12 bolt cover with bearing supports - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is a diff cover that has the extra carrier bearing support preloads useful on these truck rearends? I'll be running about 400rwhp with 4.11 gears and ET streets (probably 28" tall).

So is it worth it, or would it be just a waste of money?

The preload diff. covers are good if your going to put enough power to the rearend that it will bust apart. plus they also look killer. Here the cover on my 70 camaro.
