didnt see any instruction in the box,my ring where both .010 top and bottom be sure to check and gap them before installing, kit pretty straight forward but instruction would be helpful for people that dont build motor or have never have… if you experience or have common understanding its pretty simple.. stock head nuts get 18 foot pounds of torque but stock head studs suck very flex able who kit took took about hour and half for me to tear down and set ring and reinstall.. i suggest heavy studs but not need ive reuse the stock on few kits but peace of mine as one stud would never allow full 18 foot pounds as was twisting so i stopped at 16 foot pounds that stud has held for 1800 miles… so far at the moment only one company carry heavy duty studs.. other then that total suggest go all out and get big bang for buck and 186 kit is it… highly suggest oil cooler aswell

I put this 186 kit on my 2020 monkey. It’s fast as fuk. Lots of torque. Way more fun to ride now. You need this kit on your monkey.

This is good. Real good, the cooler I got was different than pictured but that’s okay it worked out just fine.
