KYB 5550013 Suspension Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Transit

The KYB Gas-a-just 5550013 is a rear suspension shock absorber for select Ford Transit vans with a short wheel base. It is built as an OE-style monotube replacement to restore original ride control, with responsive damping for daily driving and added performance when road conditions demand it.

Key Features

• Monotube shock absorber design for consistent rear suspension control
• Two working chambers: an air-free hydraulic piston and valve area plus a high-pressure nitrogen gas chamber
• Floating piston separates gas and hydraulic sections for stable operation
• Compressed length: 16.57 in; extended length: 25.71 in; stroke length: 9.14 in
• Lower mount type: E2(12x48); upper mount type: E2(14x80)
• Dust cover included
• Part number: 5550013

Detailed Description

KYB Gas-a-just shocks are engineered for drivers who want the rear suspension to respond predictably under load changes, braking, and uneven pavement. On the Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD, part number 5550013 replaces the rear shock with a monotube design that separates hydraulic and gas chambers for controlled damping and quick response. This KYB Gas-a-just 5550013 is a direct-fit rear shock absorber for 2015-2024 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD short wheel base applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Vehicle Fitment

• Fits 2015-2024 Ford Transit-150, rear, (SWB) Short Wheel Base; Gas-a-just
• Fits 2015-2024 Ford Transit-250, rear, (SWB) Short Wheel Base; Gas-a-just
• Fits 2015-2024 Ford Transit-350, rear, (SWB) Short Wheel Base; Gas-a-just
• Fits 2015-2024 Ford Transit-350 HD, rear, (SWB) Short Wheel Base; Gas-a-just

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control from worn rear shock absorbers
• Unstable ride quality in loaded or empty driving conditions
• Rear-end harshness caused by aging suspension damping
• Uneven handling response on Ford Transit vans

Installation Notes and Tips

Verify rear mounting style and dimensions before installation: compressed length 16.57 in, extended length 25.71 in, and stroke length 9.14 in. Confirm the vehicle is a short wheel base Ford Transit-150, Transit-250, Transit-350, or Transit-350 HD with rear shock fitment before ordering. Replace shocks in pairs on the same axle when service history and wear patterns indicate both sides have aged similarly.

Quality Assurance

KYB positions Gas-a-just as an OE monotube replacement line, using a hydraulic piston and high-pressure nitrogen gas chamber to support consistent damping response. Part number 5550013 is built for the rear suspension of select Ford Transit models and includes a dust cover.
