Loving select-trac!

[drjeremy78]

I have owned several AWD vehicles in the past. All had different wet weather on road characteristics. My favorite being my 1995.5 Range Rover 4.0. It was a dream to drive in heavy rain. So when I ordered my gladiator that was an option I added. For past few months the option has been sort of a $795 paperweight. Well, I finally had the chance to experience my gladiator with select-trac in heavy rain. It was very stable and did not loose traction at all. I must say money well spent!

I had the Selec-trac in my '96 and '03 Grand Cherokees. It was AWESOME in bad weather. Especially the snow. They both handled better in the snow with the 4FT than with the 4PT (IIRC, the FT was the 'all wheel drive' option and the PT was the '4x4' setting...can't remember but I do remember you had to go through the '4x4' setting to get to the 'AWD" setting... LOL). I also liked the fact that you didn't have to think about switching out of 4WD when the road went from snowy to just wet or wet plowed, then pulling back in when you hit more snow on the road...

I wished they offered this transfer case when the Gladiator first came out because I certainly would have gotten it as an option when I ordered mine back in May '19 when the ordering lines first opened up.

It's on the list of reasons I traded my 2020 for a '22. Not top of the list but it was close.

Glad to read this! There isn't much info on the Jeep website about the option and their marketing dept. should probably do something that. Stable traction on wet roads is exactly what I was hoping for when I added the option to my Gladiator.

One of the reasons I ordered was because dealers don't tend to stock SelecTrac trucks. Which is surprising in New England.

I pretty much put it on in Dec and turn it off in Mar. During the warmer months it goes on manually every time the road is wet. I could just leave it on, but I'm stupidly chasing every tenth of a mpg. Ha.

I was REALLY bummed when I discovered I could not have it with my diesel. If I could only have one of the two, I took the diesel. We had SelecTrac on our 1984 Cherokee, the very first year they made that model. We still miss that little beast even though it was woefully underpowered.

it was the only option that didnt come with my Mojave that i wanted but had to settle. I had it on my 99 Dakota and it was great only come on when needed.

Selec-trac was the main reason I traded my sport s in. That and proximity locks. My drive to work in the winter is 15 miles through farm land with half miles of snow drifts alternating with half miles of dry pavement. My only disappointment was not being able to get another manual trans with it.

 

[dcmdon]

By the way, just a clarification. In the Rubicon SelecTrac is called

Roc-Trac

They are teh same thing.

That was one of the selling points when AMC came out with Eagle and did full time bits with the viscous coupling. The Eagle especially was marketed as a family-safe vehicle on wet roads.
My Chevy had an "auto" setting on the transfer case. There was only one time I needed the get down and lock 'em all together pulling power of the manual 4 wheel mode, pulling my trailer up the hill to the neighbor's driveway in the winter, neither one of us plowed that shared drive so I really needed it all locked (it was gravel under the snow and ice)

When the roads are wet, especially after a rain that follows a long dry spell - the oils and rubber compounds on the road float up to the top making it more slippery than if it had been raining for days, I put my car in 4 wheel mode. You can feel the difference.

My drive to work in the winter is 15 miles through farm land with half miles of snow drifts alternating with half miles of dry pavement.

Similar situations here with the roads - drifts, snow, ice, then enough dry pavement you have to shift back to 2, and then suddenly ice and snow, maybe snow blew across after the storm passed.
On a 15 mile trip I might have had to shift my 2020 almost a dozen times in and out of 4H.

We've had a lot of Jeeps over the years with similar systems and when this became an option, I was upset my 2020 didn't have it.

My F250 was so bad that if you hit even 50 yards of dry pavement at any speed in 4H you could feel things bind and it was really hard to get it back into 2 wheel mode. That thing really bound up tight.

They are teh same thing.

Not the same.......
The Selec-trac is electronically controlled and can transfer 100% of torque to the wheel with traction. It's a full time mode with clutches in the transfer case.

Rock-Trac (the proper spelling) is only 4H and 4L and not automatic mode. It's also a lower low ratio.

They are different transfercases and operate differently. No comparison.



Rock-Trac

Rock-Trac is one of the most unshakeable 4x4 systems. This heavy-duty system is built to overcome the most daunting driving situations.

Some of the features in Rock-Trac include brake lock differential, Tru-Lok electronic locking differentials, electronic front sway bar disconnect, and an off-road transfer case with a 4:1 low-gear ratio. The low-gear ratio delivers the torque necessary to crawl over the toughest obstacles with a consistent speed for greater control.

 

[MoxiesDad]

The Selec-trac for the Rubicon is listed as "4:1 Rock-Trac Full Time 4WD System" on my window sticker.

It is indeed called roc-track on the rubicons:

[NachoRuby]

On the Rubicon, both the full-time and the part time systems are called rock-trac. The full-time one is simply called Rock-Trac full-time, and the standard one is Rock-Trac part-time.

Rock-trac existed before Selec-trac was an option on the JT.
The YT video clearly shows the operation of the transfer case of a Rubicon with the front and rear lockers with no automatic mode.
Rock-trac includes the low ratio and the locking differentials.
Selec-trac does not include either.
So Rock-trac on the Rubicon is not the same thing as the Selec-trac of an Overland, for example.
They are not the same thing.

Rock-trac includes low ratio, locking differentials and more
Selec-trac doesn't include either.

On the Rubicon, both the full-time and the part time systems are called rock-trac. The full-time one is simply called Rock-Trac full-time, and the standard one is Rock-Trac part-time.

Thank you, yes. They try to make it easier for people by using the same name prefix on the Rubicon as you don't want to tell them sorry, Rock-trac is no longer available - but they aren't the same.
You can't say Rock-trac in a Rubicon is the same as Selec-trac in an Overland as they are different transfer cases, and more.

Rock-trac is different and has other features. But yes, they do have an automatic option optional transfer case.
Rock-trac existed on Rubicon Wrangler and Gladiator before Selec-trac was an option on any JT.

So the owner of a 2020 Rubicon anything can't say "I have Rock-trac so I have the same thing as you have on your Overland. No, you don't.
