This set of Sonnax clutch hub shims 28304-30 allows end play of the high clutch hub to be reduced and controlled in GM Powerglide® units. Limiting hub end play is beneficial when optimizing the high clutch pack stack-up.

The Sonnax shim fits between the small wear plate and drum to lift the hub out of the drum. This reduces end play between the hub and sun gear flange and also maximizes clutch tooth engagement with the hub splines, preventing the rear clutch friction disc from dropping off the clutch hub.

The shim also can be used when a clutch drum has been resurfaced at the small wear plate contact area. The package includes three .032" thick shims which can be combined for additional stack height.

  • Allows hub end play adjustment with a mix of various forward clutch components
  • Includes three shims
