Bolt-in Hydraulic Release Bearing

PTT's Tri-MAX Hydraulic Release Bearing (HRB) is the most reliable, lightest, and strongest bolt-in HRB on the racecar market. Tri-MAX is designed to work with all small diameter multi-disc racing clutches and will fit Muncie, Jerico, Roltek, T-10, T-101, Saginaw & other transmissions. Tri-MAX has a full 3/4" of release travel, (the longest travel in its class) and has superbly engineered hydraulics 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! Tri-MAX works best with 5/8" or 3/4" master cylinders.

Tri-MAX is CNC manufactured to aircraft industry tolerances from high strength aluminum. All moving parts are premium hardcoat anodized for long, trouble-free life. Tri-MAX is designed for, and has been pressure tested to over 2500 p.s.i. with no failures. All Tri-MAX bearings are pressure tested to twice normal operating pressure before leaving the factory. You can bolt a Tri-MAX in with confidence knowing that it will work as advertised right out of the box. The velvety smooth clutch actuation you get from a Tri-MAX has to be felt to be believed. Tri-MAX is the reason you want to run a hydraulic release bearing.
