Arnott K-4365 Air Suspension Pressure Valve - Front

Arnott K-4365 Pressure Retention Valve

The Arnott K-4365 is a brass pressure retention valve (PRV) for air suspension strut assemblies. It helps keep a preset amount of air pressure in the strut during service and after installation, reducing the risk of air spring damage from improper inflation or pressure loss.

Compatible with select Jaguar XJ8, XJR, Vanden Plas, Super V8, and XJ8 front strut applications, this PRV is a practical repair for aging air suspension systems. The Arnott K-4365 is also referenced by OE-style interchange numbers for the same application.

Key Features

• Pressure retention valve (PRV) for air suspension struts
• Brass construction for serviceable durability
• Male-to-male metric connections
• Helps retain preset air pressure during shipping and installation
• Restores function when older valves are corroded or restricted
• Fits front strut applications on select Jaguar models

Detailed Description

Arnott K-4365 is an air suspension pressure valve used at the strut to maintain pressure in the system when needed. By holding a preset air charge, it supports safer handling of the strut assembly and helps protect the air spring from damage caused by improper inflation procedures, compressor failure, compromised air lines, or valve block leaks. This makes it a direct-fit repair choice for front air strut service on Jaguar XJ8, XJR, Vanden Plas, Super V8, and related applications.

This part cross-references OE-style numbers such as C2C2244 and C2C2245 for the same application. If you are servicing an aging Jaguar air suspension system and the original valve is corroded, stuck, or no longer sealing correctly, the Arnott K-4365 provides a straightforward replacement path.

What It Helps Fix

• Front air strut that will not hold pressure
• Corroded or seized pressure retention valve
• Air spring damage from improper inflation during service
• Pressure loss caused by compressor failure
• Pressure loss related to compromised air lines or valve block leaks

Installation Notes and Tips

• Use on front strut applications listed for 2004-2009 Jaguar XJ8, 2004-2008 Jaguar XJR, 2004-2009 Jaguar Vanden Plas, and 2005-2009 Jaguar Super V8.
• Confirm the existing valve style and connection type before installation.
• Inspect the strut, air line, compressor, and valve block for leaks before returning the vehicle to service.
• Follow the vehicle service procedure for depressurizing and re-pressurizing the air suspension system.

Quality Assurance

Arnott manufactures air suspension components for service and replacement applications, and the K-4365 is built as a regular-grade brass PRV for direct repair use in supported Jaguar front strut systems.
