Tomioka Racing Lightweight Crankshaft Pulley - 2012-2026 Subaru WRX / 2011-2024 Forester / 2019-2024 Ascent / 2013-2026 BRZ / Legacy / Outback / Crosstrek / 2013-2016 Scion FR-S / 2017-2020 Toyota 86 / 2022-2026 GR86

The Tomioka Racing Lightweight Crankshaft Pulley cuts factory crank pulley weight by over 60% across a wide range of Subaru, Scion, Toyota, and GR86 platforms -- billet aluminum, gold anodized, 100% bolt-on.

Over 60% Weight Reduction in Gold Anodized Billet Aluminum

CNC machined from lightweight billet aluminum with a gold anodized finish, the Tomioka Racing Lightweight Crankshaft Pulley reduces the rotational mass the engine must spin at the crank by over 60% compared to the factory unit. The reduction in rotating mass allows the engine to rev more freely and respond more quickly to throttle inputs. Dyno testing on a 2013 Subaru BRZ showed a 10 WHP gain from the full lightweight pulley set.

Broad Platform Coverage, Simple Installation

This pulley covers an unusually wide range of Subaru FA-series engines across the WRX (2012+), Forester, Ascent, BRZ, Legacy, Outback, Crosstrek, Scion FR-S, Toyota 86, and GR86. Direct bolt-on replacement for the factory crank pulley with no modifications required. Compatible with stock and most aftermarket belt configurations.

Straight From Subispeed

The crankshaft pulley delivers the most noticeable improvement of the three lightweight pulley positions -- the crank carries the most mass and rotates at engine speed. The 60%+ weight reduction translates directly into a more willing, free-revving engine character. Pair with the Tomioka lightweight alternator and water pump pulleys for the complete package.
