The pinon angle has to be the same as your trans output shaft angle for a comfortable trouble free street aplication. If you have trailering arms and used shorter 4" springs to lower then a 1 or 2 deg. wedge should be enough to compansate if you have done no other mods to the trans crossmember. The best way to know for shure is to measure the angles with a degree finder.
