you must forgive most of the people around here. i think half of them are kids, and the other half forgot how to help new people.

when i had my jammin i ran it like this from what i can remember.

front
diff 5000
shocks 40 or 35
lower center hole on shock tower and inner hole on arm
springs stock
center
diff 5000
rear
diff 2000
shocks 30 or 25
springs stock
lower center hole on shock tower and inner hole on arm

set axles level for ride hight, front and back

this would be a good start
