Will Air Lift LoadLifter 5000 Air Helper Springs Work on 2015 GMC Sierra 2500 with 3-1/2 Inch Lift

Question:

Is this air bag suspension kit compatible with a truck that’s lifted with a Rough Country 3.5” lift kit?

The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88338 should work great on your 2015 GMC Sierra 2500 but you will likely just need to add a spacer or two to accommodate for its 3-1/2 inch lift. The exact size spacer(s) you need will depend on just how much the suspension was lifted on your truck as not all 3-1/2 inch lifts are equal and a 3-1/2 inch lift does not necessarily mean that a 3-1/2 inch spacer is needed.

To determine this I have attached a helpful image that shows the upper and lower mounting points and where you will want to measure to determine the spacer height needed. Basically you will measure from the upper mounting bracket surface to the lower mounting bracket surface on your truck. Then subtract 6 inches from this number, which is the design height of the air springs included with # AL88338. The difference will be the spacer height needed.

For example if you subtract 6 from your measurement and get 2 inches, you will want to add the 2 inch Spacers # AL52420.
