Description

Overview

Air Spring Assembly CS9 Left-Hand Side is the left-hand air bag assembly for applicable ROR/Meritor CS9 trailer air suspension systems. Part number SP0110 is specifically the left-hand side assembly and should not be substituted with the right-hand SP0106 unit.

A leaking, fatigued or damaged air spring can affect trailer ride height and suspension response. Replacing the complete assembly helps restore correct load support and allows the air suspension to operate through its intended range of movement.

Features

• Left-hand side only CS9 air spring assembly
• Part number SP0110
• Complete air spring and piston assembly
• Designed for ROR/Meritor CS9 trailer air suspension applications
• Helps restore correct ride height and suspension response
• Heavy-duty replacement for trailer suspension service and repair

Specifications and Materials

SP0110 is a complete CS9 left-hand air spring assembly designed to carry suspension load using compressed air while allowing movement through normal suspension travel.

• Part number: SP0110
• Position: Left-hand side only
• Suspension application: ROR/Meritor CS9
• Compressed height: 209mm
• Extended height: 565mm
• Maximum diameter: 300mm
• Piston width: 262mm
• Mounting threads: M12x1.5 and 2 x M12x1.75

Always compare the dimensions, mounting arrangement and position of the existing air spring before installation.

Compatibility and Fitment

SP0110 is the left-hand side only CS9 assembly. If the trailer requires the right-hand CS9 assembly, use SP0106 instead.

The ROR/Meritor CS9 air spring family is commonly associated with reference numbers including Meritor/ROR 21229214 and Firestone W01-M58-8608 / 1T17DJ-7. These numbers are useful when identifying the CS9 air spring application, but they should not be used by themselves to determine whether the complete SP0110 left-hand assembly or SP0106 right-hand assembly is required.

Confirm the side of the trailer, existing mounting arrangement and original assembly before ordering.

Compliance and Safety

Air suspension components can remain under pressure and the suspension may move suddenly when air is released. Support the trailer correctly and fully depressurise the suspension before removing the existing air spring.

Inspect the mounting surfaces, brackets, fasteners and air lines for damage before installation. Fit and tighten components to the suspension manufacturer’s specifications, reconnect the air supply and check carefully for leaks.

After inflation, confirm the air spring sits correctly at normal ride height and has adequate clearance from surrounding chassis and suspension components throughout normal suspension travel.

Trailer Applications

SP0110 is designed for the left-hand position on applicable ROR/Meritor CS9 trailer air suspension systems.

CS9 suspension systems are used across a range of heavy trailer applications. Fitment should therefore be confirmed from the suspension and existing air spring assembly rather than relying on trailer body style alone.

Cross-reference and Identification

The following references are associated with the ROR/Meritor CS9 air spring application and may assist with identification:

Important fitment note: The reference numbers above identify the CS9 air spring family and do not by themselves identify the side-specific complete assembly. SP0110 is the left-hand side assembly. SP0106 is the right-hand side assembly. Confirm which side is required before ordering.
