Re: Quadra Lift ride Quality

So, after EXHAUSTIVELY checking the parts lists and actual vehicles...this is what I've come up with in terms of suspensions (HA vs standard Overland). I checked a variety of HA VINs as well as ones for the standard Overland.

2015 Overland and High Altitude [4x4 only]

There's no part difference. Both have the exact same [SDA] coded air suspension parts (shocks, air springs, air spring/shock combo). Here are the parts used for both:

Front air spring/shocks (North American version only):
68231883AA (left, [SDA])
68231882AA (right, [SDA])

Rear Air Springs:
68029912AE (both sides, [ALL])

Rear Shocks:
68234049AB (both sides, [SDA])

Now, here's the kicker. There IS a difference in the 4x2 models (which aren't air suspension equipped). The 4x2 Overland gets the [SDA] coded standard springs and shocks (SDA = normal duty suspension). The 4x2 High Altitude gets the [SDE] coded shocks and springs.

The way it is: 4x4 Overland and High Altitude have the exact same air suspension. There's no "sport" air suspension factory installed on the 4x4 High Altitudes vs a standard Overland that I've come across. The 4x2 version of the High Altitude DOES get sport-coded suspension parts (4x2 doesn't have get

2016 Overland and High Altitude

Same thing. 4x4 air suspensions are identical between the High Altitude and standard Overland. 4x2 standard suspensions DO have a difference between them.

Front air spring/shocks (North American version only):
68253205AD (left, [SDA])
68253204AC (right, [SDA])

Rear Air Springs:
68258355AB (left, [ALL])
68258354AB (right, [ALL])

Rear Shocks:
68298960AA (both sides, [SDA])

As you can see, the 2016-2017 part numbers for the air suspension components have changed across the board, so there IS a slight difference between the 2014-2015 and 2016-2016 air suspensions (but not between the HA and Overland for either category).

Re: Quadra Lift ride Quality

Peter,

Can there be different programming? I'm not suggesting there is, just wondering if you think it is a possibility.

Re: Quadra Lift ride Quality

I can't speak for the part numbers, I can only speak for the way it feels. The 16 HA (at least) rides/handles differently than my 14 Overland did. That difference feels more substantial than just the change in tires from Fortera to Ecopia, even though that has some effect.

2017 Summit has the same change.

hmm my guess on that is that when they moved from the super soft fortera which was a rotten tire but was a soft smooth cruiser to the more quality Ecopia/Verde which are slightly stiffer tires they tried to compensate a bit by dropping the pressure a little so people didn't note a possibly stiffer ride.

So the HA literature is missing the caveat (sport tunned suspension 4x2 models only)? sounds similar to them promising people leather center console lids and then delivering vinyl which made people run back to get the leather ones on the HA for a period of time. parts databases can have typos but since you validated it on real vehicles it is what it is I guess.

I don't think it's the tire change. Because typically that recommendation applies to all tires that meet the spec.

I've seen other cars change it with no change in hardware.

I've seen cars that are the same Chasis, motor, tires and suspension under different "brands" have wildly different recommendations.

It could be braking, mpg, ride, handling or marketing.

Sure would be nice to know the source though so we can decide and understand the trade offs. I like to run mine a few pounds high. But am I compromising traction control in slippery conditions?

What pressure are they targeting when the tire warms up? How can the recomendation be the same for Florida and Alaska? On average the pressure will be vastly different using same cold pressure. Depends a lot where you drive too what average temp tire will see.

Re: Quadra Lift ride Quality

Thanks for that Peter_K

I wonder if 2012 4x4 Overland had different suspension parts than 2015 or if it's just going from a hemi to a pentastar making the very obvious difference in ride quality I've experienced.

Re: Quadra Lift ride Quality

I'm pretty sure the QL system was updated for MY '14. It seems to be more reliable since then. That may exhibit some changes in suspension feel.
