Yup....I have put them on most vehicles I have owned. Every little bit helps.

Make sure that they double check the application.
I ordered the exact set. On the box it said it would fit V6's & BBC's. (?)
They don't fit the V6. At least the ones that they sent me didn't. Bottom one is way outa alignment with the rest of the pulley system.
By the time I figured that out, I'd had 'em too long on the shelf to send back.
So...if any one wants some for a Vortec BBC...

Meh for what your getting it's kind of over priced also they do not add horsepower if anything they free up what's already there
