I have a 74 Duster with a mild 360 and would like your opinions of the use of a complete set up of Cal-trac components for front and rear. Would this be a good set up for mainly street use and an a trip to the track occasionally?

If you don't like Cal-tracs, which way would you go and why.

Thanks Gary

Why would you want to use Cal tracs? Mopar springs and stock axle placement will never wheelhop unlike Ford leaf springs.
I've run a 360 A body as quick as a 1.55 60' on SS springs.

Lighter weight perhaps. A single mono-leaf will not weigh as much as a pack of leaves, although you may give that up with the traction bar.

Which begs the question, what is the actual weight difference?

I also am curious how these feel and perform on a predominately street car application.

Don't think I'd spend the $$ if this was just a street and occasional strip car - SS springs will work just fine. But if you are building a serious torque monster or need every bit of E.T. from your leaf spring car then the Cal Tracs are the way to go.

Or if you don't want the rear of the car to sit a foot higher than the front.

I now have SS springs on the rear and the rear end was in the clouds, added 3" lowering blocks and I'm back to normal ride height. I also have a second hand set of competition engineering 3 way adjustable shocks on all 4 corners. I just wanted to know if I could improve on this set up by replacing with the Cal-trac system. I checked with Calvert racing and the entire set up would be $953.00 plus shipping. The Cal-tracs would have to be real superior to shell out that kind of dough is this crappy economy. I have my shocks set in the middle range. Is this correct? Thanks for the help.

I wouldn't spend that kind of money on a car that runs 13's. There are much less expensive alternatives and ways to get the SS springs so the car isn't sky high. Flip the spring hangers over. I remember one suggestion of B body SS or the 2800# springs on the A's.

I know Sloan swapped out from SS spring to Cal tracks and the car made a big difference in 60' and the way the car left the line. Nice and level, no more left wheel high, car sit level now. It does run mid 10's so the comparison to your car isn't the same.

I don't run SS springs on anything I own.

In my humble opinion.. I would never use SS springs unless the car was strip only..

A couple of years ago, I researched Cal Tracs vs SS springs, I spoke with several of the racers over on the Unlawful race board, I read as many of the old threads that I could find and the majority of the seasoned racers recommends the Cal Tracs. They are easy to install, they offer a smoother ride, they are adjustable for different levels of bite. They are affordable and best of all, they look pretty cool sitting under the car..

With the SS springs, the only advantage to them are the stiff, firmer rider and as said above, will raise the back end of the car.. So if you're looking for that old school 70's look, then SS springs is what you want.. if you're looking for softer ride with a lower more modern stance and something you can adjust for going straight or racing on a course.. Then Cal Tracs is the answer..

Yeah, I'm glad I went with the Cal Tracs

I bought the Mancini SS springs for my 63 and it sits just right. Don't know who makes them but my ride height came out just right. I agree Caltracs are the best for the most et but my 63 is a street car with a few trips to the track each year and it's not worth the money to me to buy the Caltracs as I am not worried about getting every last tenth out of my car.

The ride is somewhat stiff and the traction with the MT ET street radials is excellent.

If it is mainly a street driven car I would not do a Cal-Trac setup just because street driving will beat up the parts, as will moisture and dirt.

For the money I would use just a set of ESPO heavy duty springs and a pair of Lakewood slapper bars. My Valiant went 1.56 in the 60' and a 12:00@110 on Lakewood clamp-ons and ET Streets.

You could not give me a set of SS springs, but that's just me.

Dennis, you are by far more experienced than I am.. but with all due respect.. what parts are you talking about?

And prepare for the "Slapper bars on a Mopar??? " wherever you go.

Rod ends and the aluminum spring eye bushings. The steel sleeves will oblong the holes from dirt. The rod ends will also rust into the bars if you do not keep them well lubed.

I had Lakewood bars on a 70 'Cuda back in the 90s'

I heard it MANY times. Long before Moparts

The new superstock springs that you buy now are made in Mexico and are junk compared to the old ones. We have cal tracs on the Duster 12.40's and on my Coronet 10.20's and they are both street driven. No lowering blocks,no slapper bars for us

Not to mention the lean or sagging set that SS springs take, don't they need to be replaced after a few years anyways?And now they are heche in mexico...nice!

I had switched out the SS to cal-tacs on my 65 B-Body, I got the car to sit low (I prefer that look )without using lowering block (which tend not to help traction) it moved pretty good with the 4 speed on the street.

If you search around you can find the parts needed much cheaper than the price you stated, someone had the bars and springs for sale around 500 bucks on Moparts.

And yes, any performance car will need a little more maintenance but isn't that part of the fun of owning something old and fast?

Now lets talk about slapper bars and Mopars, what are you making a Blade Charger replica?
