I tried 002, and 003 SS springs with Caltracs in 1999. Didn't work. The bump valving needs to be pretty stiff, or it will wheelhop like you won't believe. I remember thinking "my overrunning clutch is dieing", as the yoke pounded the floor pan. That was with QA1's set below 50%. That was running 1.45 60's, with 5800 flash.

I'm using Caltrac bars, mono leafs and QA-1 single adjustable shocks. Stock rear shackles with NEW rubber bushings.
No issues, set the preload (and pretty much forget it) and use the shock adjustment on a given day for track conditions.

The sliders are nice.. just keep them clean.. what

are hard and tend to bind up.. if you run shackles
the old bushings can cause issues.. they can bind
then snap free.. chassis's dont like to be upset..
thats part of the reasons that people really like
the sliders.. they put a new item on the car that
isnt binding... plus the sliders lower the back of
the car and in most cases that helps on traction
(gets the CG down a little more so its easier to get
the front over the CG point)... but if people would
just lube the rubber points now and then it would help





P-Body dude... I have Caltracs and Caltrack mono-leafs. I have brand new rubber bushings in my shackles. What would changing to sliders do for me? How much maintenance will I have to do on them to keep them working?

If you keep the rubber bushings lube they are fine..
the sliders usually lower the back of the car about
1 1/2"... that can help the launch... keeping them
clean is just that.. spray them down with lube once
in a while... by the way I dont care to be called dude..
its just a thing

Depends where you put them. I mounted mine on a plate right next to the frame rail. Exact same ride height. If you had an inboard spring kit, they would actually raise the car slightly.

My ride height didn`t change much ether since I lowered the rear shackles years ago when I moved the springs in and tubbed it.

Dizuster,

I am looking at the direction of your Calvert spring slider, and I have mine where the "Arrow" that is cut into the top of the slider mount is pointing forward...did I install mine backward?

Thanks for the help.

The arrow on the Calvert sliders points forward, with the car at rest, spring bolt should be a little more than half way to the rear of the slot.

Johnnycuda, Thank you, and I have mine mounted correctly...big relief!

I will try my SS Springs first, and if they don't work out, then I will get the Mono-leafs...I was worried that the Monos would be too stiff for the street, but then again, I don't really drive the car on the street that much.

1 or 2 of the front leafs may be wider than the stack so you just file/grind to fit the cal trac travel.

I have the speedway motors sliders. No forward/rearward on them.

They are cheap too...

I tried the Cal-Trac and SS spring combo and there was a violent confrontation between the two that I'm sure is not healthy on an automatic transmission.There could possibly be a shock package that might tame it down but then you would be close to the same money for the mono's

Well, I am now sold on the Mono-leafs, and will order them next week, and will not even try to get the SS springs to work.

Thank you for all of the advice!

Like anything else, once you understand how it works you`ll be way happier.

I also tried that combo on my dart . ss springs and caltrac bars. I tried every adjustment possible over 4 or 5 trips to the track.

It doesnt work !

even got John Calvert on the phone for a few tips. He also told me the Mono leaf has a much higher spring rate than the ss spring.

We added Cal Tracs to worn out SS springs once on a low 11 sec car. Car was instantly dead on in 60'/ET, EVERY pass. The SS springs were way worn and the car was all over the place on 60' and thus ET.

Later we, added the mono's just to lower the ride height and nothing changed. 60'/ET still the same, albeit as I said before deadly consistent.

Maybe our deal was different at our (lack of) power at that time???
