Rear antirock - who has it??

[chorky]

As the title suggests. Before I ended with the Rubi, i had planned on a built Sport with front and rear antirock anyway. Just tested out the sway disco on the Rubi yeaterday and it was pretty sweet. I have antirock on the front of my TJ and it makes an awesome difference. road performance is of course a little more sloppy but not by a whole lot and road imperfections are a lot smoother

however, for those with the rear antirock on your JT I am curious to hear your impressions. Please provide critical info like how much constant weight you have, or if you do mild or hard core off road, or if you still tow a light trailer, etc….

I no longer do hard core stuff but back issues leave me wanting a plush ride. Which the JRT does well. I am thinking a rear antirock with the electric discos will make for a super slick setup.

I am especially interested if anyone with rear antirock has experienced any major issues or failures. I wouldnt think so but would be good to verify.

thanks

I have front and rear anti-rock, and tried the stock electronic disconnect with the rear anti-rock for a while.

The stock disconnect + rear anti-rock doesn't change on-road driving that much, but with both installed you can feel a difference when driving on the road. It doesn't feel unsafe, but more floaty than I would want when dealing with traffic and emergency maneuvers.

With the rear sway bar, the most impressive thing is how much movement and flex I get when doing rock gardens now. It's paired with the RK Pro-X kit (triangulated 4 link), and the rear axle basically just floats around like its completely disconnected from the truck.


Requested Critical info:
- Truck is as light as I can make it, with most of the weight in suspension/wheels/steering components
- I would be afraid to tow with it
- Purpose built off-road machine

Thanks for the info!
So just to make sure I understand what your saying correctly is that

• With factory front electronic disco and rear anti-rock - road manners did not change significantly but with some increased ‘float’ off road when electronic sway is disconnected
• with anti-rock front AND rear, ‘float’ is more significant and towing/hauling would not be advisable on highway

sounds like you have a pretty sweet setup. I appreciate the input!

I would say that with the rear anti-rock, I'd also be hesitant to recommend towing anything heavy. A small trailer when going offroad would be ok, but anything more could get scary fast. The front sway bar disconnect helps keeps things a bit more controlled (reducing oversteer), but for towing you still need something to prevent the trailer from pushing your vehicle around. Imagine what is happening if all that weight pushes into an anti-rock at speed or when braking? It's going to allow the truck to flex (roll) a lot more than the stock sway bar would.

Off-road this is fine, because we want the truck to flex all over and we're going slow enough that its safe-ish. On road, not so much. Especially with a heavily loaded vehicle.

If you are just looking for more float, I'd mess with springs and shocks.

If you look at different spring and shock combinations there are a lot you can do to change the characteristics of your ride. There are many triple rate spring and floaty shock options that will take a lot of the stiffness out of the ride.

The rear antirock was designed to be very close to the stock “spring rate”. If you’re not changing the front, I wouldn’t expect a huge difference just swapping the stock rear bar for the rear antirock.

I put a front antirock on my Gladiator with about 1000 miles on the truck, so i don’t have much experience with the stock front bar. I do some hard off-roading, and ripped the stock way bar frame side links out, like many others have done. I just took the rear bar off for about six months. Including a now trip towing a trailer with 4 dirt bikes and camping gear.

After a while I added the rear antirock, mostly for higher speed stability on dirt roads. I have very little body roll now (compared to no rear sway bar ???) and the truck tends to oversteer just the right amount when turning aggressively. I love it. It handles so damn good.

I do have tuned 2.5 shocks that are probably valved stiffer than most would like, which probably adds to the stability as well.

I’d say, unless you have articulation/travel needs that the stock rear sway bar can’t handle, stick with stock. Otherwise, 100% would recommend the rear antirock.

hmm…. I thought the anti rock was at a lower rate than the factory…. Of course A bonus would be avoiding destroying the frame mounts like many have experienced.

i wonder if anyone has figured a way to install the rubi front sway disco on the rear.

I ran stock sways, no rear, no rear + discos and now front/rear AR. Run some varied but hard stuff in that I see good number of other rigs taking a pass. AR hands down beats the other combinations when it comes to having close to “no sway bar” flex and travel but way more stability.

have 100+ Lbs in the bed at any given time off road but no more than 300. Shocks and springs can firm things up to a point. I run 4.5” lift with firm reservoir shocks.

ARs made the ride feel like a snake sliding over terrain very smooth. Still getting used to it at normal speeds it feels connected to the road in a way that for me is very different. Not bad but its like I have much more feedback on everything each tire is doing. I would not call the ride “plush” but it is far from fatiguing.

Rebel Off-Road is currently working with Rock Jock on an "Overland Anti-Rock", which will hopefully be a nice compromise for folks running with more weight in the rear who want more articulation than stock. I don't know what the ETA is on them, but it sounds like it will be a great option.

this sounds like it would be perfect for what I am looking for.

Thanks for sharing. It's worth waiting for me. It sounds like a better option for daily drivers, those who tow now and then, and camping enthusiasts that stay full kit all the time.

Absolutely. If it falls somewhere between stock and a regular Anti-Rock I would be very happy.

Why not just delete the rear track bar altogether? (assuming you do a 3" lift which is the minimum required)

the most lift I would do is 2”. But thats not likely given my actual use of the vehicle. The purpose behind a looser sway bar is a more flexy (comfortable) ride when off highway.

Heads up to all. Just chatted with Rebel Off Road. The HD antilock is available and being posted up on their site soon. Not sure of the costs - didn't ask. It was even tested on one of their workers (maybe owner?) rig towing a 18' boat. Sounds like its perfect for what a lot of us are looking for. They have a front version as well for those who don't have the rubicon disco's

Will be super interested to see who goes this route and what they say as I am highly interested in it.

Part Number (rear) - RJ-256200-103

2020 sport max tow and 2” mopar lift and 35’s.
I have front and rear antirock and would highly recommend both.
- Installed e locker up front and kept the LSD in the rear for now.
- slightly more floating feel at first . Don’t notice it anymore.
- I installed the thicker front bar (.850)?
- Rarely carry loads, but had 350 in the back last week and didn’t handle any different.
- Tow a 4000 lb camper several time this summer with no issues and no weight distribution bars. It didn’t handle any different then before the antirock install.
- I don’t wheel it hard very often, but the thing is unstoppable IMO. Mostly do the Jeep jamboree’s and Jeep invasions.
