Description

Overview

The Concentric Washer for SAF IO IU Air Suspension supports correct seating in suspension pivot hardware during servicing and alignment checks. Specifically, this washer uses a concentric (centred) profile, so the pivot connection can clamp consistently when the rest of the hardware is in good condition. Because trailer suspensions work hard, replacing worn washers helps maintain repeatable alignment settings and reduces the chance of movement at the pivot under load.

Features

• Concentric bore design for consistent positioning
• Supports secure clamping in pivot bolt connections
• Helps restore correct hardware stack-up during maintenance
• Compact component for quick workshop replacement

Additionally, a fresh concentric washer can help restore a stable clamp stack without changing other suspension settings.

Specifications and Materials

Part type: Concentric washer for suspension pivot hardware.

Intended system: SAF IO and IU series air suspension assemblies.

Part number: SP8750.

For general guidance on handling concentric and eccentric pivot washers, refer to the Hendrickson pivot bolt servicing guide which outlines washer seating during suspension alignment work.

Compatibility and Fitment

This Concentric Washer for SAF IO IU Air Suspension suits SAF IO and IU series air suspension hardware sets where a centred washer is specified at the pivot. Additionally, some suspension designs also use an eccentric washer in the same pivot stack for alignment adjustment, so confirm the washer type required for your build. If you are replacing hardware due to movement, then inspect mating faces, fasteners, and pivot components at the same time.

Compliance and Safety

Always support the trailer safely before working on suspension components. Moreover, tighten pivot hardware at the correct ride height and to the suspension manufacturer’s torque procedure, otherwise clamp loads can be inconsistent. Finally, replace any damaged fasteners and avoid reusing single-use alignment hardware where the OEM specifies replacement.

Trailer Applications

Commonly used on heavy trailers fitted with SAF IO and IU series air suspension systems. For example, these suspensions appear across many on-road applications, including semi-trailers and other high-duty axle groups where alignment stability matters.

Cross-reference and Suitability

No verified cross-reference or interchange part numbers were found for this item during listing research. Therefore, match by suspension series and washer type rather than relying on unconfirmed interchange claims.
