I would suspect it to be a Jeep TJ? from your description.
What more than likely has happened is the bb lift was installed without track bar brackets. In the rear, you should have installed a riser bracket off the axle. The bracket basically recenters the rear axle under the frame. In the front, the bracket on the axle is redrilled 3/4" over to bring the axle more centered under the frame. The track bar is to maintain the axle under the frame since it is a specific length. Any height difference between the axle and frame pushes or pulls the axle off center from the frame from the track bar.
So I doubt the frame is bent and the track bar bracket was not installed. Rather than look for a riser bracket that wasn't installed, look to install an adjustable front and rear track bars.
