rear sway bar recommendations

-
none...put a wider rear tire on it. Put a rear sway bar on an a body and you'll understeer badly...maybe right off the road at highway speeds on tighter curves. Check the tiny sway bars on modern vehicles like big trucks.

I respect your opinion but I have a front sway bar , and think it would help for the rear , I run 55's on rear , I have front rear sway bars on my ebody and it handles great but if the consensus is not to add I will do more research an may not add

surely you mean oversteer correct?

also, agree. because of the design of mopar leafs, and the inherently stiff, short front section many cars don't need a rear bar and it could in fact be detrimental to handling depending on the rest of the set up.
 
Have a 72 duster with 8 3/4 rear , what's the best sway bar recommendations for this car ?
i would suggest a smaller diameter bar-- something between 1/2~5/8 depending on the rest of the set up.

rear bars can be an excellent addition and great for tuning the suspension package for optimum performance. but like everything too much can be a bad thing in the grand scheme of things.

i don't like bars that mount to the axle, but sometimes that's unavoidable due to limitations of the chassis, exhaust, etc.

that said, if i was buying right now i'd probably hit up firmfeel for a bar.

I did replace the leaf springs with espo springs when I added the 8 3/4 , I like the 5/8 suggestion , might be way to go , I bought a FF steering box stage 3 , will ask them there recommendation as well
 
Best investment I've made is Bilstien all around and bigger torsion bars.

And I already had sway bars, QA1, Espo springs.

I have looked at the Bilstein shocks , and may end up buying a set for both my cars , I have them on my truck and they are great
 
I have front and rear Helwig swaybars on both my cars . Corners like a champ even with little tires . One of the best upgrades I’ve ever made.
 
And my 69 Swinger is a 525 hp stroker with a 4sp . It launches super straight! Never wanders in the rear .

I ran one, & for a while, w/o the front one......with the over-assisted PS, what fun it was to hang onto...loose as a goose!!! Once I put the 1.125" frt. F-M-J bar I adapted back on with a better mounting system, w/the .870" T-bars, home-stacked 6-leaf rears, & the 3/4" F-M-J rear bar.....that thing stuck like glue. I could run down My neighbor's IROC-Z through the twisties fast enough to ram it & wreck it,..lololol...

What torsion bars do you have up front? Is it a factory front seat bar or aftermarket? How are you using the car and what tires are you running?

I run front and rear sway bars on my Duster, my rear bar is actually a larger, 7/8” e-body Hellwig.

The important thing is that you’re adding the sway bar to balance the car. The whole deal about A-bodies not needing them is complete garbage, but it does depend on how the car is set up with the rest of the suspension and tires.

Factory cars are all set up to understeer. It’s easier to drive like that and requires less skill. Having a car that’s on the edge of oversteer is faster for handling, but requires more driver skill to manage. If your car understeers, a rear sway bar will improve that. If you’re already into oversteer, well, a rear bar will make that worse.

The Hellwigs have 3 holes to adjust. They say to use the center hole 1st and adjust. Also links are connected in a better way to the frame.
That's what I was going to recommend as well.

It appears that you are sorely mistaken in your understanding of vehicle dynamics.
 
take this for what it is worth. A leaf spring car does not have a rear sway bar. It is a stabilizer bar. Like the front it transfers weight from one side to the other and stabilizes the car to keep it level. Sway bars are usually seen on a coil spring car with control arms and are connected to the sides of the lower control arms to prevent the rear from moving side to side and also weight transfer. I had sway bars on my Chevelles and GTO's I had stabilizers on mopars.

Rear stabilizers on mopars were not that helpful as were the fronts. Good for cars with a lot of rear cargo weight and weak springs. I tried them and the seamed to give the car more understeer or push entering turns at high speeds. They do look cool . I would recommend good bushings that would stop spring roll. In the past we replaced all the bushings with aluminum and kept them lubed but they were noisy and didn't last long.

Been there with the stabilizer and it looked cool but didn't keep it long when I decided bigger was better

340 stock torsion bars and a factory front sway bar I removed from a 73 and installed on my 72 when converting to disk brakes , running 15 inch tires P255 60R on rear P215 65R on front

I will add , I have not driven the car just yet , its the car I am building and its ready to drive but haven't painted just yet , and I like rear bar on my ebody and was debating on whether to add on my present Duster before hitting the road , its going to mainly a driver but I want it driving properly as I am in rural area , lots of winding roads in areas as well , and who doesn't like to pass slow Ford or Chevy from time to time , Hellwig does look like the better bar although Firm Feel might be an option , so to Bar or not to Bar , that is the question
 
From lots and lots of reading, it seems if you run heavy sway bars or stabilizer bars, you don't need heavy torsion bars, as they somewhat emulate sway bars in a way and heavy torsion bars coupled with heavy sway bars usually isn't a good idea. At least that's what I understand.
 
ma mopar would disagree with you there...

I am not Ma Mopar

When you look up either they both come up with the same replacement parts.

To me a sway bar stops the sway of back and forth of side to side movement of the body to suspension. A stabilizer bar transfer the load from one side to the other. Push one side down and the other is pulled down by the stabilizer bar end links. Stabilizing body roll. not body sway. I call them by what they do.

Coil spring cars have rear sway bars. The have no end links, They attach firmly to the side of the control arms and stop side movement of the angled arms and roll. Mopars have end links that do not stop side movement of the rear at all only body roll.

You always have to find something to start an issue . Why don't you just explain the definition from the dictionary in the difference of the words used as you did in the past. I don't care what mopar calls them only their purpose. Look up either and you get the same parts.
