9" Ford & 12 Bolt Chevy Aluminum Spools

We custom make these 7075-T6 Billet Spools in house at Neil & Parks with unique features. They utilize Dana 35 Splines - compatible with all makes of axles except for Mark Williams.

The splines are broached to the very end of the spool allowing shorter, stronger and lighter axles. This also reduces the "shear off" of the bearing journals.

Available to fit 9" Ford 2" bearing journal (3.250 bore case) and for 12 Bolt Chevy Car 4 series. Our 12 bolt version is stronger than the competitors to reduce bending in severe duty applications.
