After supercharging my Jeep I’ve had tons of belt issues. Both my idler pulley and tensioner pulley had melted. A stock replacement for the idler had melted a second time and the new tensioner couldn’t have been far behind. At the recommendation of my builder, I ordered and installed the ARS pulleys. Nearly 1000 miles in, the serpentine still looks new. Now, not only do I not have to worry about the billet pulleys melting, I have confidence that my belts will stand up to the rigors of my setup.Kevin C
The tensioner I bought and put on my 2012 Charger RT this past weekend at Maple Grove during the MSHS race worked flawlessly. The car performed great all day. Installation was easy. Drove home 6 hours the next day. No issues and even less belt noise. Great looking tensioner. I am very pleased with the tensioner. Thanks for your support of the MSHS series.
I wanted to let you know we have installed the two street versions of your Hemi tensioner and they are working great!

I purchased the Hemi belt tensioner at the MSHS race at maple grove.
This past weekend at the MSHS race at VMP I took the Bracket class win.
The car was extremely hot and the tensioner performed flawlessly.
Thanks for the great product.
Wanted to let you know tensioner went on today and so far so good. Only took one small washer to line it up. Pics attached of my new belt setup and tensioner.
We will hit track Thursday and will let you know how it goes. Only gonna have 115 degree heat index lol.
Update: Tensioner and new belt setup is doing great. No slip. We still have few more tenths left in the car when the track reopens. Track wasn't great so we didn't spray it much and had a low fuel bog on this run.
