Enhance Your FA20 Engine with GFB Lightweight Pulleys

Unlock the hidden potential of your Subaru BRZ, Scion FR-S, or Toyota 86 with the Go Fast Bits (GFB) 3-piece lightweight pulley kit. By replacing the heavy factory components with precision-machined aluminum, you effectively reduce the rotating mass attached to your engine. This reduction allows the engine to spin up faster, resulting in noticeably snappier throttle response and improved acceleration throughout the power band.

Precision-Crafted for the Boxer Platform

Constructed from high-quality 6061-T6 aluminum, these pulleys are built to withstand the rigors of high-performance driving while remaining incredibly lightweight. The CNC machining process ensures that every piece fits perfectly, maintaining factory belt alignment and tension for a hassle-free installation process.

  • Optimized Rotating Mass: Faster engine revs and improved power delivery.
  • Durable Construction: 6061-T6 aluminum for long-lasting performance.
  • Direct Fitment: Designed specifically for the FA20 engine platform.
  • No Tuning Required: A true bolt-on performance upgrade.

This kit includes the crank, alternator, and water pump pulleys, providing a comprehensive weight-reduction solution for your vehicle. Compatible with all 2013-2020 Subaru BRZ, 2013-2016 Scion FR-S, and 2017-2020 Toyota 86 models. Experience the difference that reduced rotational inertia makes on your next drive with premium components from GGCRACING.
