The Honda S2000 suffers from an extremely weak timing chain tensioner. Stock vehicles have experienced noise and rattle from the TCT after 40k miles or even sooner. This faulty piece from Honda also makes it impossible to run high lift cam shafts or run forced induction without experiencing TCT failure. Our heavy duty TCT eliminates all of this. The S2000 are no longer subject to embarrassing ticking noise or limited to low horse power gains from a weak TCT. Ballade Sports Heavy Duty S2000 timing chain tensioners are brand new, not re-manufactured units.
