heres a very very crude drawing i made for 3 different angles..the first drawing the front heim end would be lower than the rear heim, as the rear end torques it would be pushing the frame in to the ground is the way i think it should be...second drawing is the bars being level and the 3rd drawing is the front heim end would be higher than the rear heim end...

to me it seems like the first drawing would make the rear end sqwat down which should make it bite better

 

not exactly sure but wouldn't the first one try to lift the rear, will the middle and bottom would try to lift the front putting weight on the rear? I know on bag setups with for links the recommend the bottom bar be level at ride height for best performance.

 

the way the rear end torques it would be pushing the bar at a downward angle therefor pulling the rear of the frame into the ground...the way i built my caltracs i have mine like the bottom drawing but with alot of angle and it raises the rear end of the truck up..when i build these i will have holes to were i can adjust it up and down and have it level like the drawing does..i was just wanting to some other opinions

the arrows point to were the force is going

 

all that type of a setup is designed to do is stop the rotation of the axle, it will see a forward force perpendicular to the ground, try and keep the bar as level as possible to minimize flex.

 

here's a good thread on theory:

Good idea for mutli placement, but I wouldn't use anything less than a 3/4" rod/bushing. Alowing a decent 1/2" or material between holes for stregnth you would have a 4.25" plate off your frame and axle. With a lowered truck 6" ride height is pretty reasonable, but you'd only have 1.75" ground clearence at almot the breaking point of the truck. Long bars are a compromise. Your gonna have to do something more serious if you want that much adjustability.

 

Use the bottom setup because it will lift the front of the truck, therefore planting more weight on the rear axle giving you better traction.

 

as for lowerd trucks, beastmode when his bars were on did scrape a few times at the height there were at. just a thought

 

that is not the correct function of that setup, what your describing is a ladder bar

 

can you give a short discription of how ladder bars work..some thing in english and not calculus
