High misalignment spacers are designed for suspension joints, steering tie rod ends and anything else that uses the pivot of a spherical bearing such as heim joints, rod ends and uniballs. They have two functions. They reduce the hole size to accommodate a smaller bolt and increase the max angle of a spherical bearing.

How much the angle is increased is determined by the bolt size and the amount of material removed. When more material is removed, the strength of the spacer is decreased. The same happens when using a larger bolt. To compensate for this we only use heat treated 17-4 stainless steel for our spacers. This also prevents corrosion when used in everyday applications.

We offer a wide variety of high misalignment spacers for almost every possible application.

Important Notes:
  • Not all spacers will fit every uniball or heim joint. See diagram below regarding uniballs.
  • The stack height or width in the title of the page is a nominal dimension. See below for actual decimal dimension.
  • Material: 17-4 Heat treated stainless steel
  • (A) Shoulder Height: 0.475"
  • (B) Head Diameter: 1.000"
  • (C) Half The Stack Height: 0.910"
  • Nominal Stack Height: 1-13/16"
  • Actual Stack Height: 1.820"

How to measure misalignment spacers for fk rod ends aurora bearing company and nhbb new hampshire ball bearing

Stack height or stack width, depending on which way you look at it, is an important dimension for you to know for the length of the bolt you'll need plus the gap that you'll need in order to put the rod end or uniball on your vehicle.

We sell the spacers individually because occasionally customers will use two different heights of spacers on one rod end or uniball to achieve the stack height required for their vehicle.

Will Fit:
  • Aurora Bearing Company
  • FK Rod Ends
  • NHBB New Hampshire Ball Bearings
  • RBC Aerospace Bearings

Important Note:
Aurora Bearing Company: PWB12T
FK Rod Ends: WSSX12T
New Hampshire Ball Bearing Company: ABWT12
RBC Aerospace Bearings: MS14102-12

On the above 3/4" uniballs, if you use a high angle misalignment spacer, you must put the spacers in a lathe and change the radius. The radius of the misalignment matches an AIN12T or AIB12T, but on PWB12T, WSSX12T, ABWT12, or MS14102-12 3/4" uniballs, the edge hangs over and will peel out the PTFE liner in your uniball. See below picture.
