Do not measure your existing axle length. Currie builds custom axles using the Driver's side "X" and Passenger's side "Y" dimensions shown below
All dimensions should be accurate to 1/16 of an inch to assure a proper fit
For the "X" dimension (Driver's side axle), hook the tape measure on the stud (as shown) and measure to the outside edge of the housing end flange
For the "Y" dimension (Passenger's side axle), hook the tape measure on the stud (as shown) and measure to the outside edge of the housing end flange
Currie Drage Axles are compatible with Ford early large bearing housing ends only
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 size below, please contact sales to speak with one of our experts
Early Big Bearing = 2.365 in. brake space
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.
