Adding a rear sway bar to a truck for towing. How hard? Is it worth it?

Considering that Truck Norris will be hauling my CJ around, I am looking at ways to improve the towing capabilities in general. I've already got the J20 axles (mostly) installed so I have the better brakes. I'm also going to be adding a trailer brake controller. One of the things I'm considering is adding a rear swaybar.

Has anyone done this? What are the pros and cons? I can't imagine it's very hard to accomplish. What sorts of problems am I likely to run into?

Any insight into this would be appreciated.

Theres plenty of room to do it and Id think another bar (J20 front) would mount up easily. Or you could get one from a 1 ton in the salvage yard but those OEM one are small in comparison to the front sway bars. Good luc and post up pictures.

Rear sway bar

ADDCO makes a rear sway bar for J Trucks.

I plan on installing when I spring over lift my J20.

I have a rear sway bar on my 74.
Unfortunately that jeeps springs are shot, so I can not tell if they do any good?
I think I will install it on my 76, as I am also installing a front sway bar on it.

Long range goal is to tow a classic trailer.

You should take some pic's of that Dusty.

I figure since I got one on an older rig up front with all that stuff in the way the rear should not be too hard. I think I still have the bar that was on my original 14-Bolt.

I do not know what brand it is or anything, as it was on this poor thing when I bought it. I will have to look at the geometry of it when I install it on my waggy with the 4" lift.

do u really think it's needed? sway bars are made to control body roll. hopefully u wouldn't be experiencing body roll when towing. i would instead stiffen up the rear springs. when u stiffen up the rear, u are also helping to reduce body roll automatically. combine big springs with a good load leveling hitch & rock on down the highway.

I agree. If these were coil sprung rigs it'd be a no brainer, but with leafs it's overkill from everything I've read. Asphaltrockdweller-You need to put the sawzall to that nasty trackbar when you install your lift.

The lift is already on, and the 1976 Wagoneers did not have track bars.

Even with good stiff springs, whilst driving on the street/highway, sway bars do help control your vehicle. My other 76 Z code has a front sway bar with a 4" lift, and the difference is amazing.

So yes! I will try to install this on to my everyday jeep.

I will have to look under the Dodge and see what they use. Maybe you could adapt a newer design.

Thanks for the pic's Dusty.

I look at it this way:
When I am towing, even my small trailer (maybe 900lbs fully loaded to Ouray) and go into a turn and have to brake, it pushes one side down in the rear and the other side comes up. It's not terrible, but it's noticeable.

Granted I'm SOA (home-fab front sway install with disconnects) and longer 63" GM springs in back, so it's probably more pronounced than a rig with stiffer lift springs or even stock.
I'd figure out some type of disconnect in the rear for once I am on the trail, but I want the best stability I can get on the highway with something pushing me while braking.

Gotcha. I saw the endlinks on those pics and it looked more like a track bar instead of a sway bar. I've put disco's on all the front swaybars in Jeeps I've owned. With the 4" Rusty's lift on my '82, I've left them disconnected. I haul boats, etc. a good bit and can't imagine needing a rear sway bar. But that's just my 2 cents. In Tad's case, with SOA, I absolutely get it.

The rear sway bar is a good topic. I've thought about one for mine. I see a lot of late model leaf spring trucks with rear sway bars. The OEM's try to save all the money they can- if the sway bar didn't help I'm sure they wouldn't bother.

I bet if you had a rear sway bar and one of those air bag assist kits it'd be one mean tow rig

Why are you breaking in a turn? You're supposed to accelerate into a curve!

That's my long term goal.

Finish it off with a nice turbo charged 4BT and it'll be just about perfect.

With a sway bar you can minimize the effects of roll etc without having to suffer with stiff springs when not loaded or towing.

The rear bar will really help when the wind is a blowin. I put some hellwig sway bars on my 1 ton chevy work van back in the 90's (upgraded front, added rear along with some koni red shocks). Put it all on but they sent me the wrong rear bar. When I put the rear bar on later, the difference was instant and very noticeable.

Cool, I had seen these back in the day in JC Whitney catalog but never seen one installed. With longer links from the swaybar to the frame, it should work fine on a lifted Waggy.
