PRW Harmonic Balancer Hubs

PRW harmonic balancer hubs are the precision-machined inner core parts of an engine's harmonic damper that mount directly onto the crankshaft. Order the model recommended for your vehicle.

* What they do:
-- Connects to crank: The hub slides and presses onto the end of the engine's crankshaft
-- Holds the damper: It supports the outer weight ring or fluid-filled chamber that absorbs engine vibrations
-- Reduces stress: It keeps the rotating assembly stable and protects the crankshaft from cracking under high speeds
* Key features of PRW hubs:
-- Strong materials: PRW builds hubs from tough nodular iron or forged billet steel
-- No slipping: Many PRW designs use a splined connection between the inner hub and outer ring to stop movement
-- Race-ready: Many models meet SFI safety rules for high performance and racing use
-- Accurate fit: They feature precise center holes for a secure press-fit onto the crank snout
