Dragin... Did you have shackles or sliders at this time ?
Cracked..Though I agree clamping the front of the leaf helps.
Unclamping the back of the leaf
plays a more important role
in allowing articulation of the axle housing under a load.
as well as having shackles vs. slider brackets to allow axle seperation/Rise from the chassis.
If I Were to USE sliders I would design them
similar to brackets found on Semi tractors
where the leaf spring is Allowed to SEPERATE from the frame
(within the bracket...Not Slotted like Dragins)
when the pinion climbs the ring gear
Under the Torque of acceleration .
The purpose of clamping the spring is to keep the main leaf of that front segment from going S shape from the combination of twist and forward thrust, and then springing back and thus hopping the wheel as soon as the snubber contacts the floor. It really has nothing to do with traction per se.
Unclamping the rear in essence makes the back half of the springs more or less disappear during that initial axle rotation so that the snubber can contact the floor with full impact driving the axle into the ground. That's the purpose of having the long shocks. Contrary to popular opinion, if the relationship between the springs, snubber and chassis of the car is correct, the only reason to have shocks back there is because the rules say you have to have them.
