Description

Overview

Air Spring Assembly MP7 Meritor FS Suspension helps maintain stable ride height on Meritor FS air suspension by supporting consistent load and damping road shock. It suits fleets and owner drivers replacing a leaking or fatigued air spring where air loss can cause uneven tyre wear and a harsh ride. Fitting the correct assembly can also help protect suspension bushes and hardware from repeated bottoming.

Features

• Supports controlled chassis height under changing loads
• Helps reduce vibration transfer into the trailer and prime mover
• Designed for air suspension service in heavy vehicle applications
• Operates within common heavy vehicle air system pressure limits

Compatibility and Fitment

Confirm mounting style and air inlet type against the vehicle or suspension documentation before installation. 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. 1T15MPW-7, 1T15MPW7, W01-358-6262, W013586262, 21227742 FS25, 21227742FS25, 90557233.

Compliance and Safety

Depressurise the air system before removal, then refit using suitable lifting and isolation practices. Inspect the air lines, push-to-connect fittings, and height control valve linkage since a new air spring will not fix upstream leakage. After installation, perform a leak test with soapy water and recheck fasteners after the first service interval.

Trailer Applications

This assembly is commonly used where MP7 configurations run Meritor FS suspension on heavy vehicle and trailer combinations. Fitment can vary by axle group and bracket arrangement, so match the mounting points and air port layout to the existing unit. If you are replacing Air Spring Assembly MP7 Meritor FS Suspension to fix sag or lean, check for worn linkages or valve faults before blaming the air spring.
