Description

Overview

The Freightliner 9781 Air Spring from Sampa is a complete air suspension assembly with an aluminium piston and included mounting bracket. It suits selected Freightliner truck suspension applications requiring the bracket-equipped 9781 configuration.

Unlike the standard bracketless version, this assembly includes the mounting bracket as part of the supplied unit. This distinction matters when replacing an air spring with damaged mounting components or when the existing bracket cannot be reused.

Features

• Complete air spring assembly with aluminium lower piston.
• Mounting bracket included with the air spring.
• Replacement for compatible Freightliner 9781 suspension configurations.
• Rubber bellows construction for pneumatic suspension support.

Compatibility and Fitment

This assembly suits selected Freightliner truck suspensions requiring an aluminium-piston air spring with an attached mounting bracket.

Before ordering, compare the original bracket shape, mounting positions, air inlet and piston arrangement. The bracketless 9781 version belongs to the same air spring family but does not provide the complete mounting configuration supplied with this assembly.

The following cross-reference numbers identify verified equivalent or replacement parts for this exact application. Confirm the selection-critical fitment details against the part being replaced before fitting.

Related Parts

The following separately available components and related versions support servicing of the Freightliner air suspension arrangement.

Compliance and Safety

Support the vehicle securely and release suspension air pressure before removing the existing air spring. Inspect the mounting bracket location, fasteners, surrounding structure and air connection for damage.

After installation, restore air pressure gradually and check for leaks, bracket security and clearance throughout suspension movement. Follow the applicable Freightliner suspension installation procedure.

Trailer Applications

This air spring supports compatible Freightliner prime mover suspension systems used in articulated transport operations, including vehicles towing semi-trailers and other heavy commercial equipment.

The bracket-equipped assembly allows replacement of the air spring and associated mounting bracket together, rather than transferring the existing bracket onto a bracketless unit.

Why Choose ICS Trailers

Freightliner 9781 air springs are available in different piston and mounting configurations. When replacing the complete assembly, the bracket arrangement is particularly important because the wrong version may require additional mounting components or may not suit the original installation.

ICS Trailers can assist with comparing the existing air spring, aluminium piston and bracket arrangement against the required replacement. If the original bracket remains serviceable, the separate bracketless version may also be worth considering.

• Choose this assembly when both the air spring and matching mounting bracket require replacement.
• Send through the existing air spring markings, bracket photos and mounting measurements if you need assistance identifying the correct configuration.
