1. Arnott Air Suspension A-2738 Air Suspension Airspring
This unit earned its spot on my list because of its dependable rear axle support. It provides the heavy duty structure needed to prevent sag under load.
In my view, you get reliable OE level performance without paying dealership overhead. The main limitation is that it only covers the back end, so you still need separate front repairs.
Buyers frequently mention that this air spring restores factory ride height immediately.
Reviewers appreciate the straightforward design that matches original mounting points.
A few notes point out that installation requires basic mechanical patience.

2. Arnott P-2936 Air Suspension Components
Do-it-yourself mechanics tackling a failing pump will find this kit suits their repair style best. It targets the internal mechanical wear that usually kills an aging unit.
I rank this high for anyone wanting to save repair costs instead of buying an entirely new assembly. You do need to possess some technical confidence to install the internal components correctly.
Users note that the replacement rings and seals fix pressure leaks effectively.
Customer feedback highlights the value compared to a full compressor swap.

3. Arnott Industries Air Suspension Spring – A-3891
A clever internal dampening layer catches your attention first on this specific spring. From there, the design expands into a sturdy solution for the driver side.
I consider this the smart targeted fix when only one corner of your suspension fails. The downside is potential uneven aging if your right side spring is equally worn.
Drivers state that this part cures side to side vehicle lean.
Feedback confirms the rubber bladder thickness matches factory durability.
Some buyers note you should inspect your air lines while performing this swap.

4. Arnott Industries Air Suspension Spring – A-3892
The most frequent buyer complaint centers on the single side replacement nature of this spring. People often wish it came in pairs to balance out wear schedules.
I still think it serves as a practical passenger side solution if you have localized damage. You just need to accept that matching the left side later might be necessary.
Owners report that the mounting brackets align precisely with factory studs.
Reviewers mention a noticeable drop in cabin vibration after installation.
Common feedback warns against replacing only one side if mileage is very high.

Buyers consistently report fast inflation times upon initial startup.
Reviewers note that the integrated dryer helps prevent moisture damage.
The primary caution involves ensuring your electrical relay is also replaced.

Choosing Between Them
If you need complete system repairs, my top recommendation is the Arnott Air Suspension Compressor. For targeted fixes, you should look at the Arnott Left Air Spring or the Arnott Right Air Spring depending on your failing side. Drivers focusing on the back end will prefer the Arnott Rear Air Spring, while handy owners can choose the Arnott Compressor Rebuild Kit.
Keep in mind that production locations for these components span multiple global facilities. You should always double check your specific vehicle manufacturing origin and part numbers before ordering.
