Here's how I see it..........
To understand the basic fundementals of how the Caltrac's work........
they are a "Poorman's 4-link". And that's not a put-down. They turn the leafspring into the "upperbar" and work like a 4-link with some built-in slack (or not).
Where I'm situated...............
CalTrac's w/stock 4 or 5 leaf springs and drag shocks would be most cost effective.
Then, sell CalTrac's, to upgrade to a Ladderbar set-up if I'm going to mini-tub. Lose the weight of the leafsprings, gain tire clearance w/o the cutting to install the boxes to more the leafsprings.
