Description

Overview

The Hendrickson 9265 Air Spring from Sampa is a complete air suspension assembly with a rubber bellows and steel lower piston for selected Hendrickson HT250T, HT250U and related trailer suspensions. It replaces compatible Firestone 9265 steel-piston and Hendrickson S-20124S configurations.

The steel-piston construction distinguishes this version from aluminium-piston alternatives. It allows replacement of the complete assembly rather than retaining the existing lower piston.

Features

• Complete air spring with rubber bellows and steel lower piston.
• Replacement for selected Hendrickson HT, HK and HS suspension configurations.
• Suitable for compatible Y-beam welded and QUIK-ALIGN suspension arrangements.
• Supplied as one complete air spring assembly.

Related Parts

The following separately available parts and configurations support servicing or alternative replacement requirements within the 9265 suspension family.

Compliance and Safety

Support the trailer securely and release suspension air pressure before removing the existing air spring. Inspect the steel piston mounting surface, retaining hardware and air connection for damage.

After fitting, restore air pressure gradually and check for leaks, correct ride height and adequate clearance during suspension movement. Follow the applicable Hendrickson installation procedure.

Trailer Applications

This assembly supports compatible Hendrickson air suspension installations on semi-trailers, including general freight trailers, refrigerated equipment, tankers and other heavy transport applications. It is particularly relevant to HT250T and HT250U suspension repairs requiring the complete steel-piston assembly.

Why Choose ICS Trailers

Replacing a Hendrickson 9265 Air Spring requires attention to the complete assembly, particularly the lower piston construction and mounting arrangement. A steel-piston replacement should be selected against the existing suspension configuration rather than relying on the general 9265 family alone.

ICS Trailers can assist with identifying the correct replacement and associated suspension hardware when repairing Hendrickson trailer air suspension systems.

• Choose the steel-piston assembly when replacing an equivalent complete steel-piston air spring.
• Send through the existing part markings, piston photos or suspension identification if you need assistance comparing replacement options.
