PTT Hydro-MAX Hydraulic Release Bearing

PTT'S Hydro-MAX Hydraulic Release Bearing (HRB) is the lightest, trickest, strongest HRB on the racecar market. Weighing under 1-1/4 pounds sopping wet, Hydro-MAX is 30% to 60% lighter than all other return spring equipped HRB's currently available! At just over 2-1/4" tall, it is also the shortest. It has a full 1/2" of release travel, (the longest travel in its class), and a built-in return spring to ensure positive, 100% clutch engagement. PTT's custom-designed, low drag, 1.6" radius face bearing is standard equipment. The smaller diameter contact reduces clutch pedal effort, while also lowering the thrust on the back of the crank!

Hydro-MAX is CNC manufactured to rigid PTT quality standards from high strength aluminum and then hard coat anodized for long life. Every component that goes into the construction of Hydro-MAX oozes quality, from the custom designed AN & bleeder fittings, to the highest quality rubber compounds in the o-rings. Every Hydro-MAX is pressure tested at the factory to over twice it's normal operating pressure. Hydro-MAX is designed and built to take the night after night, weekend after weekend abuse that professional auto racing dishes out.
