a factory type strut rod is basically mounted solid front and rear.not very condusive for front end rise,the heim ends on the front of the RMS rodsallow the car to rise freely in the front and rotate to the rear wheels.if you want to make mopar rear suspensions work you must concentrate on the front also.the magnumforce upper control arms with rod ends helps even more.once you jack a Chrysler up with stock strut rods and upper control arms then switch to the others you would see a huge difference as to how easily you get separation of the suspension which lets the front end rise and you get weight transfer
