Description

Overview

The Firestone trailer air spring restores load support and controlled suspension movement on compatible Neway, Reyco and Ridewell trailer suspension systems. This rolling-lobe assembly replaces the complete airbag rather than the rubber bellows alone. Correct identification depends on the air spring markings, mounting arrangement, air inlet position and operating dimensions.

Features

• Complete rolling-lobe air spring assembly
• Suits compatible Neway, Reyco and Ridewell suspension applications
• Maximum operating pressure of 7 bar or 100 psi
• Operating temperature range from -40°C to +70°C

Specifications and Materials

The assembly combines a reinforced rubber bellows, metal upper bead plate and lower piston with integral mounting points. It is supplied as one complete air spring assembly for replacement of the corresponding suspension unit. Part number: SP0013FA.

See the official Firestone air spring replacement guide

Compatibility and Fitment

Check the identification markings on the removed air spring before ordering. Compare the upper mounting plate, piston profile, stud positions, mounting centres, air inlet thread and location, compressed height and extended height. The same bellows family can be assembled with different plates and pistons, so the bellows shape alone is not enough to confirm fitment.

Compliance and Safety

Support the trailer securely and exhaust all suspension air before removing the existing assembly. Inspect the mounting faces, studs, air line and fitting for corrosion, damage or thread wear. Do not exceed the specified maximum operating pressure. Inflate the suspension gradually after installation and check for leaks, bellows rubbing and correct clearance throughout the suspension travel.

Trailer Applications

This assembly suits matching Neway, Reyco and Ridewell trailer air suspension systems. Workshops should use the old air spring number wherever it remains legible and compare the physical mounting arrangement before installation. Particular attention should be given to the upper plate pattern and air connection because similar rolling-lobe airbags can use different port and stud layouts.

Why Choose ICS Trailers

Air springs can be difficult to identify after the label has faded or the original assembly has been replaced. Send through the old part markings, clear photos, mounting centres, plate dimensions and air inlet position when you need help narrowing down the match.
