As long as you are progressing with the big 3 (bench, squat, deads) your whole body will grow and any strength disparities will work themselves out. The 5x5 program is outstanding with increasing overall strength so as long as you progress keep with it.
Some other exercises include: dumbell bent-over rows, lat pull-downs, seated cable row, reverse hypers and several others. But without more information on yourself regarding routine and diet I kind of hesitate to give any more advice since I just don't know enough about you yet.
However, give up the info and everyone on the board will be willing to help you out.
