Description
A full spool differential eliminates wheel spin by locking both rear wheels together, delivering maximum traction off the line—essential for dedicated drag racing, street racing, and high-performance driving where consistency matters. The PEM 9in Gear Full Spool with a 6.33 ratio is engineered for Ford 9-inch housings and offers aggressive gearing suited to naturally aspirated and forced-induction builds seeking quick acceleration and track dominance. If you’re running a serious racing program and need predictable, no-slip power delivery, this assembled center section is ready to bolt in and perform.
