Item 49711

Features & Details

  • Eliminates Belt Slippage
  • 6061-T6 Aluminum Construction
  • Black Anodized Finish
  • Simple Installation
  • Fits 2003-2004 SVT Cobra and 2005-2010 GT Mustangs
Eliminate Belt Slippage. The factory tensioner arm tends to flex forward under heavy belt loads which can allow the belt to slip robbing you of horsepower. A Metco Motorsports Tensioner Support Plate prevents the tensioner arm from flexing to stop belt slippage so you can reclaim lost power.

6061-T6 Aluminum Construction. CNC-machined from 6061-T6 aluminum that is completed in a black anodized finish, this Metco Tensioner Support Plate features a special Delrin insert installed on the back side to prevent metal-to-metal contact when the tensioner is heavily-loaded.

Simple Install. The Metco Support Plate simply bolts over the factory tensioner arm using the provided longer bolts for a quick and easy installation.

Application. This Metco Tensioner Support Plate is specifically designed for use on the 2003 to 2004 SVT Cobras equipped with the Supercharged 4.6L V8 engine, as well as the 2005 to 2010 GT Mustangs equipped with the 4.6L modular V8 engine.

          Works great

          Super easy install and no more shredded belts! Kinda pricey for just a billet plate and some screws though.

          Worth It!

          Easy to install, definitely helps control tensioner deflection. Helps keep the belt from getting tore up along the edges

          What you need!

          Metco produces top notch products, and this one is no exception! Adds drastically increased rigidity to the factory blower drive tensioner, no more flexing tensioner and belt shredding that a pullied down Eaton or bigger blower install can cause. A nice alternative to $500 Thumper billet tensioner...

          Great upgrade!

          Decided to get this instead of purchasing a different tensioner. And I must say this part does wonders! No more belt slippage at all! Easy installation! This is a must have for your car especially with Metco under drive upgrade
