rear springs with caltracs
 

Hey everyone. For those of you running Caltracs, are you running the split monos or a multipack? If so, what spring rate for the multipack? I have a 71GMC short box with big block and a 4 speed and hoping I can get it to hook. Its a street truck but might see the track a bit. It has a 12 bolt with 3.42s. Thanks, Troy.

I'm dong a bunch of work to my suspension right now and Caltracs are part of the project. I am going to be using the stock springs that are 3 leafs and the over load. I'm hoping with good shocks and 325/50R15 M/T's it will hook my 496 TH400 3:73's.

This is what I have except I have removed the overload.

I have been using stock type springs for about 8 years...I'm needed to replace my 3rd pair. The first (originals) broke...I blamed it on being old & scared to death, the replacements bent & so has the set that is on there now. I have purchased the parts to make an anti-roll bar which seems to be the problem. The main Right spring seems to flatten out & the Left one kinks toward the front. At some point I may go to the split mono's.

My advice, If you are going to use multi leafs & are going to the track with sticky tires...do the anti-roll bar now. Lorne

It goes 1.56-8 60' times. You can see some rollin' over going on.

We ran split monos on my friends 67 Camaro and had 1.42 60ft on a 200 shot progressive with a 275 60 15 drag radial

The split monos fix the bending problem . The front half is very thick and the rear section is actually the spring rate portion .
