Overview

KYB Gas-a-just part number 5550035 is a rear suspension shock absorber built as a monotube OE-style replacement and performance upgrade. It is engineered for direct fitment on select Ford Edge and Lincoln Nautilus applications, with responsive damping for everyday driving and added control when conditions demand it.

Key Features

• Monotube shock absorber design for consistent damping response.
• Gas-a-just line combines hydraulic control with high-pressure nitrogen gas.
• Rear shock absorber application for select Ford Edge and Lincoln Nautilus models.
• Upper and lower mount dimensions are specified for fitment accuracy.
• KYB part number 5550035 for easy identification and ordering.

Detailed Description

The KYB Gas-a-just line is positioned as an OE monotube replacement for the Ford Edge Sport and Lincoln Nautilus, and as an upgrade for other Edge trims. Its two-chamber construction separates the hydraulic working area from the gas chamber, helping the shock respond quickly while maintaining ride comfort during normal use. For shoppers comparing rear shock absorber options for a Ford Edge or Lincoln Nautilus, part number 5550035 provides a fitment-specific solution with the mounting and length specifications needed for the listed applications.

This part cross-references Ford and Lincoln OE numbers (e.g., F2GZ18125N, K2GZ18125AJ) for the same application.

What It Is Used For

• Restoring rear suspension damping performance.
• Reducing excessive bounce after bumps or dips.
• Improving control during load transfer and cornering.
• Replacing a worn monotube rear shock absorber.
• Addressing ride instability caused by weak or leaking shocks.

Installation Notes and Tips

Fits 2015-2024 Ford Edge, rear. Fits 2020-2023 Lincoln Nautilus, rear, without electronic controlled suspension. Verify compressed length, extended length, stroke, and mount style against the original shock before installation. Part number 5550035 should be matched to the vehicle’s suspension configuration and notes for correct application.

Quality Assurance

KYB is known for OE-level suspension engineering, and the Gas-a-just line is built around a monotube design with separate hydraulic and gas chambers for controlled response.
