Tensioner Support Plate
Fits Lightning & HD F150, 2003-2004 Mustang Cobra, 2005 and Newer 3V Mustang
An Original Metco Motorsports Design!
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, allowing the belt to slip. Adding boost with custom pulleys or adding an aftermarket supercharger to your vehicle loads the belt further, compounding the flex 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 stainless steel cap screws with washers (not shown). Please note that longer bolts are necessary to use this support plate with our double-bearing tensioner pulley in Cobra applications, and this plate cannot be used with our tensioner pulley in Lightning applications due to interference with the truck's mechanical fan.
This item is also available in a machined (silver) finish, as shown in image 4. Please choose your preferred finish from the drop-down menu below.
Note 1: This tensioner plate cannot be used with the single bolt tensioner found on the 5.0 4V and the 5.4 4V application.
Note 2: This item is identical to the MTP0001, listed elsewhere on our site.
