Steel shims to go between your leaf springs and your spring perch. These are used on leaf spring vehicles in order to adjust pinion angles and achieve proper drive line geometry. Our shims are 2.5" wide, machined from steel, and include a new set of 3/8" diameter center bolts. Select size (in degrees).
Use the calculator below to determine the right size shims. The shim calculator figures out the current joint angle, takes into account how much the drive shaft slope changes as a result of the shim, and aims to achieve a 2-3 degree net joint angle. The calculator is only for double cardan rear drive shafts. If you have something else or if you have questions, give us a call. 801-737-0757
Great company with excellent products and great customer service
Worked perfect shipping was fast
Worked as plan, quick delivery, easy install. Thank you.
The axle shims I received were 3 degrees instead of the 5 degrees I ordered. After calling Woody's Josh was quick to assist and sent out a pair of the 5 degree shims. I just got the correct shims in the mail the other day, although they were the right size this time they won't fit my Tacoma without being shaved down, as they are about 5/16 `` to wide to fit between the u-bolts. I cut them down using a metal chop saw no problems. However it would have been good not to have to modify them at all. The overall quality of the shims seems very good, other than having to cut down the width, it wouldn't be a bad idea to include a angle cut washer or a slight angle counter bore for the center bolt, so the head sits flush against the shim.
Great shims. Did exactly what I needed them to.
