adjustable tracking arm - - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have heard a bunch of people on this site say if you lower your truck, you need to put on an adjustable tracking arm. Is there a reason? I am lowering the rear 4" and was going to use the stock tracking arm. Will this cause a problem?

Just crawl under there, and visualize what will happen if you move the frame 4 inches closer to your rear without shortening the panhard bar. (It pushes the rear off center in relation to the rest of the driveline...)

At stock ride height the track bar is running pretty much level. The more you lower your truck, the track bar angles more which pulls the rear axle to the driver-side, which would cause your truck to 'dog walk' down the road.
My truck was lowered 5 inches with stock trackbar and it wasn't that noticeable, but when I lowered it another 2 inches I put in an adjustable track bar to keep the rear axle centered.
You might be ok with only a 4 inch drop and stock track bar.
