After market front springs/ suspension 74 DART
Hey I'm replacing the majority of the front end on my 74 dart swinger mainly for increased feel and road handling. It has some real janky tugs coming around.
I know the K bar is a little bent. The A arm is a little bent. (both towards left side) and I'm planning to keep it without power steering, so the more stability I can get in the front is desired.
Now regarding the suspension, I just ordered some new bushings http://www.jegs.com/i/Energy-Suspens...8104R/10002/-1 and figured I would try to find some really nice springs/anything that you guys might recommend as well.
Thank you vary much ^_^

Bilstien shocks are a popular upgrade if you wallet is thick enough. When i rebuilt the suspension in my Charger, I went with KYB shocks. They have some haters though. I've been happy with mine though.

I'll continue browsing the interweb and as the front continues to get stripped, I'll make my orders! Thanks guys

In all honesty I'm still a little confused on whether I need shock absorbers or what? keep in mind my main two focus, along with increased handling of course, are the ability to hold a small block 318/383 a,d gain a height advantage without strut and ball joint damage. the rear is fine, for now I'm only working the front end
These threads are mad helpful!

I did turn the torsion bars about 3/4 of an inch, but kind of wanted to go another quarter. That's why I'd like to add the coil overs to take some stress off the torsions? I don't know if I'm right about that, but after putting a small block in I will especially need to give extra support
#12
The car height is determined by the torsion bars. I don't know of any company that makes a bolt in "coil-over" shock. Even if there were one, it is a terrible idea. The upper shock mount in your car was never designed to support the weight of the car. It is relatively thin sheet metal. It is perfectly adequate for the task it was designed to perform: To support the shock absorber. The shock absorbers job is to slow down the movement of the suspension.

I have used the .85 torsion bars in 318 and 360 cars. They are the standard V8 car bars from 67-76. They are a little soft, but they work. The .87 bars are the stock 340 bars. .89 are the 383/440 bars.
My brother in laws 72 Duster currently has .85s, but we will be installing .87s when the car is ready to be aligned for street duty. I just finished the paintwork and buffing. Next up is the interior.
The .87 bars, KYB shocks and fresh bushings make a good street package. I also made a custom front sway bar by modifying a 1.25 bar from a 2wd GM truck. We will be using a 3/4 rear bar. This should result in a very flat cornering condition with some mild understeer to keep the driver safe. The engine is a low mile rebuilt 360 with a 340 cam, a Wieand dual plane and a Holley 600. The car roasts the tires for 100 feet as is, so I expect that whatever understeer the car has could be overcome with some input from the loud pedal.
Moderate torsion bars & spring rates add up to a more comfortable car on the street. RACE cars on smoothe tracks can benefit from stiffer t-bars and smaller sway bars because they don't deal with potholes, expansion joints and other rough surfaces like we see on the street.

These are the shocks you speak of? are you placing them all round? http://www.jegs.com/i/KYB/575/KG4509/10002/-1
Yeah i purchased these bushings about a week an a half ago and they should be here by Wednesday (thanks back order) My plan being to dismantle the front to replace bushings, and replace whatever is wrong that I can find in the process from arms, joints, you name it. http://www.jegs.com/i/Energy+Suspens...8104R/10002/-1
I want this old girl to handle like a dream without power steering and have clearance for the big boy 215/70/14 tires on the front.
THANK YOU EVERYONE FOR ALL THE INPUT ON MY POSTS!!!:swinging ::::hail: :drinking::drinking::dri nking::drinking::drinking::drinking::drinking::dri nking:

I had .920 T bars in a car I called the FrankenDuster. It was a 74 that I backdated to look like a 71 Duster 340. That car rode fine with those bars. It also had a 1 1/8" front sway bar and KYB shocks. The link you had showed a strut, not a shock. Maybe they just had a generic picture there instead of the actual one for the application?
I am into cornering much more than drag racing. Some cornering guys claim that these cars ride fine even with 1.14 T bars, but I'd argue against that. I have 1.03s in a 67 Dart. It rides okay, but a jump from there to 1.14s is huge! .92s are a decent choice. A taller sidewall will cushion the ride if the t bars are too harsh. I have 1.0 bars in the 70 Charger. It rides nice and corners like a madman!

Do you guys have any suggestions for sway bars or control arms? I know once I begin tearing down the front end for the bushing job I will find more things that need some loving and I'm just planning for the worst tbh.

Idk they said shocks in the part listing but I did notice that. So how did the .92 t bars feel? I almost want them to be tough to keep the front end up in the air enough for these tires. (mind you I say it again, I couldn't get any tires that matched and weren't backordered for a damn year. I ended up getting cooper cobras. 215/70/14 front 135/70/15 rear. You think that would cushion well??
What else is on the charger making it handle so well? have you put power steering?

Oh crap... NOT that dang AlterKtion stuff again!
Regarding the Charger, I decided to maximize the factory design instead of spending $4500 on a design that is inferior to the factory stuff.
I fabbed up subframe connectors out of 3x3x .120 wall tubing. They are welded in along with front and rear torque boxes. The K member has been fully welded and the steering box mount has been reinforced with added gussets and additional welding. I added a steel plate to the bottoms of the lower control arms to resist deflection. Front end has 1.0 torsion bars and KYB shocks. I modified a GM truck front sway bar to fit the car. The 1.25 size is the largest that can fit through the K member. There are a few vendors that offer a 1.25 bar, but mine cost me less than $75 to buy, modify and install. Front end alignment is 1/2 degree NEG camber, 4 degrees POS caster and 1/8" toe in. Steering box is a rebuilt Firm Feel stage 3 with Fast Ratio pitman and idler arms. This makes the steering ratio a tad under 12 to one, compared to 15.7 to one for regular stock idler and pitman arms. Rear has HD springs with 6 leafs and a 7/8" sway bar, KYB shocks.
I love the way my car handles. I enjoy cornering FAR more than drag racing.

Do you know anything about making repairs to a K member
#24
Repairs? Yes.
I have converted 5 or 6 slant six k members to the 73-76 V8 style. I have repaired K members with damaged LCA mounts too. Upon the advice of some sharp guys in the hobby, I have welded the seams in several K members to increase their rigidity. I have also added gussets to reinforce the steering box mounts so that when the steering wheel turns, the steering box responds without whipping around side to side. The guys racing the Challengers and Cudas in SCCA used modified K members and reinforced steering box mounts as well.

Re-visit this. Do you guys have preference between lakewood and kyb gas-a-just shocks? the application would be cruising, light races, and perhaps a trip or two a year to the track. ratios recommended for the front end? Also it needs to supprt a small/big block
You don't want drag shocks. Check out the Green Brick for some ideas.

Never even heard of this company before, but they have so many different shock applications.. but none that outright fit the dart. I'm not up to par in order to make altercations to the car to fit these

They look correct. for the front IS the K member bent or the frame ? K member is not difficult to replace Just takes time Even easier if the motor is out..
