Which tensioner should have the heavy duty spring in? The one for the acc belt, sc, or jackshaft.

On my 93 I had two one on the sc and one on the jackshaft. My 95 came with one on the acc belt. Which is right?

ah man, I should have taken the ones from my 93 before i sold it :(.. so the one on my 95 right now on the acc tensioner is not doing anything ?

I have a 10% pulley, would the belt be slipping without one.?

From the factory, the main belt had a heavier spring. The MP heavy duty springs go on the JS and SC tensioners.

IMO if you wanted to upgrade the SC and JS tensioner springs the cheep way, all you would need is the springs out of 2 main tesnioners.
