Can-Am X3 2018 to 2021 closed deck cylinder and bigger stud machine work
Reasons for doing Closed deck
With increased boost and HP you increase the cylinder pressure. The factory block is a open deck and has no support at the top of the cylinder. Therefore it can expand and move around under the head gasket with no support, resulting in a blown head gasket.
Tested at 75 PSIa
Maintains factory coolant temperature.
We CNC mill the block to accept our Closed Deck supports.
Bigger head studs
We upgrade them to 7/16 (11.11 mm) studs that can be reused. The factory head bolts are 9mm and are not reusable.
We bore and thread mill the new 7/16 (11.11mm) threads into the block for a perfect tight fit.
The 7/16 studs torque down to 90 ftlb that’s double the holding force compared to the factory bolts.
The factory head bolt torque is 15 ftlb +150 Degrees that equals about 45 to 50 ftlb
