Be careful, do a search. Some have been known to rub thru the tensioner leaving chunks running around inside engine.
My opinion if it needs a tensioner, it needs more than that. I dont believe it will help with timing either. That side is always tight.
It is the loose side, passenger side that gets the tensioner or guide. Keeps the timing chain from trying to go round on the slack side coming off the crank timing gear. Centrifugal force without the guide/tensioner exacerbates stretch.
A good true roller will not wear or stretch as much as the stock "silent" chains. Anything over 30k miles in the days before the guides was basically timing chain time to get a good tuneup. Without you had "spark scatter" where the loose chain allowed the cam to advance and retard.
