GM 10-Bolt Steel Full Spool, 30 Spline

Spools are an alternative to a locker as traction and performance enhancement. Spools are a favorite of off road competitors, dirt track racers and drag racers. A differential with a spool set up delivers equal power and traction to both left and right side rear wheels. Spool solutions are less expensive than lockers and weigh less. We offer a full line of mini and full spools in the most popular applications for such differential modification.
