frame notching and rear axel allignment??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When doing a frame notch such as insane68's, would you need an adjustable panhard bar to keep the rearend in line? If you put airbags under such a large notch, wouldn't the raising and lowering put the rear out of allignment? i hope this is clear enough. Any ideas?

Yes, if you lowering a truck, you'll need an adjustable panhard bar. Lowering a truck won't cause the rear end to shift out of center any more than a truck at stock height. You just center the rear end at ride height. Actually, with my setup, the panhard bar is close to horizontal at ride height, so the side to side movement will not be much at all.
