I plan on using Caltracs with their mono leaf setup for my 65 Satellite build and was wondering if there is any advantage to using sliders vs stock spring hangers. Has anyone used sliders? What issue is solved with them?

I've only ever seen sliders used in cars with leafs and ladder bars or 4 link to eliminate suspension bind. With a single pivot point (the front spring eye) there's no need.
ETA...NVM. I was thinking about old fashioned slider/floater assemblies.

If the results don't match the theory, change the theory.

Yes and my Dart came alive and so far got a best of a 1.33 60 ft leaving on the foot-brake at 2500 w/more to come...........Also, move your shocks as straight up as possible if you can.........

IMo if you go for it,get the cal trac sliders.I got the afco sliders and then had to buy the correct bushing from Caltrac.Save the hassle and get it right the 1st time.The afco bushing are for mopar SS springs.

Much freer movement. Noisier. Looking at this and thinking...... with a mono spring & Caltrac bar setup, we all then use the shocks cranked down to as stiff as possible to slow the movement of the spring. So why would we want want to add a component frees up the movement of the spring? Not saying they aren’t a good option, just thinking out loud and trying to understand what we accomplish with each step. Thoughts......

Not saying they aren’t a good option, just thinking out loud and trying to understand what we accomplish with each step. Thouhts...... My way of thinking too, The sliders theoretically make the spring rate more linear than shackles. My thinking is if the spring rate increased the more rise you have, then that would be better? As a caveat I have no way to verify this but I can see the leaf running into bind quicker with a shackle rather than a slider but it's also dependent upon shackle angle.

What issue is solved with them? Both work well, sliders will allow the use of shock/bar adjustments a lot better.

I asked Calvert about the sliders and this was the response:
"We recommend the sliders for drag race or street/strip applications, not for daily driver use, as they will make a metal to metal sound when encountering road hazards, driveway entries etc., since there is no rubber or poly bushing in the rear spring eye."
"The sliders eliminate any potential bind in the rear suspension, instead of the suspension relying on pivoting on a shackle bushing and bolt, the spring rolls in the slider with two roller bearings per spring.
If a shackle is too tight or bound up in any way, it can cause the spring to not pivot at all or slowly, which can cause the suspension to hop or bounce on the tires, slow down the 60 ft and also effect the consistency."

Rear shacks still allow alot of movement but in a slightly different way. I mounted mine in a way that the spring eye is in the same location as the oem shack had placed it.
Although now as fast as some/many my street racer hits 6.0s at the track 1/8 and most the time I can dead hook on the street if its concrete, is it the sliders, no, just mix of good parts and the longest front segment of the caltrack bar I could come up with using, I think its 24 inches, "I think".
I dont like to copy others but if you look at some of the really really fast caltrack cars and they use sliders as well. I would like to know how you dead hook on concrete! Is the surface prepped at all? What brand and size tire ? What does your car weigh? I have ZERO luck with traction with no prep.

Mine are quiet as well.I'll just add no matter which method is used,a good shock is needed needed to control the movement.

Is the surface prepped at all? What brand and size tire ? What does your car weigh? I have ZERO luck with traction with no prep. I've been doing a few street tire events (300 treadwear or better tire) and had a couple of street races. I use 275 ET Street Pro's when I can, 110 lbs in the trunk directly over the rear bumper and leave in 2nd gear. I won runner up about a month ago at in an '80 and older true street tire class. 1.72 60 ft. And ran 11.70's on a true street radial. Here is launching on true street 275's. 20 psi.

M@H 325/50 DR, I can dead hook if some rubber gets down so I try to run mid pack, but thats foot brake vs off idle. Old Old concrete state highway. With the mt sportsman bias 28/12.5 I get a little spin but in a good way imo. Simple a body with coil over front, double adjust rear shocks and a S60 made between a early 70-s b body and c body width, iirc I the rims are 10 inch with a 5.5 bs. 3050 is the weight. Ive tried a std. hoosier 275/60/15 DR and havent had really good results Rear shacks still allow alot of movement but in a slightly different way. I mounted mine in a way that the spring eye is in the same location as the oem shack had placed it.
