Clat trac vs. SS springs vs 4 link

Maybe that is because MP sells pinion snubbers. Snubbers and Caltracs both perform the same function, only in different ways - mitigating or eliminating spring wrap. That is the whole point, two different approaches to solve the same problem, in the same type suspension. A leaf spring is a leaf spring is a leaf spring, and of course there are big differences but the basic principles in how they work is the same. SS are built way stiff up front to reduce or eliminate wrapup. I said this in another thread awhile back and I'll say it again: ANY spring will wrap, given enough torque and traction combined if something else doesn't break first. Where is the weakest link in any suspension and drivetrain setup? With enough power and traction, you WILL find it - the hard way. Caltracs and snubbers may be the things that eventually expose that weakness. Or get you down the track that much quicker. But none of those basic parts in terms of different types of leaf springs and add-ons is fundamentally incompatible. And I should add what hopefully everyone also already knows: Caltracs are much more efficient at this by transmitting that torsional energy "down" into the spring, as opposed to "up" into body the way snubbers do.
