Cast Iron 9 Inch Ford Daytona Pinion Support
                        

This pinion support is cast from 30,000 psi gray iron and is far superior to the original Ford unit. Daytona supports have a larger rear (inner) bearing and race along with improved oil flow to the bearings. This allows for higher torque, horsepower, and longer bearing life. Pinion support weighs 6 lbs.

Bearings and races sold seperately.

  • M88048 Front pinion bearing
  • M88010 Front pinion race
  • HM89443 Rear Daytona pinion bearing

  • 10-7/16" x 20 right hand threaded bolts
