Installing Suspension Techniques
Swaybars On Your First Generation Neon

Last Updated 9/03/03
I have a first generation "Highline" Neon. This car came with a
20mm front swaybar and no rear bar. R/T, ACR, and Sport models
came with a 22mm front and 16mm rear bar. Needless to say, my
Neon has more body roll than the "Performance Trim" Neons, though it
has less weight (manual windows, manual door locks, no tilt steering,
no rear wing, no foglights). I've been wanting to fix this
for a while, but hadn't gotten around to it. Since I've been laid
off recently by the all-mighty Microsoft, I had time and some severence
pay to do so.
I had considered getting the Eibach swaybar kit, that comes with a 24mm
front bar, and as reported by some, a 21mm rear bar, but then I did
some research and found the rear bar to actually be 19mm. If you
check Eibach's Site on their Neon Kit, you'll find the following:
DODGE, Neon, 2 & 4-door - 1995-1999
(Incl. R/T & ACR Models)
| ANTI-ROLL-KIT |
24mm sn |
19mm sn |

2815.320 |
Oops. Looks like Eibach says it's a 19mm bar. I didn't want
a 19mm rear bar, I wanted something bigger, since I like a neutral to
mild oversteer setup in my cars. Understeer is something I wish
didn't exist!
I could have gone for the Mopar items, but even from the discount
mailorder dealers of the MP parts, it was quite expensive. The
front and rear bars as of September 2003 were at $98 each, plus $65 for
the rear bar installation kit needed for a car that didn't have a rear
bar originally, plus money for urethane bushings (Another $20+ just for
the front), it just wasn't price competitive, though the rear bar is
22mm. The old ones were adjustable, the new ones aren't, or I'd
have been tempted.
Looking around, I found the Suspension Techniques kit claimed to be a
24mm front bar and 21mm rear bar. This seemed a good balance to
me, and it came with all required bushings and hardware, other than the
brackets for the rear bar. Still, from Jegs.com, I managed to
pick it all up for $268 shipped, plus it was in stock, unlike Summit
Racing which was a 2-3 week backorder. Modern performance had
them, but wanted over $320 for the set with the required rear bar
adapter kit before shipping.
I ordered from Jegs, and the bars arrived a few days later, though UPS
goofed and delivered the package for the rear bar brackets a day late,
though they shipped as one shipping order.

Pictures of What You Should Have
Here's some pictures of the swaybar set hardware:

Here's the two bars, front and
rear. See how the rear bar has the endlink holes in the same
orientation as the front? On stock bars and the Eibach kit, the
end links are vertically oriented, rather than horizontal. You'll
see the reason for the difference in a moment. A bonus to me was
the bars are gray, not bright red like the Eibach kit.

This is what the ST rear bar uses rather
than the stock "barbell" setup the Mopar and Eibach units use.
The top is a horizontally oriented, solid urethane endlink bushing
arrangement, the bottom is a heim joint! The stock setup uses a
metal "barbell" shape with rubber bushings in the ends that bolt to the
bar and the bracket. This setup may aid in the stiffness of the
rear bar, or how it works. I don't know enough about swaybar
construction to say, but it seems less flexible than the stock setup
while providing with enough movement to prevent the bar from binding,
which would be bad since it turns the bar into one big torsion bar
spring, and makes the effective spring rate almost infinite. This
can cause some quirky handling and tends to unsettle the car on
mid-corner bumps.
Here's the hardware for the front bar:

Replacement bolts for the end links,
solid urethane endlink bushings, spacers, and a number of cup
washers. You can also see the solid urethane front swaybar
bushings and the packet of bushing lube. These are all included
in the box.
Here's a shot of the rear hardware:

Present are bolts for the end links, two heim joints, a number of
urethane endlink bushings, urethane rear swaybar bushings, and a number
of cup washers (stacked in this photo) and the bushing
lube. The nuts are all nylock locking units so they don't
come loose inadvertantly.
The biggest thing you'll notice is the steel brackets. These
replace the stock units if you have them, and provides them if you
don't have them. The stock units are thin steel, and tend to
flex. You can purchase aftermarket stiffened brackets, but
there's no need if you get the ST kit, since these are significantly
thicker and stiffer than stock. Not pictured are the "adapter
kit" brackets, which are little more than stock mopar brackets and a
couple bolts. These are the brackets that hold the swaybar
bushings to the subframe. Thus far I'm impressed by what's
included in the package, from what I've seen the Eibach kit includes
little more than stock hardware, and I'm confident I made the right
choice.
Installation
Realize that I have a Highline Neon, so it has no stock rear bar, so I
can't say much about the stock components of that rear bar. I'll
explain what I know, however.
First up, jack the car up and get it on jackstands. You can do
just the front, rear, or both, it doesn't matter what order you do
this. Take the wheels off, you might be able to leave the front
ones on, but it'll be easier if you remove them all. Take the
opportunity to rotate your tires if you've not done it in a while.
Front Bar
Unbolt the stock bar. You'll need a 13mm wrench and a 13mm socket
to do this. Unbolt the end links first, they come off in three
pieces, then unbolt the brackets that hold the bar and its bushing to
the k-frame. It should drop free. Keep only the brackets
and the bolts, you won't need the stock end links, these are replaced
by the ST bar kit.
Lube the inside of the round swaybar bushings. Use rubber gloves,
or else you'll never get the grease off your fingers. Supposedly
WD40 works, but I never needed to try it out since I wore gloves.
Don't be shy with it, use the entire packet, there's a seperate packet
for the rear bushings. Snap them over the new bar, be careful,
it'll be tough to do and if you get your finger caught, it'll hurt like
hell. Get under the car, you might want a friend to help
here. Lift the bar into position, and bolt it in using the stock
brackets. Get them good and tight, the bar will still rotate on
the lube.
Assemble the endlinks by taking the long bolt, and sliding a cup washer
down on to it, followed by a endlink bushing with the raised side up,
the flat side against the cup washer. Slide it through the end of
the swaybar, followed by another bushing with the raised side down, and
a cup washer. Slide on a cup washer above that, followed by
another bushing. Side the bolt through the hole in the control
arm, then a bushing, again, raised side down, then a cup washer, then
thread on the nylock nut. Do the same to the other side.
Torque them down using a 14mm wrench and socket until the bar end holes
come up into the bushings and become flush, and the bushings deform
slightly.
That's all there is to it. Here's a picture of the installed
bar.

