I, like many 392 Wrangler owners, enjoy the many features of the JL Tazer Mini, one of which for this topic of discussion being Forced RWD.
I realize a lot of members drive in Forced RWD regularly and have for some time...
But does anyone know what is really going on when forcing rwd?

My understanding is that when activating Forced RWD with a Tazer Mini, the electric motor inside the transfer case, that is designed to add force to clutch pack to regulate percentage of front engagement of full-time 4 wheel drive, is now forcing to keep front drive clutches disengaged.
I have never read any discussion as to what this does to the longevity of the already known venerable electric motor inside our transferases.

Does extended use of Forced RWD over work the electric motor inside the transfercase?
What causes more stress to the electric motor, holding clutches open or forcing them together?
Are front drive clutches completely disengaged or slipping that can cause premature wear?

I would appreciate help understand what's really going on here.
 
I've looked into this long time ago and decided not to buy a Tazer JL mini to force RWD, my daily driving style just doesn't need that. Here is a video to better understand the 392 drivetrain:

Trevor also commented his thoughts on the 4wd vs rwd at the end of another video (12:40):

Last year one morning I was having some fun after turning left from a red light, a Chrysler 300C SRT next to me I believe wanted to show me his muscle, he probably wondered why a jeep wrangler made such sound and did a fast startup and maybe he was a bit irritated too. So he followed me for a second with a powerful run, all I saw in my rear mirror was he lost control and the head of the 300C shifted from the middle lane to the left then back like a snake...

I may be showing my ignorance here, but other than smoking your back tires for fun, what is the advantage of being in RWD? I know some guys love it so maybe I'm missing something. I love the feel of being planted with all 4 tires pulling.
 
Wonder if Scott Blum could help clarify?

Smoking tires is really it... I've put on a bunch of miles in both 4auto and forced rwd, with no appreciable difference in performance or economy, aside from the mentioned spinning the rear tires (provided you disabled the traction control nannies.
 
I only use it to show off. I feel like I need the AWD to safely drive it, especially in the rain.
We go to the mountains in NC every year. We used to take my wife's GC but have taken the 392 the last 3 years now bc of how well it handles the curves in the mountains in rain/snow. Ive never felt as safe in a vehicle in bad weather. It just feels planted to the pavement.

It was a good question, right up until he said transmission. My question is unanswered though. Ok, that transfer case is made to run in 2H but with Tazer and forced RWD is it the same as having it in one of the other vehicles or does it accomplish RWD differently?

This looks like Facebook. Which 392 group? I did not see it.

Very few aftermarket installers recommend the 4:1. Most say it is too low and will get away from the power of the brakes to hold. But if you are going 40s or more you should be ok.

I'd probably agree with that. First time I drove an automatic LJR I felt like I had a hard time coming to a complete stop in 4L.
 
Was there any discussion on when Tazer will support the 2024?
 
I hav never used Tazer Force RWD
i have enough toys
still burned a transfer case before 48k but i drive her hard and near daily, and nationwide since Sept 2021
when the TC did burn up and i was in 2WD RWD it was sick i drifted in the rain for a few days
that said, @justjoez was on here prior and can search.

i used to run the tazer but stopped at about 35k never looked back its in a drawer
the most use i got out of it was the tire size for speedo and dark or blackout mode when parked and trying to be a little more low key
im sure many others have made more use of the spend on it
shipping was uber fast every time
tech support was there and the turnaround is very reasonable consider its automotive in 2020s

also would flag the other participant forum input on the rear lock bypass they sell for $100?

i have no idea and part of me doubts the tazer is related to TC failures based on other theads and having tracked the issue since 2021
my first srv4wd light was well under 5k and it didnt really force the replacement until 46-47k lucky i have a service oriented dealer close with a quality powertrain tech (St Augustine CDJR)
since its my daily and i decided it will drive into the ground with me i just drove on it continued nationwide and eventually yes TC actuator test case first then the whole TC assembly google that price
covered under jeep factory powertrain no hassle
i was #66 assembly shipped of Q4 2023 said my parts dept

but i am only on this forum (vs e.g. facebook, JL forum, etc.) for my jeep so maybe a wider issue

edit
yes i see your valid question is still unanswered but i saw some new faces round these parts and thought i would rant a bit thx

one more note
on roadside the tazer can reset the srv4wd light and GET YOU MOVING again immediately with none of the issues described in many threads here
clear all codes maybe clear all DTC codes
worth it over a few .45 leigh defense rounds at a gas station outside of Atlanta. Have you seen the price of .45 ammo?
really though i travel and it happened...

by drawer mentioned above i mean the tazer jl mini is in my glove box in case the grelim returns
another appreciated christmas gift for my lady in 2023 was the "*real tazer company*" "flashlight" - check amazon

Strange with an 8 speed 3.73....I'll be in manual shift all the time...and Alcon 6 Piston Caliper Front + 4 Piston Caliper Rear...they'll hold....

Here is what I got back from them a couple days ago;



We just purchased a 2024 model wrangler 392, and the Tazer firmware is still in development.

Most of the features are working with the 11.4.4 firmware except the ones related to the Uconnect 5 radio. Turn Cam, Nav in Motion and the camera features are still in development.

I just don't have an eta at this point for full compatibility, we will make announcements on our social media channels and if you follow them, you will get the notification.
