    Supercharger Belt???

    Is there one belt that is better than another? Im doing some work to my ski and while Im in there I wanted to change the belt just as preventative ( ill leave an extra in there too. The ski has 106 hrs its a 2015 310R

    Is OEM ok or is there a better aftermarket belt? I already have installed the grease fitting in the tensioner and the pulley bearing is fine.

    Thank you

    Not sure if the 250/260 ultras are the same as the 310x but
    This is the gates belt# off the shelf at any parts store. I think Gates makes a really good belt.

    6PK845 or 6PK843, two different belts? Thanks for any clarifications.

    That sounds like a REALLY good idea! How/where do you secure the second (unused) belt so that it doesn't get next to anything that's spinning?

    6 = 6 ribs, PK = profile, 843 = length in mm

    Thanks but we are listing two different sizes here. 843 or 845. I really don’t want to put on the wrong length since it would probably work, but if too long it will slip sooner once it wears some or it will have the tensioner maxed travel .
    thanks for all the help.
