Clutch Masters HRB Hydraulic Release Bearing for Evo 4-9

These Clutch Masters hydraulic release bearings (HRB) are used with the Evo 4-9 725 and 850 series twin and triple disc clutch kits for a push-type conversion. The mounting points are different for 5-speed and 6-speed transmissions. As of now, CM only offers the full clutch kits with the 5-speed HRB, but you could purchase the 6-speed bearing and install the push-type HRB conversion in your MR trans.
