KYB 551610 Suspension Strut - Rear

KYB Gas-a-Just Rear Strut for Jaguar S-Type

KYB Gas-a-Just 551610 is a rear suspension strut built as an OE-style monotube replacement for the 2000-2002 Jaguar S-Type. It is engineered to restore original control and handling while delivering quick response for vehicles that carry load, tow, or run larger wheels and tires.

The Gas-a-Just line uses a high-pressure monotube design with separate gas and oil chambers for consistent damping and immediate reaction to suspension movement. For Jaguar S-Type rear suspension service, part number 551610 provides a direct-fit replacement focused on ride control, steering response, and reduced fade under demanding driving conditions.

Detailed Description

KYB Gas-a-Just 551610 is a rear suspension strut for the 2000-2002 Jaguar S-Type, including recommended OEM replacement applications up to VIN M45254 and excluding adaptive control suspension. The monotube design uses an air-free hydraulic working area for control and a separate high-pressure nitrogen gas chamber for consistent performance. This setup is suited to drivers who want firmer response and stable damping from a rear strut replacement.

KYB’s Gas-a-Just product line is built for OE replacement use where original suspension behavior matters, while also adding the quick response associated with high-pressure monotube construction. Part number 551610 is a practical choice when servicing rear suspension on the Jaguar S-Type and when restoring predictable ride quality is a priority. This part cross-references Monroe Shocks & Struts 71367 for the same application.

What It Helps Address

• Rear suspension bounce or reduced damping control
• Excessive body movement during braking, cornering, or lane changes
• Delayed steering response from worn rear struts
• Ride inconsistency caused by aging monotube suspension components
• Seal wear and fluid leakage associated with strut failure

Installation Notes and Tips

Verify vehicle fitment by year, model, and VIN before installation. This strut fits 2000-2002 Jaguar S-Type, rear, with the noted VIN and suspension restrictions. KYB recommends replacing strut mounts at the same time to reduce noise and vibration; for this application, KYB lists mount part number SM5549. Inspect related suspension components, fasteners, and alignment settings during service.

Quality Assurance

KYB is an OE suspension supplier, and the Gas-a-Just line is built as a monotube replacement to match the vehicle’s original suspension design intent. Part number 551610 is engineered for consistent damping, responsive control, and dependable rear suspension service on the Jaguar S-Type.
