Neway suspensions
Neway is the suspension brand covered in the SAF-HOLLAND manufacturer references linked here. AD and ADZ are drive-axle air-suspension families for vocational truck and tractor work. Their similar names do not make their control arrangements, ratings or service parts interchangeable. Establish the installed model and approved application before comparing a vehicle or planning a replacement. A suspension rating is only one part of a complete chassis assessment.
Compare the model families
| Model / family | Application | Overview | Model notes |

| AD | Vocational drive-axle air suspension | Neway AD is a drive-axle air-ride suspension listed by SAF-HOLLAND for severe vocational use. Its parallelogram arrangement uses conventional torque and track rods, and the manufacturer lists single, tandem and tridem configurations. It is a distinct design from ADZ. | In this guide |
| ADZ | Vocational drive-axle air suspension | Neway ADZ is SAF-HOLLAND’s vocational drive-axle air suspension. The manufacturer describes a V-rod upper control arrangement and a one-piece lower control assembly, with single, tandem and tridem options. These design details distinguish it from the Neway AD family. | In this guide |
Bring the exact specification.
The family name helps organize your search. The build sheet, serial number and relevant manufacturer documentation identify what is installed. Compare like-for-like applications and request evidence for cost or performance claims.

AD

Source checkpoint:
Neway AD is a drive-axle air-ride suspension listed by SAF-HOLLAND for severe vocational use. Its parallelogram arrangement uses conventional torque and track rods, and the manufacturer lists single, tandem and tridem configurations. It is a distinct design from ADZ.
Scope North American model family; equipment and availability vary by model year and configuration.
AD identification includes the axle connection
SAF-HOLLAND describes AD with conventional torque and track rods, and either bar-pin or optional thru-bolt axle connections. Its published capacity is up to 30,000 lb per axle, with single, tandem and tridem arrangements. The phrase “up to” describes the family’s published ceiling, not the rating of every installed AD.
Make a parts request more precise than “Neway air ride”
If a used-truck file contains only a generic Neway description, obtain the suspension identification before accepting a parts estimate. Ask the supplier to state which AD axle-connection version the estimate covers. Record the installed per-axle rating separately from the number of axles, rather than multiplying the family’s maximum and treating the result as a vehicle rating. This is a useful document check when comparing trucks with similar bodies but different chassis specifications. The connection style is an identification detail, not permission to substitute a different mounting arrangement.
What matters in a comparison
For a Neway AD truck, collect the complete suspension identification, axle arrangement and ride-height specification. Compare those records with the installed body and intended work. Off-highway approval in product literature does not authorize any load or body combination. A qualified chassis assessment should consider the whole vehicle before a change in duty or equipment is made.
Questions to take to the supplier
- Which AD configuration is installed?
- What ride height and body application were approved?
- Does the proposed work match the original specification?

ADZ
Vocational drive-axle air suspension
Source checkpoint:
Neway ADZ is SAF-HOLLAND’s vocational drive-axle air suspension. The manufacturer describes a V-rod upper control arrangement and a one-piece lower control assembly, with single, tandem and tridem options. These design details distinguish it from the Neway AD family.
Scope North American model family; equipment and availability vary by model year and configuration.
The control-arm layout distinguishes ADZ
ADZ uses a one-piece lower control-arm assembly and upper V-rods in place of the conventional torque and track rods described for AD. SAF-HOLLAND lists 23,000 or 26,000 lb per axle and weld-on or bolt-on axle adapters. These are configuration choices within ADZ, not proof that AD and ADZ parts interchange.
Read an ADZ quotation as an assembly description
When two estimates use the same ADZ name, ask each supplier to identify the axle-adapter version and the installed suspension assembly to which the quoted components belong. Keep that information beside the truck’s build record. A lower price is not a like-for-like comparison if one quote covers a different connection or leaves out associated hardware. For a prospective vehicle purchase, use the same approach to distinguish an installed configuration from a sales brochure’s options. An available higher per-axle rating does not authorize uprating the truck.
What matters in a comparison
An ADZ comparison should retain the exact model, rating and installation details. Ask for the correct application documentation and parts reference instead of assuming AD components fit ADZ. Evaluate the complete chassis and body when discussing stability or carrying capability. Published suspension claims do not establish the condition of a used truck or replace an inspection of its actual installation.
Questions to take to the supplier
- What ADZ model and axle count are fitted?
- Does the parts reference match the control-arm arrangement?
- Is the body and chassis application documented?
