It's a combination of lift and caster correction that puts the pinion angle where a cv shaft is needed to reduce/eliminate vibration.
ok, so it there a "typical" height of lift that these come into play?
Im asking because my lift install is just around the corner. 2.5 OME. I havent decided on bushings or plates yet to address the caster.
Just wondering if I will see a smoother ride with these drive shafts?
