part and assembles it in the USA. The design uses application-specific damping and vehicle-matched spring rates to help restore factory-style suspension performance on compatible Honda Civic and Acura EL models.
