Now Available: The Redesigned Miata Hydraulic Release Bearing

We’re excited to introduce the completely redesigned KPower hydraulic release bearing for the NA/NB Miata. This updated version improves long-term reliability, simplifies installation, and is compatible with the stock hydraulics. Just like before, it is available in 5 and 6-speed configurations.

The original design relied on tight tolerances across multiple vendors. While many units worked well, variations in anodizing and piston fit sometimes led to inconsistent tolerances that reduced the life of the part. Rather than continue refining a complex setup, we decided to rethink the part from the ground up.

The redesigned unit uses a proven, self-contained OEM-style hydraulic bearing sourced from a Suzuki Vitara. We’re aware this unit has seen use in other Miata builds and aftermarket applications, but we’ve focused on making the cleanest and most reliable installation yet. Our precision-machined mounting plate replaces the factory Miata guide tube and ensures proper alignment and fit without the guesswork.

This new design also compatible with the factory 5/8" Miata master cylinder, eliminating the need to upgrade to a 3/4" Wilwood unit.

If you purchased an original KPower release bearing that's still working well but you would like to upgrade, please contact us for a special discount. And if you have an original unit that has failed prematurely, we'd also like to help. Please contact us at info@kpower.industries with your original order number.
