Question: Would a max tow package ride quality suffer??

[ShadowsPapa]

First test drive I took was a Sport S with max tow. I ended up with an Overland, but frankly the Sport S with max tow is what sold me on how well these things rode and drove. Very nice, IMO.

I also put max tow REAR springs under the REAR of my Overland - to keep it from sagging so darned badly with a load or with my trailer hooked up. It's a bit more firm but IMO that was the SHOCKS I put on it. The best part - my wife hasn't commented on it being any different.

Its common knowledge that the Max Tow Rear springs are progressive. Here are some pictures for you. Count the number of coils & look at the spacing.

And this is one of my OEM Max tow springs sitting in my garrage.

The difference in springs does not come with the Max Tow, they are listed on my sticker as part of the S package. According to my sticker my max tow has Normal Duty Plus Suspension which is listed as being part of the S package. I would assume that the base sport has just has normal duty suspension not the plus but it does not mention the suspension for the base model.

My Max Tow sport rode fantastic stock. Comfortable and responsive. I did not buy it to tow with though. WIth the Mopar 2 inch lift it still rides great (but those factory springs are gone).

Based on the window sticker the Max Tow must also have the same fenders since the fenders are not mentioned right? That extra lip must be everyone just imaging it...

The lip is real, the hell with the sticker. At least on my 20.

Just like the progressive springs to handle that extra load.

progressive springs don’t handle the extra load. The standard spring spacing Handles the same load. The tighter spacing that’s in the progressive springs gives it a bit of a soft ride. that’s why the max tow or the sport s, which ever one has progressive springs, is a nicer ride.

the more horizontal the coil, the softer it is, the more vertical and spaced out the coil, the harder it is. This doesn’t account for coil thickness though. That will also effect how easy the spring compresses.

“Progressive rate springs” are generally classified into two sub-types: 1) constantly increasing rate springs and 2) a “dual-rate” spring with two linear rates connected with a rate-transition range.

The first type (constantly increasing rate) of springs are most often used as “load-compensating springs” on the rear of a vehicle when the vehicle will often see significant load changes in the cargo area. These are most often stock replacement type suspension springs. They are identified most easily by continually varied spacing between the coils.

So I don’t know if you were trying to explain the science behind it, but progressive rate springs are indeed used for the heavier load.

Max tow is a beast, rides awesome.

The Sport S pckage springs bdnshocks are different parts, each with there own part number, same with the shocks. I had my dealer parts person look this up, when I ordered the MaxTow springs for my Soet S. The MaxTow springs were physically longer than the Sport S springs on my Sport S sticker listed heavy duty suspension springs. The ride is also a little different, when driving the Spirt S without a load. Also, the MaxTow springs kept the back of my Soirt S from dropping more than an 1-inch with a heavy fire wood load. The same load with the stock Sport S springs, the rear dropped about 2-inches.

He Soirt S has heavy duty springs, the MaxTow sori gs are progressive, giving a softer ride unloaded and then they get stiffer as weight is added, providing more support to the truck suspension.

No (the max tow does not ride poorly or really any different than the other models).

I'm not a professional driver but when I test drove (every model one right after another) I would have ranked ride quality:

1) Mojave
2) Sport with max tow
3) Overland
4) Sport
5) Rubicon

That said they all rode great and were marginally different IMO.

So what I said is still correct. The spring gets stiffer as it’s coil gets more vertical. A progressive spring is used to handle heavier loads because if they used a linear spring it would be very stiff, when there is no load. It’s progressive so it has some give when there is no load in the back.

If you look at the two coils photographed in this thread, the stock one only has one less coil. The extra coil in the progressive spring will give that section of progression a lower spring rate, making it softer.

I can’t tell from the photos, but if the progressive coil is thicker, then it will be a stiffer spring. But being a progressive spring doesn’t mean it’s stiffer or can handle more load, it just means it isn’t linear.

I’ve only drove my Rubicon. Now your making me want to try the other trims. Was the rubicon the stiffest ride?

 

[TrailHiker]

Yes, the MT progressive coil is a little thicker.
cheers.

It felt stiffer and more top heavy to me. That said I got a max tow sport and immediately put rubi springs in the front with rubi shocks all around and a 3/4 leveling kit on ... so now my max tow rides almost exactly like what I ranked last lol. Again difference was extremely marginal and it looks so much better
