Yj Frame Dimensions

Ive searched and searched and cant locate the dimensions to the rear part of the frame. Have a buddy thats going to fix my frame rot around my rear shackles. Does anyone know dimensions? Plan on cutting a bit off after making a new piece and welding it up.

Here you go. This drawing was very helpful when I was rebuilding the rear section of my YJ frame.

If you mean the angles of the rear axle hump, maybe this will help. This is how I built the frame rails.



The finished product, prior to priming and paint. I took some design liberties with regard to the shape of the crossmember in front of the gas tank.

Have you thought about making frame repair parts?

No, but if I ever lose my day job, I might consider it.

Copperhead, what size square stock did you use to fix the rear of the frame? 2x3 or is that 2x4? Also what thickness did you go with? Gotta fix my YJ in the next couple weekends.

I PM'ed you, but I'll repeat it here. I used 4" x 2.5", with 1/8" wall thickness. This size is a perfect match to the YJ frame rails.

Thanks! That fit over the frame? Or did it butt up against it?

The frame measures 4" x 2-1/2", so it butts up to it.
