New Release 2023 V3 GZR Billet Bottom End kit this by far the most diversified Billet crankcase on the market hands down. this crankcase you can put any marine style coil RCMK/TigerKing/zenoah/Rev/ and other clones, also you can buy with our New 1 pcs coil setup that's right only 1 coil thats it. You don't have to worry about chasing which coil is going bad, With this setup you do not have to worry these coils hardly ever go out and if it does you can change it while it is in the boat No better setup out there nowhere.The zenoah 320 type coil is not the same as this coil and will not fit.

The 2020 V2 billet crankcase is not like any others ever on the market it only weights 11 grams more then a zenoah case.It also will seal a tapered crank with the internal seal between the inner and outer bearing so it will seal any marine crank on the market. the V2 case is nothing like the V1 case it took us months laying this out and testing and this is not a easy task at all.so this is what you get.
