Hi everybody. This is my first post but im having trouble finding answers to my questions. Hopefully someone here can help me understand this science better!
Be prepared, its long!!
Ive searched the archives on other forums and still have questions about what the ideal spring angle would be for a street/strip truck (in my case). By spring angle, i mean the line drawn thru the front and rear eye on the leaf spring.
Ive heard that the farther out infront of the car this line intersects the road, the harder the hit and better the launch... But im sure there has to be a point of diminishing results.
I'm wanting to lower the back of my Dakota about 2" to level out how it sits, and I want to go about it by raising the front eye. Since I will most likely be making some custom spring hangers to do this, I have the chance to make it in the position that will work best.
Is there a "rule" for this? or is each car on a trial and error basis until its perfect?
I also know that the shackle angle should be kept in mind. Ive read the MP Chassis book, and it left me unfulfilled. It did mention that raising the front eye, and bringing the car back to the same ride heigth will increase rise, but what happens if i raise the eye but keep the lower ride heigth?
Reading through some other threads in the past from Moparchat.. and maybe i was reading this wrong .. but it sounds like you'd want the front eye to go LOWER for best hookup, especially in a truck where the weight on the rear is less. Is this right or wrong? Here's the thread:

Im somewhat confused tonight as to whether I should raise or lower my front spring eye to aid with traction. I seem to remember somewhere it being mentioned that you want the front eye raised. People had talked about flipping the front spring mount on a car so the offset mounts will raise it.
Can someone please explain how raising and lowering the front eye affects how hard it hits, the launch, and raising of the front of the vehicle?
I have a set of Caltrac bars here and plan to use them, but I also want more of an understanding to what physics cause them to work. Ive heard "Cal Trac's will lower the eye".. but how so? Does the attaching point at the front of the transfer link (the bar under the leaf) 'become' the spring eye? And when you move th bar from the upper to lower attaching point, why dose it change the car? Is it the angle of the bar? Or the length (leverage) it gains on the front pivot bracket?
It would be great if i could get any helpful input from you guys, as i am ready to construct my spring hangers and I would like to have everything in consideration.
Thanks!!!
