Arnott VB-4334 Air Suspension Solenoid Valve Unit - Rear

Arnott VB-4334 Air Suspension Valve Block

Arnott VB-4334 is a direct replacement air suspension solenoid valve block for the rear compressor valve block on select Land Rover Discovery models. It is built with quality O-rings and electrical components to restore proper air distribution from the compressor to the air struts or air springs.

Fits 1999-2004 Land Rover Discovery, rear compressor valve block.

Key Features

• Direct replacement for the vehicle’s failing air suspension valve block
• Specific fit for rear compressor valve block applications
• Pin terminal type with 3 terminals
• 2 square connectors and 3 ports
• Female connector design for OE-style integration
• Standard grade construction for suspension service
• Part number VB-4334 for easy identification

Detailed Description

The Arnott VB-4334 solenoid valve unit is designed for Land Rover Discovery air suspension systems that rely on a rear compressor valve block to route air to the suspension. Over time, valve block O-rings can dry out and leak, which can cause the compressor to run more often than normal. Moisture intrusion can also affect the electrical solenoid components and lead to additional air suspension faults. This replacement valve block is built to meet or exceed original equipment expectations using durable sealing materials and electrical parts.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application. Use VB-4334 when servicing a 1999-2004 Land Rover Discovery rear air suspension valve block and you need a direct-fit replacement that matches the original system layout.

What It Helps Fix

• Air leaks at the valve block caused by worn O-rings
• Compressor overwork from repeated pressure loss
• Slow or uneven air delivery to the air springs or air struts
• Electrical solenoid issues caused by moisture exposure
• Rear suspension height control problems on Land Rover Discovery models

Installation Notes and Tips

Verify connector shape, terminal count, and port layout before installation. Inspect the air lines, compressor output, and surrounding suspension components for contamination or damage before replacing the valve block. After installation, clear any stored air suspension fault codes and confirm the system builds and holds pressure correctly. VB-4334 is a specific-fit part for the listed Land Rover Discovery rear compressor valve block application.

Quality Assurance

Arnott manufactures this valve block with OE-level materials and component quality to support reliable air suspension operation. The design is intended to match the original system function and restore proper air routing in the rear suspension circuit.
