Not using a cripple stud on an Interior door frame?

I have a prehung interior door I am going to frame into a basement wall, which is not load bearing.

The door just fits height wise with 3/4" clearance below the top plate, so I can not fit a traditional "header" in.

I was thinking that in this case I didn't need a cripple stud running along side my king stud because it seems redundant to me.

So in this case my "Framing" should simply consist of one 2x4 on either side of the door.

Or am I missing something?

That's what I would do since its not load bearing. Gotta love short basements....

The jack is only to hold up the header, no header no need for it.
I would consider adding an extra 2 X 4's on the two sides to make it easyer to attach the trim.

you want to still add a double on either side of the opening, the king jack combo as used in walls around doors not only holds the header up but provides more solid support to mount the door and trim to than a single stud at either side of the door would.. also, the double gives much more solid nailing surface where the studs land on the plates.

doubling it makes for a stiffer door too..less chance of the jamb shifting

What he said.

If you have a hollow door, you are fine.

If you have a 1 3/4" solid core door, you will want some beef in the wall. It is no unheard of in that instance to have two studs and then the cripple.

A single 2X4 on each side of the door opening is sufficient strength to hold a interior door if sheetrock is installed on both sides of the wall. If you have short pieces of 2X4 left over, they can be nailed to each door stud so you have extra width to nail your door casing to. But this is one of those nice but not necessary items.

Even KD lumber is seldom any drier than the air it is in. whe wood will shrink and bow around every big knot or "wild grain". Two studs will resist warping of the studs better. It's your choice if you want to take the chance for $8.00

Thanks everybody for your replies, you guys on this forum are all great.

In the end I did go with singles on both sides, but on the hinge side which was only 3.5 inches from the end stud. I blocked the end stud to the king stud. in 3 locations. I figured that would help resist warping.

I did this before most of the replies below, were in. It seems the consensus, was to double it up. Had I waited till now and next time I probably will double it up. but what is done is done.

on the details
- Bruntson: I was going to install sheet rock on both sides.
- cleveman: yes the door is hollow
- Duckweather : a stud in my area is ~$5.50
