Description If you’re running a Magnuson MP112 supercharger on your GM Truck, Pontiac GTO, or Cadillac CTS-V, keeping your belt tension in check is critical. The Magnuson MP112 Tensioner is a direct replacement that ensures your supercharger stays under proper load and delivers consistent boost. Over time, stock tensioners can wear out or lose tension, especially under high-performance conditions. This leads to belt slip, inconsistent boost levels, poor throttle response, and premature belt wear. The Magnuson MP112 Tensioner solves that problem by delivering firm, reliable belt pressure—even under load—so your supercharger performs exactly how it should. This tensioner is specifically designed for applications using the MP112 supercharger. It fits GM Trucks, the Pontiac GTO, and the CTS-V equipped with this system. It’s engineered to OEM standards with durability in mind, making it a smart choice whether you’re doing preventative maintenance or chasing more horsepower. Installation is simple. This is a direct bolt-on part, requiring no modifications. Swap out your old, worn tensioner and enjoy the immediate benefits of improved belt grip, smoother throttle response, and more reliable power delivery. If you’re upgrading your pulley size, turning up boost, or simply keeping your system running at its best, this tensioner is a must-have. Backed by Magnuson’s reputation for quality and performance, it’s built to take the heat and stress of demanding driving conditions. Key Features: Maintains proper belt tension Reduces belt slip under boost Improves throttle response and reliability Direct-fit replacement—no mods required Designed for MP112 systems on GM Truck, GTO, and CTS-V Built to handle high-stress, high-performance use Don’t let a weak tensioner hold back your setup.
