RTS CSC-1255 Concentric Slave Cylinder (Clutch Release Bearing) for Ford Focus ST225/RS Mk2/Mondeo Mk4/Kuga/S-Max/Galaxy & Volvo C30/C70/S40/S80/V50/V60/V70 - Hydraulic Direct-Fit

RTS Hydraulic Throwout Bearing / Internal Clutch Slave – Part No. CSC-1255

Upgrade your clutch hydraulics with this OE-style, drop-in hydraulic release bearing designed for popular Ford and Volvo manual transmissions. The RTS CSC-1255 is a direct replacement internal slave that delivers crisp engagement, consistent pedal feel, and reliable operation whether your car is a daily driver or a fast-road build. Perfect when refreshing a clutch assembly or pairing with an uprated friction kit.

We have installed this unit on our own development cars and customer vehicles at MJ Modifications, and feedback has been consistently positive for drivability, smooth take-up, and long-term reliability. If you are undertaking a clutch change, replacing the internal slave at the same time is smart preventative maintenance that helps avoid leaks, judder, soft pedal, or premature wear.
