About this item

  • Precisely adjust clearance between the input shaft and 3-4 synchronizer assembly with these shims.
  • For accurate spacing, choose materials such as steel which are hard enough to resist scratching and deforming.
  • Softer shims, like copper or aluminum, are typically used as wear plates between components that rub together, preventing damage to equipment.
  • Carbon steel shims have excellent strength, but aren't as corrosion resistant as other shims.

These shims are perfect to adjust the input shaft end clearance to the main shaft. They fit on the input shaft perfectly and come in several different thicknesses so you can get the end play right where you want it. I set my input shaft to main shaft at around 16 thousands with 25 thousands being the maximum.
