pfrederi 18,667 #2 Posted November 25, 2020 Do you mean .030 or .003. .003 was used by Kohler, I understand, when a new engine was just a bit out of spec. .030 is a standard oversized used in rebuilds... Share this post Link to post Share on other sites

Here is one source for OEM. http://www.psep.biz/store/kohler_original_equipment_piston_kits.htm You will need to scroll down to find model K301 They also carry aftermarket for the budget minded. http://www.psep.biz/store/kohler_aftermarket_piston_kits.htm If you are in need of the rest of the gasket & seals to install your new piston, you can check the above site for rebuild kits or gasket sets as well.
