• Built with quality O-rings and electrical components
• Standard-grade replacement for reservoir and rear applications

Detailed Description

The Arnott VB-3505 valve block is engineered to replace a failing air suspension solenoid valve block in select Land Rover vehicles. It regulates airflow from the compressor to the suspension circuit, which is critical for maintaining correct ride height and system response. This part number VB-3505 is built to meet or exceed original equipment expectations using durable sealing materials and electrical components that address common wear points in the factory unit. This part cross-references URO (e.g., RVH000046, RVH500070) for the same application.

Compatible With 2005-2009 Land Rover LR3, Reservoir; 2006-2013 Land Rover Range Rover Sport, Reservoir; 2006-2012 Land Rover Range Rover, Rear; 2010-2016 Land Rover LR4, Reservoir. Common search terms include Land Rover LR4 air suspension valve block replacement, Range Rover Sport reservoir valve block, and Range Rover rear air suspension solenoid valve unit.

What It Helps Fix

• Air leaks caused by dried or damaged valve block O-rings
• Compressor overwork from pressure loss in the suspension circuit
• Moisture-related electrical solenoid problems inside the valve block
• Slow or inconsistent air delivery to the air springs or air struts
• Suspension height control issues tied to valve block failure

Installation Notes

Verify connector style, terminal count, and port layout before installation. This VB-3505 uses a specific-fit design with 2 female square connectors, pin terminals, and 4 ports. Inspect the air lines, fittings, and electrical connectors for contamination or damage before installing the replacement valve block. Confirm the vehicle application by model year and suspension position: reservoir or rear.

Quality Assurance

Arnott manufactures this air suspension solenoid valve block with materials selected to match OE-level function and durability. The design focuses on sealing integrity and electrical reliability for Land Rover LR3, LR4, Range Rover Sport, and Range Rover air suspension systems.
