Built Tough for Performance

Spicer Performance Spools meet the latest performance demands by offering exceptional traction, giving you a distinct advantage whether you're driving off-road or on the track. These spools deliver with options that standard spools cannot offer and are not recommended for everyday street driving. Spicer spools eliminate situations of high-torque, high-impact failure by removing the need for a differential case. Spicer spools are designed to allow you to push the boundaries and are constructed of forged chromoly 4130 steel that is heat treated for optimal hardness. These spools are available for a variety of applications including lightweight versions that provide a lighter rotating mass.
