Not that I know of.. you can maybe buy a steel version.. But in all honesty just buy a Thump unit.
I've had a stock replacement 3 bolt tensioner from Napa on my car for 3 years. I've also had the same Napa (gates) belt on my car for the same 3 years. I've never had ANY issues and I'm making 22-24psi with a YSI. I personally think the "billet" tensioners are over rated. no saying they don't work, but I've never seen the need for one on my 700RWHP 20+psi car.....
