Question:

Hi Would the F4150 fits on my 2011 qx56 rear suspension? If not would u have any recommendation? I am not really towing but the truck sags at the rear suspension and I can use the helper to return it to its original height What would be the best psi pressure to use? Your help is greatly appreciated Thanks

The Firestone Coil-Rite Air Helper Springs # F4150 is designed to fit inside the rear coil spring of an Infiniti QX56 from 2004 to 2010 as long as they are not equipped with an Auto-Leveling Suspension system. From what I could find out, the 2011 model year of QX56 all came with this style of leveling system.

With that being said, the only upgrade we have for your vehicle will be the Stability Plus Stabilizer Helper Springs # SPS97FR that is designed to attach to rear factory leaf springs.
