2008–2015 Scion xB2 2AZ-FE (TRD Supercharged)

K070896RPM-xB

Overview:

The Gates Performance Micro-V Serpentine Belt is engineered specifically for the TRD supercharged Scion xB models produced between 2008 and 2015. Designed to replace the original equipment belt, this high-quality serpentine belt delivers enhanced durability and superior performance under demanding conditions. Ideal for enthusiasts and daily drivers alike, it ensures reliable power transmission to engine accessories while withstanding the increased stresses of forced induction setups.

With its truncated design, the Gates Micro-V belt offers improved flexibility and reduced heat buildup, allowing it to operate efficiently at higher speeds on smaller diameter pulleys. This makes it an excellent upgrade for TRD supercharged Scion xB owners seeking a belt that can handle the rigors of enhanced engine output without compromising longevity.

Key Features:

Gates Micro-V belts incorporate advanced technology to outperform standard V ribbed belts. Key features include:

• Exclusive truncated belt design providing up to 80% higher horsepower capacity than Rubber Manufacturers Association (RMA) standards
• Increased flexibility and reduced heat buildup for operation at extra high speeds on smaller diameter sheaves
• Exceptional resistance to oil, heat, and other adverse environmental conditions
• Less sensitivity to debris in the sheave groove, reducing the risk of belt damage
• Meets or exceeds RMA standards for static conductivity, ensuring safe and reliable operation
• Energy-efficient design that runs cooler than conventional belts, contributing to longer service life
• Specially engineered to prevent belt bottoming in the sheave, enhancing smoothness and durability

Construction & Design:

The Gates Performance Micro-V Serpentine Belt features a truncated profile that shortens the belt length compared to traditional V ribbed belts. This design innovation increases the belt’s flexibility and reduces heat generation during operation, which is critical for high-speed accessory drives found in supercharged engines. The belt is constructed from premium materials that resist oil contamination and thermal degradation, ensuring consistent performance even in harsh engine environments.

Its smooth-running characteristics minimize vibration and noise, while the robust build quality ensures it withstands the increased loads associated with the TRD supercharger system on the Scion xB. This belt is engineered to maintain optimal tension and grip, preventing slippage and premature wear.

Installation & Fitment:

The Gates Performance Micro-V Serpentine Belt is designed as a direct replacement for the factory belt on 2008–2015 Scion xB2 models equipped with the TRD supercharger and the 2AZ-FE engine. Installation requires no modifications, making it a straightforward upgrade for technicians and enthusiasts. Proper routing and tensioning according to manufacturer specifications will ensure optimal belt life and accessory performance.
