Torque Solution Lightweight Crank Pulley

2013–2016 Scion FR-S, 2013–2020 Subaru BRZ, 2017–2020 Toyota 86

Part #: TS-FRS-002

Overview

The Torque Solution Lightweight Crank Pulley is a precision-engineered upgrade designed for the Scion FR-S, Subaru BRZ, and Toyota 86 models within the specified year ranges. This high-quality aftermarket pulley replaces the factory crank pulley with a lighter, stronger alternative that enhances engine responsiveness and overall performance. Ideal for enthusiasts seeking improved throttle response and acceleration without compromising reliability, this pulley is a direct-fit solution that maintains OEM standards while delivering measurable benefits.

By reducing rotational mass on the crankshaft, the Torque Solution pulley allows the engine to rev more freely, translating to quicker throttle inputs and a more engaging driving experience. It is a popular choice for street performance upgrades and track applications alike.

Key Features

Engineered to exceed OEM quality, the Torque Solution Lightweight Crank Pulley offers several key advantages:

• Constructed from durable 6061-T6 billet aluminum for optimal strength-to-weight ratio
• Approximately 597 grams in weight, making it about 3.5 pounds lighter than the original pulley
• Black anodized finish that protects against corrosion and preserves a sleek appearance
• Increased mounting surface area between pulley and crankshaft to prevent loosening or slippage
• Improves throttle response and acceleration by reducing rotational inertia
• Precision CNC machining ensures perfect fitment and balance
• Lifetime warranty backed by Torque Solution’s commitment to quality
• Manufactured in the USA to stringent quality standards

Construction & Design

The Torque Solution crank pulley is crafted from premium 6061-T6 billet aluminum, a material known for its excellent strength, durability, and lightweight properties. CNC machining processes guarantee tight tolerances and a flawless finish, ensuring the pulley fits securely and functions flawlessly with the factory crankshaft. The black anodized coating not only enhances corrosion resistance but also provides a refined aesthetic that complements the engine bay.

A standout design feature is the enlarged mounting surface area between the pulley and crankshaft. This innovation distributes the load more evenly, effectively eliminating the risk of the pulley spinning loose under high-stress conditions, which can be a concern with some aftermarket alternatives.

Performance & Sound

By reducing the weight of the crank pulley by approximately 3.5 pounds compared to the OEM part, this lightweight pulley decreases rotational mass on the crankshaft. This reduction allows the engine to accelerate more quickly, improving throttle response and delivering a more immediate power delivery feel. While the pulley does not directly alter exhaust sound, the enhanced engine responsiveness can contribute to a more dynamic driving sensation overall.

Installation & Fitment

The Torque Solution Lightweight Crank Pulley is designed as a direct replacement for the factory pulley on the 2013–2016 Scion FR-S, 2013–2020 Subaru BRZ, and 2017–2020 Toyota 86 models. Installation requires standard hand tools and basic mechanical knowledge. No modifications to the engine or accessories are necessary, making it a straightforward upgrade for enthusiasts and professional installers alike.

Torque Solution recommends following factory torque specifications and installation procedures to ensure proper fitment and performance.
