TR50 GM Truck Billet Racing Belt Tensioner – 50 lb Spring
Our TR50 Racing Belt Tensioner is CNC-machined from 6061-T6 billet aluminum and engineered for high-horsepower GM trucks and SUVs. It features a custom 50 lb spring, hardened steel shaft, and premium bearings for consistent belt tension under extreme loads.
This is a direct bolt-on replacement designed to reduce belt slip, increase boost consistency, and deliver more reliable power on the street or the track. Built so strong it won’t bend, flex, or break under the heavy loads of modern supercharged and high-performance GM applications.
