Clutch Masters Hydraulic Release Bearing 04-21 STI | Softer Pedal Feel | Hydraulic Clutch Component
Overview
The Clutch Masters Hydraulic Release Bearing is a high-performance upgrade designed specifically for Subaru WRX STI models from 2004 to 2021. This hydraulic bearing replaces the traditional mechanical clutch release mechanism, providing a more refined and consistent clutch engagement. It is engineered to work seamlessly with Clutch Masters FX725 or FX850 push-style clutch setups, making it an ideal choice for enthusiasts seeking improved pedal feel and drivetrain smoothness.
Crafted with precision, this hydraulic release bearing features an aluminum housing and piston combined with a high-speed roller bearing and steel braided lines. This design reduces the number of moving parts compared to conventional clutch forks and release bearings, eliminating the pivot ball that typically wears out over time. Clutch Masters’ engineering approach focuses on durability and performance, ensuring reliable operation under demanding driving conditions.
For Subaru owners, upgrading to a hydraulic release bearing translates to a softer, more consistent pedal feel and reduced shock to the drivetrain during clutch engagement. This results in smoother shifts and less wear on transmission components, enhancing both daily driving comfort and track performance. The hydraulic system’s consistent pressure delivery supports precise clutch modulation, a key benefit for WRX STI drivers who demand both performance and reliability.
