QuadraLift reliability

I have quadralift and getting new tires put on today. 275/55 R20s look flat out mean. Just went with the Falkin Wild Peak A/Ts. Look amazing and from what we can tell there are no rubbing issues. Time will tell but heading off-road I'd just up the ride height.

With the tires off I was just looking at the air suspension and it still blows my mind seeing it. Anyone know to what standard they build these things? How they are tested? What's the reliability like and if I hook a 23ft Pathfinder boat up am I ask risk of blowing one?

Re: QuadraLift reliability

mate you have the best suspension for towing you will not ever blow one. the suspension is designed to always self level not like normal spring suspension where it sags, yours will inflate and deflate to suit the load applied via a leveling valve.

Re: QuadraLift reliability

I've had air suspension on each of my last three SUVs. When you read forums, you always see talk of failed air suspension components and it rests in the back of your mind as a high failure item. I have a 23' center console that weighs between 5200-5800 lbs. depending on how I have it loaded, with tongue weight being at about 10%. I have not had any issues with any air suspension, but that obviously does not mean problems do not occasionally pop up. I do have the opinion the more a component is used, the higher likelihood of failure but that is true with anything. Just use it and worry about a problem when a problem actually develops; some that never use their Quadralift beyond what the car automatically does will have failures, while those that use it all the time in offroading and load leveling may never encounter an issue. Luck of the draw, IMO.

Re: QuadraLift reliability

air suspensions have been around for years, i work on them daily in the heavy transport industry. the only failures are the complex computer systems that control some of them. components where out just like any other suspension.

Re: QuadraLift reliability

While there are certainly higher incidents of issues with tech like QL than without--that's simply a factor of being more complex and having more opportunities for "Mr Murphy" to enjoy some "fun", it's not something new to the automotive world nor to Jeep. Jeep has built tens of thousands of JGC with QL and most customers haven't had issues. Many of us do choose to purchase the Mopar MaxCare Extended Service Contract to protect against the real risk of issues with all the technical complexity in today's vehicles, especially beyond the 3/36 OEM warranty period, however...

And the above comment about QL being ideal for towing is spot on. QL doesn't take away the need for a WDH for heavier loads to properly balance things over the axils, but it does make for a nice, self-leveling situation while towing that's very good to have.
