ball joint lenghts

[texas pride]

I have a dw11 that I have ran a few times this year and I was recently going through the front end and found my ball joints were different lengths. so im wondering if this what others are running or do I have the wrong bj on my car. lf upper is 1" longer rf upper is 1/2" longer . both lowers are 1" lower. this seems wrong to me. wouldn't I be better off with longer on top. any help would be great.

It has to do with where the chassis builder designed the front roll center to be. What you posted is not uncommon at all
