Rear Helper Springs for a 2007 Chevy Suburban 1500 with Factory Auto-Leveling System

Question

Question:

I see in your QandA section that this Air Spring is supposed to fit a 2007 Suburban 1500. My question is will it still fit if the vehicle is equipped with the factory Autoride suspension? I like the idea of a having a little extra help with the springs in case the air shocks go down for any reason...

I do have a solution for you but air springs such as # F4108 will not fit on a 2007 Chevy Suburban 1500 that has the factory auto-leveling option. What I recommend is to use Timbren helper springs # TGMRYS4 that fit in place of the factory bump stops because they won't interfere with the factory auto-leveling system.

I have linked a video showing an example installation and a link to our informational article on Timbren springs for you to view.

It is possible that the trailer is simply too large for a 1/2 ton SUV. The weight is borderline of what I would be comfortable towing with a 1/2 ton, but the length I think is a bigger concern. That is an awfully long trailer not to be use a 3/4 or 1…

A properly rated weight distribution that is set up correctly should eliminate the sag you are experiencing on your 2009 Chevy Suburban. It is possible that the spring bars on your EAZ Lift system are rated too low and thus cannot eliminate the sag.…

The handle is actually the on/off switch for the unit and the bolt under the handle is the tension adjustment bolt. You will need to turn the On/Off handle clockwise (tighter) until the handle will stay firmly in place parallel with the main body of…

Answer 10

For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle…

Answer 11

Since you have a wheelbase/axle spacing of 38 inches the correct hanger kit for slipper springs would be the part #HAP-105-205-01. And then for a 7k trailer axle the u-bolt kit you'd want would be the part #APUBR-8. I attached the diagram to use…

Answer 12

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…
