KM178 Pump & Drum Update Kit
Matched Reconditioned Part - Updated Bearing Design
As A Set This Will Drop In Place For The Bushing Type
These Pump Stators Are Well Known For Carrying The Weight Of Most Of The Drivertrain.
In Doing So The Stator Support Will Ring Groove Out The Bore If The Drums.
KM Attempted To Help This And Reduce Strain By Going With The Needle Bearing,
But With Enough Miles We See All Styles Of These Become A Weak Point In This Transmission Type.

Vehicle Applications This Design Will Fit 2000 Up

At Times Will May Have The Bushing Style In Stock Also; Which Sells For About 25% Less
