Gates K120979RPM Rpm High Performance Micro-V Serpentine Drive Belt

The Gates K120979RPM is a RPM® High Performance Micro-V® Serpentine Drive Belt engineered specifically for high-output and forced induction engines. Designed to handle the extreme demands of supercharged and turbocharged applications, this belt delivers reliable power transfer where standard belts fall short.

Key Features:

• High-Modulus, Low-Stretch Aramid Tensile Cord — Resists elongation under the extreme loads generated by superchargers and forced induction setups
• Nylon-Fiber Reinforced Undercord — Provides added strength and resistance to cracking or separation under high-stress conditions
• Advanced Precision-Ground Belt Profile — Exact-fit design ensures optimal contact with pulley grooves for maximum grip and power transmission efficiency
• Dual-Layer Adhesion Gum Construction — Two layers of adhesion gum bond the components for superior strength and long-term durability
• Strict OEM Dimensional Specifications — Drop-in replacement that meets factory tolerances without modification

The Gates RPM® series is the only serpentine belt line specifically developed for high-performance and forced induction engines. Unlike standard serpentine belts, the RPM belt is built to maintain tension and resist slippage even under the dramatically increased accessory drive loads produced by positive-displacement and centrifugal superchargers. It is a trusted choice for performance builds and is used by leading supercharger manufacturers in their performance kits.
