The Weistec Engineering M113K Forged Pistons were designed and manufactured to address the weaknesses of the OEM M113K pistons.
Our 2618-T61 forged pistons feature larger ring lands, improved piston dish, skirts, and wristpin mounting while still weighing less than the OEM pistons. Stronger yet lighter 9310 Steel Wrist Pins are included with our forged pistons. Our wrist pins are compatible with the OEM rods as well as any aftermarket rod that is made to OEM dimensions. High quality piston rings designed for the heavy boost that a built M113K engine will experience are included as well.
Each piston comes with ceramic coating on the piston top for added heat resistance and Teflon coating on the skirts to reduce friction. All the key design features of our M113K Forged Pistons come together to result in an engine that can handle high power levels as well as rev more freely and efficiently thanks to significant weight savings on the rotating assembly.
Note: Pistons are designed for stock engine bore diameter. Before purchasing make sure your engine is within spec, read our M113K Piston to Bore Clearnce Guide in the documentation tab.
