3RACING 3RB-R166-ZZ/2 Racing Grade Double Metal Shield Bearings  [3RB-R166-ZZ/2]

Race-Oriented Bearing Upgrade from 3RACING

For drivers tuning setups, the 3RACING 3RB-R166-ZZ/2 bearings offer predictable, low-drag rotation that complements suspension and drivetrain adjustments. Their double metal shield design helps retain lubricant under hard running.

Consistent Shield Protection and Smooth Spin

The twin metal shields reduce ingress of abrasion particles while preserving internal lubrication, which supports repeatable lap times and stable feedback through the steering and throttle. The bearing dimensions of 3/16 x 3/8 x 1/8 inches fit many tuning positions where roll resistance matters.

Suitable for Setup Work and Component Matching

Use these bearings when refining a racing rig or replacing worn parts to maintain consistent rotational characteristics across wheels and differentials, aiding predictable handling and simpler tuning sessions.
