The 3RACING Aluminum Center Pulley Gear T27, designated 3RAC-3PY/27, is produced to support competitive drivetrains that rely on consistent 27-tooth centre engagement. It is intended for users seeking a robust, low-mass pulley that maintains accurate tooth form under load.
Using aluminium reduces susceptibility to deformation while keeping rotating inertia low. The 3RACING 3RAC-3PY/27 provides improved surface durability versus polymer counterparts, which helps maintain mesh precision during extended runs.
Confirm shaft diameter and mounting interface prior to installation. Set mesh with minute adjustments and secure fasteners to specified torque; re-inspect after initial break-in laps to verify retention and alignment.
For racers, swapping to the 3RACING 3RAC-3PY/27 can reduce drivetrain wear and contribute to repeatable lap times by preserving consistent engagement. Consider complementary upgrades such as high-quality bearings and properly sized drive components.
