Toga HP Bearings are meeting those demands and extending the life of today's performance Import motors. Most Toga HP Series Mains sets are full grooved to maximize oil flow to the rod bearing. Both rods & mains have a high crush for max retention and reduced overlay thickness to prevent fatigue. Rod bearings use hardened steel backs for added strength. Toga HP bearings should be used wherever high RPM's (above 6000), nitrous, superchargers, turbochargers or any application where above normal HP & RPM's are made. All motors benefit from these HP bearings. These bearings will give longer life to any engine by increasing oil to the pins & eliminating oil starvation. All bearings are Tri-metal cast copper lead with copper lead lining to withstand engine loads, along with electroplating babbitted overlay providing optimum service. All bearings are stamped with a red HP. Stock bearings are made for stock applications, but today's Imports are stretching the abilities of stock components and demanding much more.
