Is it OK to jack up the front of my Dart from the center of the K-frame?

Seems like lifting one side at a time (then setting the frame rail on a jack stand) will cause more twisting and stresses on the chassis.

I also asked once before but can't find it with the useless search engine: what about picking up the rear from the center of the 8-3/4"

thanks.

I've jacked up my cars for years center k frame and center rear

^this^

thanks... I've sometimes done this, but always wondered if I shouldn't

The K member is way stronger than it needs to be so absolutely yes.

One side at a time which is way more work than need be but you will not hurt the chassis with this method.

As for the center of the rear axle. Just add care the cup of the jack does not damage the stud and nut of the center section.

I always keep the jack towards the back of the k frame as the k frame is not flat.

I've jacked up my big block 69 dart that way for the past 47 years now, without any issues. I use a block of wood between the jack saddle and the car's k-member.
