Strange Lightweight Pro Race Spools

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.
