...best rear springs for Street/Strip?

[66cornet]

I am looking for any input on Cal-Tracs Split mono leaf vs. Super stock Springs
Price is comparable but there is some weight savings with the split mono's. They are new techonology too!

...Any one have any thoughts on which is better/worse and pros vs. cons?

From what i hear..... Cal-Tracs all the way.....

[LA360Dart]

Hello 66cornet:

I have run both set ups on the same car, a 73 Dart Sport340 the car weighs 3650 with me and best 60' is 1.78 with superstock springs. The CalTrac best 60' is 1.81' but car is way more consistant with CalTrac. Car runs 12.80-13.20 at 103-106 mph depending on available air. The SuperStock spring set up varied between 1.78-1.95 on the 60' time. The CalTrac set up varies only 1.81-1.86 on the 60' times. Hope this helps

Denny

Once you get them dialed in the Caltracs are infinitely better-no comparison. I've seen cars run in the mid 8's with Caltracs. -Bob

If you go to an NHRA event look at Stock-Eliminator cars. Many run Cal Tracs links AND Cal Tracs slit mono leaf spring, THEY WORK!!! I use the Cal Tracs bars with stock spring on my 67 Plymouth on the street. They seem to workbetter then the old style adjustable pinion snubber. Soon I'l take it to Fontana to see how my 60 ft. times improve.

Cal at Caltracs told me he does not recommend them for a street car.
Also, if a monoleaf breaks, you are DEAD!! Your car, at speed, will probably disintegrate all over the road. Last I heard, Caltrac had one break. ESPO are supposed to be good springs. SS leafs make your car tilt in one direction. Also, they are not consistent as far as how high it will raise your rearend. ESPOs can give you specific rear end lift height numbers.

If you look at Stockers, they also run pother set ups than Cal tracs, and they work too. So, it's not so that one system will "save" you when everything else doesn't work for it. I have run 1.39-1.40's with regular SS springs, ET Streets and rancho shocks. Also tried cal tracs at one point, but nothing changed, so I sold them and went bacl to SS springs. There are other possibilities too, but for the money spent the SS springs are hard to beat. As far as the height goes, you can use lowering blocks to even pout the height. May sound strange, but it works too even with different thicknesses on both sides.

Where can I get more info/pictures on lowering blocks for my 72 Cuda?
Are SS springs made in Mexico like other cheapy Mopar HD Springs were?

[BELVEDERE2]

I know the SS springs I have are supposedly junk steel. I had them for less than a year before they lost height. But this was at least 6 years ago. Maybe they've changed their supplier by now.

Sad to say, but Mother Mopar does not have trouble selling junk once in a while. Look at their first round of crate engines.

[cudabob496]

But, if you use lowering blocks to level out your car, then you lose your tire clearance in the back. Thats why I like ESPO. Quality steel, and you can specify one inch or two inch tire clearance, so I hear. I'll be getting some soon, as I had to go to shackles to compensate for the junk Mopar sold me!!!

[DartGT66]

There are also other spring manufacturers, for example tri city competition launcher springs are also widely used in Stockers. They have the same basic idea as the SS springs, taken to the next level. I have even built my own "race springs" out of old used factory springs, using only the upper leafs and cutting them to desired lengths and using desired amount of clamps. Basically I had all the fornt section springs go almost right under the front eye and clamped "solid", and the suspension was handled with the rear segment. I left the rear segment leafs pretty long too, adn then "adjusted the suspension by cutiing them shorter. They worked surprisingly well too, and the cost was maybe some 20$.

Before long your riding around on the pinion snubber!

[DartGT66]

Even according to mopar performance, with SS springs and automatic transmission the pinion snubber is there just for "safety". I didn't use it at all, put it close enough to the floor and you have about 1/2" of suspension travel in the rear, pivoted from the center of the axle. Not quite the safest option..

Don't forget to look at the CAL TRACS split mono leaf rear springs. Look at stock eliminator Mopars. They wouldn't use them if the CAL TRACS springs and traction bars didn't work.

[Duder]

I have SS springs on my T/A. 4 years old and no loss of ride height.

[AdamR]

SS springs are great and well hey just look at the hemi ss cars and times they are running, they're are also a mucho experienced race crew.

If it was me I'd go with the caltracs for racing, I want to try them anyways after hearing the raving about how well they work.
