3 HA pinion bearing shim for fitting under large bearing cup, using these shims under the bearing cup brings the pinion deeper into mesh, ie it reduces the pinion cone setting.

If you use these shims remember that if you put 0.003" under the cup you will need a 0.003" shim between the pinion small bearing race & the pinion / pinion spacer (we manufacture solid spacers to replace the poor quality collapsible spacer) to keep the turning torque of the pinion the same, between 6 to 12 lbs inch torque.

Available in several thickness's starting at 0.003"
