I am thinking about putting cal-tracs on my belvedere,should I stay with 20" front seg.or go longer?Springs are already moved into the frame so fabbing for longer springs is not an issue.Thanks,Sam.

Longer. Use the chevy length spring.

I can't remember the exact front segment length but I'm pretty sure the spring for an S-10 pickup has the longest segment. There isn't one "Chevy" length. It depends on the model.

Pretty sure the length everyone uses is 25". Stock Mopars are either 20" or 22" IIRC. If you talk to Calvert Racing about the monoleaf springs, they'll tell you.

I went with the chevy front segment length, its 25 inches. Calvert will help you on the phone with spring selection.

So if you run a longer front segment do you have to compensate by moving the front spring hanger forward?

Yes, by how ever longer you go with the segment. To keep the axel in same location.

$$$ good shocks is my guess. On really really fast car anyway. Like custom Mencer or Santhuff.

I still think the longer segment is the way to go but after talking with Menscer's tech they've convinced me they can make the 20" work. I even gave them the option of the longer spring and they said it's not needed. Since I already own the shocks its just the cost of the valving. I'm looking at the same money to relocate and (re)buy the parts for the springs.

I still plan on mounting the shocks straight up, and maybe move them to the front of the axle.

For the OP - I'd still go with the longer springs. I haven't heard anyone report regretting doing so.

Got it. Are you using the CalTrac bars, Assassin bars or something else?

Was it the extension part you had to work on firming up?

They changed both settings.
When the car was in the 10's the afco DAs worked good .
Now that it's in the 8s it just over powered the afcos the way they were valved.

Guys, I'm really confused with this possibility to change front spring segment lenght.

My concern is about front hangers, I'm using relocation spring kit and can't see how I can move hangers forward as you can see in this example attached.

Pictures will be great!

Thanks
