Question:

So with the 5000 kit, would you choose the kit with the international bump stops ? Think it was the kit 5000 ultimate, maybe. Also I measured the rear lift blocks on my truck and they are only a 3 inch lift in the rear. So I'm assuming I only need a 3 inch air bag spacer, not a 6 inch spacer. Any good 3 inch spacer you would recommend ?

Yes, the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57538 will work on your 2015 GMC Sierra 2500. However, you don't need to use the 7500 XL system nor would I advise it. Instead, I recommend the Air Lift LoadLifter 5000 Air Helper Springs part # AL57338. The 7,500 lb and 5,000 lb weight capacity you see is for pin/tongue weight, not gross trailer weight as the the pin/tongue weight is the only part that is directly over the top of the airbags. They will however both do an excellent job of reducing the rear end sag while towing but the 7500 XL system may be a bit too stiff.

In order to allow for either set of airbags to mount on the truck, you will need to use a spacer since it has been lifted. The correct height of spacer for you usually equates to the height of the suspension lift only. For example, if you have a true 6" suspension lift then odds are you are going to need the Lift Spacers part # F2374.

The Air Lift LoadLifter 5000 Ultimate Air Helper Springs part # AL88338 have an internal jounce bumper that is going to allow for a load to be carried with no air in the airbags. This is a good feature but the decreased ride quality is not worth the seldom used benefit in my opinion so I still recommend the Air Lift LoadLifter 5000 Air Helper Springs part # AL57338. If you only have a 3" tall lift blocks in the rear then you are correct that a lift spacer like the Lift Spacers part # F2368 should be all that you need. However, once you get the upper and lower brackets installed you can measure the distance between them and if you get 8.5" to 9.5" then this will be the perfect spacer for you.
