American Racing Solutions Low Profile Racing Billet Belt Tensioner (9600) - 2011-2026 Ford 5.0L Coyote

Take control of the accessory drive on your supercharged 5.0L Coyote with the American Racing Solutions Low Profile Racing Billet Belt Tensioner. Precision CNC-machined from 6061-T6 billet aluminum, this heavy-duty tensioner is engineered to handle the increased belt loads, horsepower, torque, and RPM found in modified and supercharged Coyote applications.

The factory belt tensioner was designed around factory power levels and can become a weak point as supercharger drive loads increase. The ARS 9600 uses a proprietary high-tension spring, TGP shaft, hardened bushings, and thrust bearings to maintain stronger and more consistent belt control. The result is reduced belt slip for more consistent supercharger boost and dependable power delivery under demanding conditions.

One of the biggest advantages of the 9600 is its low-profile construction. The compact design provides additional damper clearance and is specifically engineered to clear 20% oversized dampers without requiring the tensioner to be ground or modified. It mounts directly in the factory tensioner location for a clean installation without adapter plates.

American Racing Solutions backs the strength of this billet tensioner with a Lifetime Guarantee against bending or breaking, making it an excellent upgrade for serious street, drag racing, and high-horsepower Coyote combinations.

Low-Profile Design for Oversized Dampers

High-performance Coyote combinations frequently use oversized crank dampers to increase supercharger drive speed and boost. Clearance can become an issue with conventional tensioners, sometimes requiring modification to the tensioner body. The ARS 9600 features a purpose-built low-profile design that clears 20% oversized dampers without grinding the tensioner, providing a cleaner solution for modified supercharged combinations.

Improved Belt Control

Supercharger systems place considerably more demand on the belt drive than a naturally aspirated factory configuration. The ARS tensioner's proprietary high-tension spring works with its TGP shaft, hardened bushings, and thrust bearings to maintain belt tension under high-RPM and high-load operation. Improved belt control helps minimize slip that can otherwise cause inconsistent boost and power.

Direct Bolt-On Installation

The ARS Low Profile Coyote Belt Tensioner is designed as a true direct replacement and mounts in the factory tensioner location. No adapter plates are required, allowing the upgraded tensioner to integrate cleanly into compatible Coyote belt-drive systems.

    ARS Tensioner

    Posted by Dax on Jul 14th 2025

    So far, it is doing what it should. Quality seems good, and fitment is as expected. 4 stars instead of 5 because 1- there are no instructions. Having a torque spec for the mounting bolt (its 35 lb-ft), and an understanding of the alignment marks on the tensioner would be nice. 2- The packaging was terrible. For something that costs this much, a decent padded box would have been nice, not just a single sheet of bubble wrap, thrown into a thin cardboard box that can easily be damaged during shipping

    Have the 8 rib kit for the Paxton/vortech kit and git this long after and wish I got it sooner, easily made the biggest power difference out of any mod I done aside from the blower itself. I do recommend using the stock pulley bolt on this tensioner the one provided with the ars tensioner has a small head and it makes the socket want to slip off pretty bad on the install overall very satisfied did not expect it too make such a huge difference in power and boost pressure

    Perfect fit, finish and it's heavy duty. Makes the OEM tensioner feel like a toy.
