Re: Quadra Lift

Its to bad they didn't cross link the front and rear. That way they could have it act like a solid axle suspension.

Re: Quadra Lift

while the system is nice, can't help but to think of BMW X5's had issues with the air suspension, many 2003-2006 Mercedes had issues with air suspension, from control modules, to leaking air, to pumps, what would make this system as reliable as a shock/spring setup available in the Limited? not to mention 1st year production, spells to me like get ready to be in the shop

There's always more risk when you're talking about a relatively complicated suspension system. You're right that there are control modules, tanks, pumps, etc. that all have the potential to fail. On the other hand, conventional coil springs are very reliable, but they do tend to droop/sag over time. Fortunately, they are easy and inexpensive to replace.

If you're really worried about reliability, just skip the air suspension and go with the coil springs instead.

Oh it will make it out sooner or later especially since this system has a higher compression than most.

Re: Quadra Lift

If you don't plan on off-roading, the springs are probably the way to go. I plan on taking my Jeep to Moab, and want the ability to raise it when I need to, without having to drive on the highway the other 99% of the time with a permanent lift that will negatively affect the handling and increase the rollover risk.

Re: Quadra Lift

Drove my 2012 Laredo X QT2 Hemi off the lot yesterday! It is fantastic-dealer trade and they gave me the chrome ltd 18s. Oversite on my part did not get the Adventure Group 2 so I dont have the QuadraLift. Am I going to miss it? Dont plan on any 4wheelin for a while as it is too expensive except for snow but last year we didnt have any-2 years before record 30" or something crazy for the south-Oklahoma City.
I like good handling better than smooth ride. Maybe I will get it when I get the 2015 diesel!

Re: Quadra Lift

Bouncy (Dolphin) ride in 2014 Laredo when towing 2.5t caravan. Does anyone know how to firm up the rear suspension? Its a Quadra Lift and I keep getting told you cant do anything to it. Can i increase the pressure? Will reducing the normal height improve firmness? Will a change to 20" wheels change things? I am in Brisbane.

Re: Quadra Lift

You could try a higher setting to firm up the bags

Do you have the proper weight on the tongue? It should be 8-10% of the loaded caravan.

Re: Quadra Lift

What Bill said...and if your caravan weighs more than about 3500 lbs, you should also be using a weight distributing hitch (WDH) to insure your vehicle stays balanced. QL alone might keep it "physically level", but it doesn't help with balance issues.

Re: Quadra Lift

Yes, I have WDH and Anti Sway Bar fitted. Ball weight at 150kg. ESC in caravan has come on about 3 times on only marginally bumpy roads. The car and van are dead flat when in sports mode or above 90km/h. I have bee toying with adding an additional water tank to the front of the van, and additional 80kg but thinks I need the car sorted first.

What is the total loaded weight of the caravan?
