Description

Overview

Firestone Air Spring Assembly Hendrickson HAS helps bring Hendrickson HAS trailer suspension back to stable ride height and consistent load support. It suits service replacement when an existing air spring shows air loss, cracking, or uneven ride. Because air springs carry dynamic loads, replacing a tired unit can also help reduce chassis roll and uneven tyre wear over time.

Features

This air spring assembly targets Hendrickson HAS applications where a complete air spring replacement is preferred over reusing old hardware. It also supports workshop efficiency because you install one matched assembly rather than mixing parts.

• Direct-fit replacement for Hendrickson HAS trailer suspension
• Complete assembly format for faster service change-outs
• Helps maintain ride height and reduce vibration under load
• Supports consistent handling and reduced tyre scrub

Specifications and Materials

An air spring assembly combines a reinforced elastomer bellows with engineered end hardware so the suspension can hold pressure and flex through travel. Inspect mounts, height control linkage, and air lines during replacement so the new assembly can perform correctly.
Part number: SP0024FA.

Compliance and Safety

Depressurise the air system and support the chassis with stands so the suspension cannot drop suddenly. Follow the trailer manufacturer and Hendrickson procedures for fastener torque and air line routing, then leak-test the system after installation. Finally, confirm ride height because an incorrect setting can accelerate bellow wear.

Trailer Applications

Hendrickson HAS suspensions appear on long-haul and general freight trailers where consistent ride and durability matter. This assembly suits applications where a worn air spring causes sag, harshness, or height control hunting, especially under varying payloads.
