Pinion Flanges

A pinion flange—also called a companion flange or yoke—connects the driveshaft to the differential pinion, transferring torque while allowing for slight driveline movement. Whether you're replacing a worn factory flange, converting to a different driveshaft style, or setting up a custom axle, the right flange ensures a solid, vibration-free connection.

Our selection includes flanges with common domestic and import bolt patterns, flat and recessed pilot designs, and spline counts to match popular differentials. Finishes vary from bare machined steel to corrosion-resistant coatings for daily-driven or high-horsepower applications.

When narrowing your options, confirm:

  • Flange type (flat vs. recessed pilot)
  • Bolt circle diameter and mounting hole size
  • Spline count and pinion shaft diameter
  • Overall height and pilot diameter

Pair with the matching pinion nut, seal, and crush sleeve for a complete installation. Browse below to find a pinion flange that matches your drivetrain setup.
