I would wonder if your spacers have shifted? If the spring mount at one end is out of true then it would probably cause them to bend like this.

Suspension geometry.  I think from the pictures that you havn't fitted any sort of castor correction to the front so when liftes the front axle has rolled forward, this carries the spring seat foreward and tilts it too, roughly 3degrees for every 2" of lift.  Having fitted spring spacers at the axle end only makes this even more noticable.

At the back the long/short arm geometry serves to tilt the diff nose upwards as you lift the car, again the axle has rolled but this time backwards, again made more noticeable by the spacers lifting the spring seat away form the axle.

The front could be cured with castor correction, the back by shimming the lower trailing arms at the chassi end or buying cranked arms to suite the lift.
