    It’s my understanding that most of the time when crankshafts are replaced it’s because the keyway has gotten stretched out or damaged.
    And since these are billet cranks, I’ve very rarely heard of people braking cranks, so has anyone ever just had on re-keyed?

    I just had one re-keyed and plan on using it so I’ll let you know how it works out for us but I thought I’d ask if anyone else had experience with doing this.
    We re-keyed it 180 from original keyway.
    We also discussed doing this to the crank and the clutch from day one so it will be double key from the get go.

    key’d cranks breaking are a common thing actually,   always use a crank support that helps,   splined cranks are much stronger but limits your choice of clutches,   re keying a crank would weaken it even more,  I wouldn’t do it
