Construction & Design

The Perrin Lightweight Crank Pulley is crafted from high-grade CNC aluminum, ensuring both strength and weight savings. The machining process guarantees exact dimensions that match or exceed OEM specifications, providing a perfect fit without compromising engine reliability. The anodized black finish not only enhances corrosion resistance but also adds a refined aesthetic touch under the hood.

By reducing the mass of the crank pulley, this component decreases the rotational inertia on the crankshaft, allowing the engine to rev more freely and respond more quickly to throttle inputs. The design maintains the structural integrity required to withstand the stresses of daily driving and spirited performance use.

Performance & Sound

Reducing the weight of the crank pulley directly impacts engine performance by lowering parasitic drag on the crankshaft. This results in improved throttle response and a slight increase in available power, especially noticeable during rapid acceleration and gear changes. While the pulley does not alter exhaust sound, the enhanced engine responsiveness contributes to a more engaging driving experience.

Installation & Fitment

The Perrin Lightweight Crank Pulley is a direct replacement for the factory pulley on applicable Toyota GR86 and Subaru BRZ 2.4L models from 2013 to 2026. Installation requires basic mechanical skills and common hand tools. No modifications to the engine or accessory belts are necessary, ensuring a straightforward bolt-on upgrade. It is recommended to follow the included instructions carefully and torque all fasteners to manufacturer specifications.
