KPower Internal Hydraulic Release Bearing Kit (V2) for 1990-2005 Mazda Miata (NA NB)

The all-new KPower Hydraulic Release Bearing for NA/NB Miata is a complete redesign focused on long-term reliability, simplified installation, and seamless compatibility with stock hydraulics. Available for both 5-speed and 6-speed transmissions, this updated unit replaces our original design with a more robust and streamlined solution. Our original unit relied on a number of stacked tolerances from multiple vendors, which often resulted in shorter than expected life. At the heart of the new setup is a proven, self-contained bearing sourced from a Suzuki Vitara. It's a single pre-assembled unit with OEM reliability. While this bearing has made appearances in other Miata builds, our version stands out with a precision-machined mounting plate that replaces the factory guide tube for a clean installation and perfect alignment. Key features include: Simplified design thanks to the OEM-style bearing Compatible with the factory 5/8" master cylinder. No need to upgrade to a 3/4" Wilwood u
