(7 reviews) Write a Review
Frequently bought together:


Chrome Piston Rings for Kohler K161 and 181 Engines with a bore size of 2.938". These fit Type "A" pistons.

Same High Quality Piston Rings we use to rebuild dozens of tractors per year! 


  • Kohler 232575S 
  • Kohler 232575 

Note: Some tractors such as the Cub Cadet "Original", Cub Cadet 70, Cub Cadet 71 have what is known as a K161 "Small Bore" which is a K160 6.6HP Engine with a bore size of 2.875". These rings will NOT fit that engine.

    Good rings for iSaveTractors Pistons ONLY

    Posted by Paul on May 5th 2020

    These rings work just fine for the iSaveTractors aftermarket pistons. However, these rings will NOT fit the Kohler / Mahle original piston.
