M6 Primary Chain Tensioner makes a smoother ride by
reducing annoying vibration, keeping constant and
correct tension at all times. Eliminate the worry of your stock tensioner OVER tightening. Your transmission will
'click' into gear instead of 'clunk'. It also improves
shifting performance while extending the life of your
primary chain. Makes it easier to find neutral. Easy installation (generally
less than 1 hour for the non-mechanic), it's not necessary
to remove your chain.
