Housing End Type

 

Use the images and dimensions below to identify the housing end type. Measure the Brake Space (BS) to verify axle fitment as Ford used several different combinations of housing end and brake space dimensions during production runs. If your housing end and brake space dimensions do not match the sizes shown, please call as we have many axle options.

 


Late Big Bearing (Torino)

 

 

 

 

Early Big Bearing

 

 

 


Small Bearing

 

 

 

 

Axle Brake Space

 

Brake Space (BS) is the distance from the face of the housing end to the face of the axle; this is a critical dimension for proper brake fitment. If your housing end type and brake space dimensions do not match the options below, please contact sales to speak with one of our experts.

 

Standard Brake Space Dimensions

  • Late Big Bearing   = 2.5-inch brake space
  • Early Big Bearing  = 2.365-inch brake space
  • Small Bearing       = 2.52-inch brake space

 

 

 

Axle Face, Register Diameter and Bolt Pattern

 

Axle face and register diameter are essential dimensions for proper brake fitment. A slightly smaller axle face diameter is acceptable, as this does not create clearance issues for brake fitment. The register diameter is a critical dimension as it serves to locate both the drum or disc brake rotor. Use a dial or digital caliper to measure the register diameter to 1/1000th of an inch accuracy. If your axle face or register diameters do not match the size options above, please contact sales to speak with one of our experts.
