  • Compatibility: Compatible with Sierra 1500 2014-2018; Yukon XL 2015-2020; Yukon 2015-2020; Sierra 1500 Limited 2019; Tahoe 2016-2019; Suburban 2016-2019; Silverado 1500 2014-2018; Silverado 1500 LD 2019; Escalade ESV 2016-2020; Escalade 2016-2020.
  • OE Reference Number: 90K-39371, 12626059, 12670574.
  • Performance: The new tensioner and belt provide constant, optimal tension, eliminating belt slippage. This means: more powerful air conditioning, more stable alternator charging, more responsive electronic power steering, and more efficient water pump circulation, comprehensively improving the driving experience and safety.
  • Problem: During inspection, fine cracks were found in the belt, and a new one was installed. However, shortly after, the new belt showed abnormal wear or broke, raising suspicions of a substandard belt or a deeper vehicle problem.
  • Solution: Our kit provides a brand-new tensioner that delivers constant, precise tension, and a new idler pulley ensures smooth rotation at all pivot points, completely eliminating any potential sources of failure in this system.
  • Easy Installation: Damaged or old parts can be directly replaced. The installation process involves simple disassembly and alignment, requiring no modifications or adjustments, ensuring system compatibility.
  • Packing list: 1x Serpentine Belt Kits.
