      (Always verify engine code & pulley layout before service.)

      Handle GM stretch-fit belts the right way. The Oni Tools Double-Sided Stretch Belt Installer services both A/C and main drive pulleys on modern GM trucks. One tool covers GM 5.3L and 6.2L applications (A/C belts on 2014+, main drive belts on 2019+) and the 6.6L gas in HD trucks (2020+). The dual-tab head mirrors the industry-standard pattern—long tab for late-model A/C belts, short tab for main drive—so techs can seat belts and rotate the engine smoothly without prying or risk of nicking a rib. Built from heat-treated steel with a black-oxide finish for durability in shop use, it’s a time-saver for professional installers and a confidence boost for DIY owners. A smart, cost-effective alternative to Lisle 59560, optimized for tight double-pulley stacks on Silverado and Sierra platforms.
