This is the Large Roller Design .321" Diameter of Inside Sprag Race.
Often called the black sprag type ; which is the preferred style for most professional rebuilders.

In 2001 GM Went to a smaller roller sprag design.
If yours has failed we suggest going back to this design as the larger elements on the sprag ;
seem to hold up much better than the late model type due to the diameter of the rollers.
* If you prefer the late small roller sprag we do have some of those also;
you can make a special request within the order notes field *


This kit comes with everything shown in the photos.
This package does not include clutch friction clutch plates, but also available in our friction modules # 34119 _ _
This Package Will Include Tumbled Reconditioned Steel Plates, Pressure Plates, And Snap Rings - Not Shown
We also offer nearly all of the components of this kit separately as well.
