Gates K120903RPM RPM High Performance Micro-V Serpentine Drive Belt - 12-Rib 90.3in

The Gates K120903RPM RPM High Performance Micro-V Serpentine Drive Belt is purpose-built for high-output and forced induction applications where standard belts fall short. Featuring a 12-rib profile and a nominal outside length of 90.3 inches, this belt is engineered to maintain maximum grip and power transfer under the elevated stress of supercharged and turbocharged engine setups.

Key Features:

• Forced Induction Ready: Specifically engineered for supercharged, turbocharged, and high-output engines that demand superior belt performance
• High-Modulus Tensile Cord: Aramid or polyester low-stretch tensile cord construction minimizes belt slip and handles extreme power loads
• Nylon-Fiber Reinforced Undercord: Provides a precision-ground, exact-fit belt profile for consistent rib-to-pulley contact and reduced noise
• Dual Adhesion Gum Layers: Two layers of adhesion gum increase durability and structural integrity under sustained high-load operation
• Reduced Heat, Noise & Vibration: Advanced construction results in lower operating temperatures and quieter performance compared to standard belts
• Exceeds OEM Tolerances: Surpasses strict OEM dimensional tolerances for a reliable, long-lasting fit
• 12-Rib / 90.3-Inch: K-section Micro-V profile with 12 ribs and 90.3 inches nominal outside length

The Gates RPM line is the go-to choice for performance enthusiasts and professional builders running forced induction systems. Whether on a supercharged street car or a built track engine, the K120903RPM delivers the reliability and grip needed to keep accessories and blower drives running at full efficiency.
