Gates K040410RPM RPM High Performance Micro-V Serpentine Belt 4-Rib 41-5/8 In.

The Gates K040410RPM RPM High Performance Micro-V Serpentine Drive Belt is purpose-built for the demands of high-output and forced induction engines. Engineered from the ground up as a performance-first serpentine belt, it delivers superior power transmission with reduced heat, noise, vibration, and belt slip compared to standard OEM-style replacements.

Key Features:

• Precision-Ground Belt Profile: Advanced, exact-fit profile is precision ground — not cut — ensuring a perfect pulley seat and optimal engagement
• High-Modulus, Low-Stretch Aramid Cord: Provides exceptional tensile strength and minimal elongation under high-load, high-boost conditions
• Nylon-Fiber Reinforced Undercord: Aramid reinforcement in a patented EPDM compound delivers superior heat resistance and long-term durability
• Dual Adhesion Layers: Two layers of adhesion gum bond the belt construction together for maximum strength and service life
• Strict OEM Dimensional Specifications: Maintains precise fit across a wide range of applications
• Black Finish: 4-rib design with 0.56 in. (14 mm) top width and 41-5/8 in. (1,057 mm) outside circumference

The Gates RPM series is the only serpentine belt line in the industry specifically designed for forced induction and high-performance engines, where stock belts are prone to slipping, stretching, and premature failure under elevated boost pressures. The result is improved power delivery, cooler operation, and unsurpassed boost consistency.
