My rear leaf spring shackles are binding on the frame and are not at the right angle at ride height. It has the off set shackels but still hit. So im going to install the sliders to correct my problem. Has ladder bar and leafs previous owner installed. Did a decent job execept for the back part.

Thats exactly the same one I got from speedway motors. I have alot more overhang on the inside than you do. Was thinking about adding some angled bracing on the one side. Have you run your car with them if so how do you like them?

Not yet. Soon I hope. With the suspension unloaded , I set the spring eye all the way forward , so with weight , I think I'll be in the ball park. I tested and decided on locating them here by placing the car on the ground and putting ballast ( me ) in the trunk.  Should be close to right.

As it was a while ago when I installed a set of sliders, the information I found on their installation stipulated they had to be installed in such a way that the sliders movement was along the centerline of the two spring eyes. Has anyone else seen this info? *EDIT* I found it here http://www.afcoracing.com/tech_pages/leaf.shtml

Todd, I guess this answers a question I asked last year, Sliders can be uses with SS springs. I have moved my springs in the 7/8 or 3/4 of an inch. I had a set of sliders and returned them. Now the big question are you still running the ladders with the leafs (Ladder/Leaf) or just the SS springs? Do you have the front segments of the springs clamped up as well. Intrested to see your results. I have a 74 and want to add sliders to the SS springs but there is very little data out there to support this. there is with Mono Leafs thats for sure. let me know please what you have.  Kiddart
Thank you

It has ladder bar and leaf springs. The main reason I put the sliders on was because the previous owner had installed the ladder/leaf setup and had off set shackles in the rear but were bottoming out on the frame. So instead of notching out the frame to gain clearance I installed the sliders which seems to work alot better. Havn't got the the track yet as I still have some odds and ends to finish.
The rear springs arn't SS springs but are a lighter rate because all thier there to do is hold up the body. The ladders do the rest.

Then I am back in the dark again would it be worth putting the slidders on a SS set up?? I dont know? when I ask I never get a yes or a no iget theory!!?? It would have to free up the suspension I would think and with the front segments clamped should make it like a mono leaf
Thank you

Im no suspension expert, as may be evidenced by my comment here, but it seems that sliders on SS (or any) leaf springs alone would be a disaster. The axle would then be allowed move fore and aft with the springs as the rear of the spring slides. With ladder bars, they keep the axle housing positively located, and thus the slider movement is limited to the rear arch of the spring flexing. Essentially, without ladder bars, If you flexed the two springs independent of each other (which generally happens upon a hard launch), you would change the tracking direction of the rear end (???). Seems like you would be opened up to the car wandering all over the track, or making a hard left turn when you planted the rear end and flexed the suspension. Not sure I'm articulating this the way my brain is seeing it. I'll be interested to hear more on this from some experts.

The front of the spring holds the rear fore and aft
not the rear... the rear half of the spring is really
your spring/ride rate.... you want the front of
the spring as stiff as you can get it... thats why
the clamps on the front

One thing some can keep in mind if not trying to change ride height of the car, I measured where the oem spring eye was and built spacer boxes and welded the sliders to them and then the boxes to the frame. Never an issues, all works great, was concerned about the spacer boxes but welded good and the spacers bolted and welded no worries. I needed about 3 inches or so,(its been 4 years) in a spacer, I used 1 inch box stock, 4 put together and then capped off, possibly overkill but....on another f-body I have the spprings moved in and made the same boxes but they have a step to clear the frame and also provide alot of area to weld on as well. Nice looking setup ya got there This pic was with mopar springs, now have monos and same good fitment.

Again Raff answered most of the question. I get the part of the fronts as stiff as possible and thats what I have done. Now what about the sliders are they going to help yes or no. I get the point that a good shock is needed as well I have purchased the Ranchos from Calvert just really need the dark area of the question answered, will the sliders help or will theyt hurt on a Super Stock spring car. I guess I can ask when you put the sliders on your car before monos did it help the 60ft times at all
Thank you

Sliders maintain a consistent spring rate when installed correctly, a rear shackle because of it's movement will provide a variance. As the rear shackle moves, more force is required to get it over it's apex of movement, if you can visualize what I am talking about. They are used quite commonly in the Oval track world.

Correct... the angle of the shackle is always changing
the rate.... so yes the slider is better if a
constant rate is wanted(as in a drag car)

Yes I have seen that and part of the reason mine are setup as they are. Calvert has been doing this for years, yet mopars seem to be years behind some trends, they can give a wealth of info in a short phone call. To sum it up, they make everything seem to work smoother, if you can ever vid your rear chassis at work/launch it shows, smoother and it happens faster. Most I know have better results with a double adjust shock, because it seems not only do things move smoother, it happens faster with the sliders, on launch for a lack of a better term, when the rear axle transitions with the monos, it would extend the shocks very quickly and then id have traction problems. I slowed down the rate at which they extend so it wasnt such a shock to full extension and that fixed the problem. From zero arch mopar road race springs to calverts monos they are a good addition, calvert also sells them and give free tech as well. The distance between the bottom of the axle tube and the top of the leaf should not exceed 4 1/2..... says afco. Hmmmm..... Quote:
