Arnott VB-3790 Air Suspension Solenoid Valve Unit

Arnott VB-3790 Air Suspension Valve Block

The Arnott VB-3790 is a direct replacement air suspension solenoid valve block for vehicles with a failing valve unit. Built with quality O-rings and electrical components, it is designed to meet or exceed original equipment standards for consistent air distribution in the suspension system.

Compatible with 2008-2022 Toyota Sequoia applications, this valve block helps restore proper airflow from the compressor to the air struts or air springs. It is a specific-fit replacement for Toyota Sequoia air suspension systems that need accurate valve control and leak resistance.

Key Features

• Direct replacement air suspension solenoid valve block
• Specific fit for Toyota Sequoia applications
• Blade terminal type with 3 terminals
• Female square connector with 1 connector
• 3-port design with 6 mm outside diameter ports
• 2 mounting holes for vehicle-specific installation
• Built with quality O-rings and electrical components
• Designed to meet or exceed OE specifications

Detailed Description

The Arnott VB-3790 air suspension solenoid valve unit controls how compressed air is routed through the suspension system. In Toyota Sequoia models, the valve block plays a key role in sending air from the compressor to the air struts or air springs, helping maintain proper ride height and suspension response. Over time, worn O-rings can dry out and leak, while moisture exposure can damage the solenoid electronics and create additional system faults. This replacement valve block is engineered to address those common failure points with OE-style fitment and materials.

This part cross-references Toyota (e.g., 4809634010) for the same application.

Common Problems It Can Help Solve

• Air leaks caused by dried or worn valve block O-rings
• Compressor overwork from loss of system pressure
• Slow or inconsistent air suspension height changes
• Electrical solenoid issues caused by moisture intrusion
• Faulty air routing between the compressor and air springs

Installation Notes and Tips

Fits 2008-2022 Toyota Sequoia, N/A. Confirm connector shape, terminal count, port layout, and mounting points before installation. Inspect the surrounding air lines, fittings, and compressor operation so the new valve block is not installed into a system with unresolved leaks or electrical damage.

Quality Assurance

Arnott manufactures this valve block to meet or exceed original equipment requirements using quality sealing and electrical components. The VB-3790 is built as a direct replacement for the factory valve unit in Toyota Sequoia air suspension systems.
