NEED to use a housing floater set/up for best , springs and ladder bar have different swing arch, they will fight against each other
all parts are sold as is, all parts are considered used no warranties or returns
paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred

Mostly ladder bar floaters, but I know of two Hemi S/S cars using a floating four link with monoleafs that work fine. My Duster was built at Jeg's in '78 with ladder-leaf. The leaf springs hold the rear up, but have a skid that glides across the top of the spring when the car is moving. Kind of crude, but it works well.

If you are starting from ground zero with nothing done yet, go with Caltracs. We have been looking into rear suspension for a while now and took out the ladder bar that was very crude set up built by a previous racer but still ran in the 8s with it. Fixed the floors on the Cuda and putting in the complete Caltrac Systems with Mono Leafs and back slider. You get to set you own ride height and various over things to make this work and fit better that we needed because the front segment of the spring need to be a longer that the 20 inches of a front super stock spring. Talked to Caltrac and they were great help.

Floater kit. I like the Moroso/Competition Engineering style.
That's old school. I'm not sure the Calverts aren't a better choice. Ron Rhodes does OK.
If the results don't match the theory, change the theory.

The springs do nothing but hold the car up with ladder bars. Any spring can have the rate adjusted to change how the suspension reacts.

In my eyes a waste of time. If your installing ladder bars you need good shocks anyway. That means you're buying a cheap pair of coil over springs instead of floaters. It's a no brainer. Now if it's already set up with floaters maybe?. But chances are the leafs are to stiff anyway. The coil springs are cheaper than monos.
Doug yes a complete waste of time

Won't let the suspension work though. Same as a too stiff spring. Actually the shocks control the speed of and/or restricts the housing movement. A lower rate spring, compressed more to hold the car at the desired ride height, and storing more energy as a result, will make the suspension respond differently than a stiff spring. Coil spring, leaf spring, torsion bar, doesn't matter. A lighter spring will make the car more "lively" on the suspension. A big. fat torsion bar will hold the front of the car up with little compression needed. A skinny torsion bar, twisted up to hold the car at ride height will store energy and help get the front suspension separated and get the car to pitch rotate at the hit. Same principle.

Those long strap hangers look cool on a red neck car when used to jack the car back to normal ride height. Or maybe re-arch the spring looking like a big U.

Lighter spring will have a larger arch, but be compressed more to get down to the desired ride height, which typically is as low as possible. Low rate front coil springs (Moroso, Landrum, etc) are typically longer than stock springs, are a b###h to get in, and the car will sit at stock height or lower.
If the results don't match the theory, change the theory.