The right photo is of course the installed bar. You can see the
Quickor suspension bobble strut in the picture too.
I'm not a big fan of red bushings, but at least they're all red.
The right picture is the top bushing of the swaybar endlink. Note
the nylock nut.
Rear Bar
Take the wheels off first of course. I again had no rear bar
stock, so I'll approach this assuming you don't
either. If you do have a rear bar, simplly unbolt everything,
keeping
only the brackets that hold the swaybar to the frame and the associated
bolt. The rest is junk, not needed by the ST rear bar.
Don't reuse the stock brackets that bolt to the strut, they won't work
with the design of the ST bar most likely, and the ST units look more
than sufficient stiffness wise. If you still want to use them,
take a closer look, perhaps they can be modified or reused, I can't say
since I don't have them in front of me. Use your own judgement.
Undo the nuts from the two big bolts that bolt the strut to the lower
suspension. DO NOT REMOVE THE BOLTS. This will possibly
goof up your alignment if you do. The bolt end is 15mm, the nut
is 18mm. Once the nuts are off, slide in the proper
bracket. They are side specific, so make sure you get the proper
one, it should be fairly obvious. The curve of the bracket should
go toward the middle of the car, so it clears the drum brake or disc
brake on the rear. Bolt it back on to factory torque, in other
words, damn tight. Do the same to the other side.
Lube the swaybar bushings, again using gloves. Snap them on to
the bar. Grab a buddy preferably, and thread it over the rear
suspension and over the exhaust. Use the brackets that came with
the adapter kit, or if you had the stock ones, re-use them, and bolt
the bar up to the frame. The holes to do this are on the outboard
frame rail near the rear wheel well. You might want to spray the
holes out with WD-40 or similar, especially if you live in a region
with a lot of salt, etc. Here's a picture of the installed
swaybar bushings:

Take the long bolt for one of the end links. Put a washer on,
then a cup washer, then an end link bushing, flat end toward the cup
washer once again. Thread through the hole in the rear bar, then
add another bushing, another cup washer, and the spacer. Thread
on the narrow non-nylock nut all the way up to the end of the
spacer. Leave it loose enough that you can move the bolt around
in the bushings. Don't torque it down so it can't move yet, you
need some flex in it for the next step.
Spin on one of the heim joints until it buts up against the nut.
Put in the shorter crossbolt with a washer on it through the bracket on
the strut, then the spacer on the other side of the bracket. Then
put the bolt through the opening in the heim joint, followed by a
washer and the nylock nut. It will be a difficult fit, but you
shouldn't see any threads of the bolt between the heim joint and the
nut. Then use a 14mm open end wrench to hold the thin nut, and a
ratchet with a 14mm socket to torque it all down. Make sure the
nut is tight against the heim joint as well. Only tighten until
the bushings start to deform slightly.
Here's how the end link should look installed:

As you can see, it's quite different
from the stock setup if you've ever seen it. The only real flex
is in the bushings, which are 90 degrees off from the stock bar.
The heim joint alows flex for the suspension to move during body roll
to prevent binding.
That's it, put the wheels back on and go for a careful test drive to
make sure everything is tight. Once you're sure, go take some
quick corners and enjoy the improved handling.
I wasn't able to fully test the limits yet due to the starting to rain
as soon as I dropped the car off the jackstands, but I did drive around
a bit. It felt a lot more stable in the corners, as well as
helping to cure the "squished against the door" sensation during
extended cornering on long sweepers. At one point I managed to
pass two cars on an uphill off-camber hairpin at a speed that before
the bars were installed would have caused some very awkward front-end
plow followed by the inside tire spinning. I went by them easily
on the uphill run after that. I guess I'm just an "agressive
driver", but they had messed up my corner carving for a good two miles
before that! :)
