The AirLift springs are not particularly difficult to install. They would install inside of your coil springs.

A helper spring kit like the AirLift # AL60769 you referenced is primarily designed to help suspend cargo stored in the cargo area of your Suburban, not to compensate for tongue weight applied to the hitch.

For your situation, a Weight Distribution kit would be my recommended choice for leveling your Suburban. In order to choose the right system for your trailer's tongue weight, you'll need the exact tongue weight which includes the weight of anything you stow in the cargo area of the Suburban behind its rear axle, whether it be coolers, camping gear, the Mother-in-Law, whatever. I've linked you to an article that explains how to determine this.

For a tongue weight of 800 lbs, I would recommend the Reese Steadi-Flex W/D kit, part # RP66560. This system is effective on trailers with tongue weights ranging from 600-1200 lbs. Since boat trailers typically have a pole or straight tongue, you will also need a pole tongue adapter, part # RP58393.

I have linked you to an FAQ article that will further explain how weight distribution systems work.

Answer 5

You would want to hitch your trailer up to your tow vehicle and then inflate the bags of the Air Lift Kit part #AL60769 to the point where the vehicle is leveled. So to long story short...inflate the bags after hitching up.

I actually have a much better solution for your 2008 GMC Yukon XL. Suspension enhancement will give the rear suspension more support when towing, but a weight distribution system is actually the better solution. Not only will it give your rear…

Answer 7

It sounds like the purpose of getting the air helper spring would be to counteract the 1 inch compression you're getting in your rear suspension caused by the pin weight of your 5th wheel. If that's the case, I believe that the AirLift 5000…
