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.

 

For even lighter weight, there are aluminum-alloy versions available for some applications.
