Overview:

The Cusco Light Weight Aluminum Pulley Set is a precision-engineered upgrade designed specifically for the Scion FR-S (2013–2016), Toyota 86 (2017–2018), and Subaru BRZ (2013–2018). This pulley set targets enthusiasts looking to reduce rotational mass on their engine’s accessory drive system, resulting in improved throttle response and smoother acceleration. By replacing the heavier factory pulleys with lightweight aluminum components, Cusco helps reduce engine load and enhance overall performance without compromising reliability.

Ideal for drivers who want a subtle yet effective performance enhancement, this pulley set offers a direct bolt-on solution that maintains OEM fitment and function while delivering measurable benefits in engine efficiency and responsiveness.

Key Features:

The Cusco Light Weight Aluminum Pulley Set combines advanced materials and thoughtful design to optimize your vehicle’s engine dynamics. Key features include:

• Set includes three pulleys: Crankshaft, Water Pump, and Alternator for comprehensive accessory drive weight reduction
• Constructed from Cusco’s signature blue anodized lightweight aluminum for durability and corrosion resistance
• Significant weight savings compared to stock pulleys:
• Crankshaft pulley: 790 g (1.74 lbs) vs. 2.3 kg (5.07 lbs) stock
• Water pump pulley: 245 g (0.54 lbs) vs. 500 g (1.11 lbs) stock
• Alternator pulley: 76 g (0.16 lbs) vs. 300 g (0.66 lbs) stock
• Reduces rotational inertia, decreasing engine stress and improving acceleration response
• Maintains factory pulley dimensions and belt compatibility for seamless integration
• Precision CNC machining ensures perfect balance and fitment
• Enhances engine efficiency by lowering parasitic losses from accessory components

Construction & Design:

Cusco utilizes high-grade aluminum alloy for these pulleys, combining lightweight properties with exceptional strength and durability. The pulleys are CNC-machined to exacting tolerances, ensuring optimal balance and smooth operation at high RPMs. The distinctive blue anodized finish not only provides corrosion resistance but also adds a visually appealing touch under the hood. This design approach guarantees long-lasting performance and reliability, even under demanding driving conditions.

Performance & Sound

By reducing the mass of the crankshaft, water pump, and alternator pulleys, this set lowers the rotational inertia of the engine’s accessory drive system. This reduction translates to less engine load, allowing for quicker throttle response and improved acceleration feel. While the pulley set does not directly alter exhaust sound, the enhanced engine responsiveness can contribute to a more engaging driving experience overall.

Installation & Fitment:

The Cusco Light Weight Aluminum Pulley Set is designed for direct replacement of the factory pulleys on the specified models. Installation typically takes about two hours and requires basic hand tools and mechanical knowledge. No modifications to the engine or accessory belts are necessary, ensuring a straightforward upgrade process. Proper torque specifications and alignment should be followed to maintain optimal belt tension and pulley performance.

What's Included:

• One Crankshaft pulley
• One Water Pump pulley
• One Alternator pulley
• Installation instructions
