98 Jeep magnum
The 5.9 Magnum (96 on up) is balanced with the a/t flexplate (already counter weighted) and the stock harmonic balancer. You can run a 273/318/340 torque converter( non weighted), or knock the weights off a LA 360 converter. This is what I did, on my 99 5.9 Magnum, works fine. Nice score!
