They put my Diff in almost perfect alignment with the drive shaft. I did have to ream the alignment pin hole out a little and we will have to see how long the aluminum holds up with Illinois winter and all the road salt. But all in all in all I am happy with them.

Poor fit on most leaf springs as the shims are very narrow and will not nest properly.

Good quality product!
It's a great product to get your pinion angle right!i played with ladder bars and the best result i had was using pinion shims and floating traction bars above the leaf.Best results compared to 4 link.I'm using this formula on a modified AMRA mud-truck .

As advertised - simple solution
Worked well! No more vibration at 80.

The driveshaft vibration eliminator!!!!!
I used this 4 degree shim to correct the drive line angles of my jeep, and let me tell you, it helped it out a lot. It reduces the un-necessary wear of the u-jonts and gives them more life.

Good price and selection!
This time it is more the vendor (4 Wheel Parts)
then the part that makes the difference. They carry a good selection and have good people to help you make the selection. It is a "Total Package"

6 Degree Axle Shims are Great
This is a great product, it completely stopped the axle wrap I was fighting. It was an easy install, and corrected the drive shaft angle.

For Caster Angle or Driveshaft Angle
Interested in seeing how the aluminum wears over time compared to iron. I needed to correct the front Caster angle after a 4.5 inch(SUA)lift. But could also see it being used for Drive Shaft Pinion Angle alignment.
