ICT Billet Idler Pulleys Editorial Review
The ICT Billet AC Delco LT Truck Belt Tensioner Idler Kit has received overwhelmingly positive feedback from users who own 2019 and newer Silverado trucks and SUVs. Customers have expressed relief at moving away from the factory-installed stretch belts, which are often seen as impractical and difficult to manage. Many users appreciate the ease of installation, with several reports of completing the process in as little as 15 to 30 minutes. Users have noted that the product operates smoothly and quietly, significantly reducing or eliminating annoying belt squeals commonly associated with the stock belts. However, some customers pointed out a few drawbacks, including the need to carefully read the installation instructions to ensure proper pulley swapping. Additionally, the kit's recommendation for a 74-inch belt was found to be inaccurate, with many suggesting a 75-inch belt instead – specifically the Continental 4060750 as a suitable choice. Furthermore, some users identified a lack of torque specifications in the provided instructions, leading them to Consult their service manuals for this necessary detail. Overall, the transition to this kit has been described as a worthwhile investment that simplifies maintenance in the long run, making it a desirable upgrade for the targeted Chevrolet Silverado models. **
