Description

Overview

Levelling Valve Linkage Kit connects the levelling valve arm to the suspension linkage. It transfers ride height movement back into the valve. When the original linkage wears or bends, valve response can become erratic. This part suits BPW levelling valve service work where the linkage needs replacement without changing the full valve body.

Features

• Levelling Valve Linkage Kit for BPW levelling valve service work
• Supports clean movement between the suspension linkage and valve arm
• Helps address looseness, wear, or damaged linkage hardware
• Compact replacement part for trailer air suspension height control systems

Specifications and Materials

Use this linkage kit when the original linkage has play, damage, or missing hardware. It suits levelling valve and height control repair work on trailers with air suspension. Part number: SP0221G. For general product details on the matching WABCO linkage reference, see the official WABCO catalogue entry

Compatibility and Fitment

Match the linkage layout, arm style, and connection points before ordering. Check this closely where older repairs may have mixed different valve parts. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 02.011.50.30.0, 0201150300, 100558, WSK 64.4, WSK644, 4334010030, 433-401-003-0

Compliance and Safety

After fitting, check that the linkage moves freely through full lever travel. Also make sure all connection points are secure before the trailer returns to service. If the valve arm, bracket, clamp area, or nearby hardware is worn, fix that as well. A new linkage kit will not correct a damaged mounting point or faulty levelling valve.

Trailer Applications

This part suits trailers with air suspension levelling valves that use mechanical linkage control. It fits service work where worn linkage parts cause slow valve movement or uneven height correction. Because the linkage drives the valve arm directly, wear here can affect ride height response even when the rest of the air system still works properly.
