Metco Tensioner Support Plate

Fits Lightning & HD F150, 2003-2004 Mustang Cobra, 2005 and Newer 3V Mustang

This billet aluminum plate was designed as a solution to the problem of the factory Ford belt tensioner deflecting under load in supercharged applications.  The factory tensioner arm tends to flex toward the front of the vehicle under heavy belt loads, and adding boost with custom pulleys or adding an aftermarket supercharger to your vehicle compounds the problem.  

This brace is CNC-machined from 6061-T6 aluminum and is then finish-anodized in black for long-lasting surface protection.  The brace simply bolts over the factory tensioner using the provided longer bolts, and when installed, prevents the tensioner from bending outward.  A special Delrin insert is installed in the back of the brace to prevent metal-to-metal contact when the tensioner is heavily-loaded.

The kit is a complete bolt-on, and requires no cutting, drilling, or any irreversible changes for installation.  The kit includes the precision-machined billet plate with the Delrin insert, three aluminum spacers, and three Grade 8 cap screws with washers.

Stop your OEM belt tensioner bracket from bending with Steeda's new Tensioner kit! A major problem with Supercharged applications as the increased belt length and tension puts unwanted stress on the factory tensioner. A real problem is when you kick the clutch and pull the next gear the RPMS suddenly drop.

With the extra rotating mass of the supercharger and weight of all the accessories it will jerk the belt and sometimes hurt your OEM tensioner. It causes it to flex and in the end you usually end up with broken belts that are hard to find and expensive. A great fix for all blown Roush, Saleen and other bolt on supercharger applications. Kit is available with a factory pulley or an optional billet one.

Note: 555-3358 is designed for use with Whipple supercharger kits with a 3.625" - 3.25 blower pulley. These kits require a 90mm idler.
