Strange Lightweight Pro Race spools give you the traction that you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. They're CNC-machined from forged chromoly steel to provide a more rigid ring gear mounting. This eliminates the gear failure caused by case deflection or differential side-gear failure. For even lighter weight, there are aluminum-alloy versions available for some applications.
