Stretch-Fit Technology and Fit

Gates uses exclusive self-tensioning technology that helps the belt adapt to unique stretch-fit drive setups. The design aims to fit like a glove, reducing guesswork during installation and helping to ensure proper engagement across the drive system.

• Exclusive self-tensioning helps maintain correct belt tension on stretch-fit systems.
• Designed to cover the growing stretch-fit belt market as vehicle designs evolve.

In daily use, a belt built to stay engaged under varying engine loads can contribute to steadier operation of the alternator, A/C compressor, water pump, and power steering pump, supporting a smoother driving experience.

• Compatibility with Ford and Lincoln 3.3–3.7L engines using Micro-V stretch-fit belts.
• Durable construction aimed at longer wear in typical road conditions.

Gates continues to expand coverage for stretch-fit Micro-V belts, aligning with evolving engine bays and a growing number of vehicles relying on this design for their accessory drives.
