Yes. If you rotated your pinion up for a CV rear driveshaft, you rotated your shock mounts down (and closer to the rocks). Which now further extended your rear shocks, and now limits your available down/extension travel. And brings your shock body closer to the rear axle tube. That's why folks use these brackets. I originally used the Tera-Flex brackets when I did my Jeep's suspension.
One day I crunched the driver's side rear lower shock mount on a rock. So we cut the rear lower shock mounts off, and welded on new ones that positioned the shock mount up higher (almost level with the bottom of the axle tube). Now my shocks were more compressed, and I had very little upward movement before they were fully compressed. So replacement shocks were in order. Even though my Jeep has essentially a 4" lift, I have to pay attention to the extended/compressed measurements of the rear shock before I buy them. I recently replaced my Bilstein 5100 series shocks with Rancho RS5000X shocks, and the rears are for a TJ with a 2.5" lift.
There's always a trade-off.
