Re: New member from the Black Hills
With my lift, I had to use some shims to set the pinion angle. So when I set up the new rear, I set the perches at the needed angle to not need any shims. If your blazer is not lifted, set the angle same as your original ones were. I also boxed in the ends of my perches, to add some strength, since I have bent them in the past. Ideally your pinion angle should match the angle of your transfer case. Unless you run a cv joint, then the pinion should be the same angle as the driveshaft, minus a couple to allow for axle rotation.
