Steel Crank Hubs
Leading professional drag racers have used small diameter, lightweight steel crank hubs in place of heavy stock dampers for years. They know that just like a lightweight flywheel, a lightweight crank hub allows the engine to rev quicker for faster engine response.
B&B Steel Crank Hubs are the ultimate in strength, precision and lightweight. They are fully machined from solid chrome-moly steel bar stock. Each one is completely finish-ground and marked in precise 1-degree increments. B&B Crank Hubs are 4 inches in diameter.
