    • Question:
      12/2/2022
      What is the compression ratio of these pistons
      Big Dave - New York
      • Answer:
        Hello Big dave, These would make it 11.0:1 but you would need to have allready have the 119 or the 122 engine kit installed as they will not fit a stock engine. These are direct replacement ( they come in the 119 or 122 kits) Gigglesthehelper

    • Question:
      1/27/2021
      I have a 2018 RKS that already has the 114 Stage III kit on it. Can I just replace my pistons with this kit or do I need other parts to complete converting from 114 to 119? Do I have to replace the jugs as well?
      Rabagg04 - Dallas, GA
      • Answer:
        Hello Rabagg04, This kit is a replacement piston kit for 17-later Milwaukee-Eight models equipped with Screamin' Eagle 107CI to 119CI Stage III kits. Thank you, Captain Slow

    • Question:
      9/26/2020
      Do these pistons have the same 2mm oil control ring like the stock 107 piston. Or are they an upgrade to 3mm.
      Rokin - Cedar Rapids Iowa
      • Answer:
        Hello Rokin, The oil rail and rail scraper rings are similar in size when compared to those dimensions but they are not the same. This is a high-strength aluminum forged piston kit. Thanks, shvlhd
    • Question:
      9/22/2020
      I already have a stage 2 with aftermarket lifters, adjustable push rods, zippers 468 cam and tuned with a TTS Mastertune. I’m assuming I could just upgrade to the 119 cylinders, pistons and upgraded oil pump correct?
