Spools are designed to positively lock both axles to assure both tires rotate at the same speed greatly increasing traction and directional stability. Available for all popular applications. NOT RECOMMENDED FOR STREET USE.
Strange Lightweight Pro Race spools give you the traction you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. They're CNC-machined from forged chromemoly steel to provide a more rigid ring gear mounting. This eliminates gear failure caused by case deflection or differential side-gear failure. For even lighter weight, there are aluminum-alloy versions for some applications.
