No. If you think your ride height has changed then you most likely have the u-bolts that go through the bushings tightened too much. If the u-bolts are over tightened it does not allow the sway bar to rotate in the bushings which binds up the rear suspension. This will cause a ride height change and also poor launch performance with no weight transfer.
With the end links disconnected you should be able to forcibly rotate the sway bar by hand.
