opened both boxes to put on tomorrow (sunday) and one of the air shocks is a completely different size. The Left hand side is smaller then the right side. Wondering if anyone who has replaced this before knows if that is how it is suppose to be or if I got sent a comfort spring instead.

The picture the OP posted looks like they are of different sizes as well and the shipping documentation verifies I did order the correct part.

Please help if anyone has knowledge on this
Judging by the pic you posted and the part numbers on each air spring, I would say it's pretty self explanatory. Obviously, they've sent you two different parts, which are not compatible with each other. Why someone would do this is questionable, but nonetheless, I'm sure Arnott's will come good.

If you notice they're so different each either, than I would return them before installation. Otherwise I hate returning package after being excited to replace the culprit old part on my car.

I am guessing they sent me one sport air spring and one comfort air spring, the mounting points on both springs are exactly what they should be for the X

Air Springs Can Leak Down VERY Slowly--Even New Ones

Perhaps some will find this info relevant...

Vehicle: 2003 X5 4.6is, 78,500 miles

Symptoms: Air suspension goes low every few days--specifically the left air spring bleeds down over several days. Air compressor would run once every few days, air spring leakage, pumps back up within one-minute run-time of compressor

Troubleshooting Approach (Phase I): Based on forum posts and Internet research concluded that left air spring most likely leaking since only one side leaks down and immediately re-inflates when air compressor kicks on.

Initial Repair: Replace both air springs with new Arnott-brand from rockauto.com. ($250 total)

Initial Results: right air spring--holds air and works as-new; left air spring--leaks air immediately after install, going completely flat within 8 hours. Left spring pumps up normally each time but leaks down within hours after vehicle parked.

Troubleshooting Approach (Phase II): Swapped left and right lines, reservoirs, solenoids until everything from left side was on right side and vice-versa (with the obvious exception of the solenoid connectors which must remain on their respective sides in order to insure correct leveling is maintained). No change in behavior--therefore, conclude that brand-new Arnott air-spring on left side is defective.

Secondary Repair: Replace new left-side air spring with ANOTHER new left-side air spring.

Secondary Results: All good, no more leak down.

Conclusion: Even a brand-new air spring can be defective. It was especially disconcerting because the defective air spring was on the same side as the failing original air spring. Conclusive diagnoses was reached only after swapping all components--except springs--from left to right and observing that the left air spring was still leaking down even though it was connected using all components from the right side (except solenoid wire connections).

Secondary Conclusion: I would find it difficult to recommend Arnott air springs for any application given their inability to produce 100% reliable new components. But perhaps another brand would be no better.

There must be something about left air springs. When I had my E39 540i Touring M Sport. I had a failing right rear air spring. I purchased a left and right sport spring set from BMW and upon installation the system worked but after a couple of days the left side went down. Now I never had a problem with the left side. We deduced that the new left air spring was defective. I returned it for another new left and upon installation all was well. So I think its just safe to say that you can get defective components from the OE and aftermarket. Cost cutting in the parts market is taking its toll. On another note my X5 had the rear air springs changed out with the previous owner and they are arnott units. They work fine on my X5. I don't think you will find a better aftermarket and at least their warranty gives some piece of mind.

If anyone is looking for a DIY for the front struts, I just completed one and it's now up on YouTube. Here's the link:

Do you guys mostly have 2-corner (rear) or 4-corner (front + rear) air?

I am pretty sure rear was standard equipment in the 4.4 cars and 4 corner was optional or came in the nicer trim packages?
