Custom Rear Ends

To build a custom rear end for your vehicle, we require the information outlined below:

1. Overall Width (Dimension A below): The overall width can best be determined by putting the tires under the car (make sure to allow a minimum of one-inch clearance for the fender and the frame rails) and measure the distance between the wheel mounting surface on each wheel.

2. Pinion Offset: (Dimension PO below): The pinion location in most cases will be centered; in some cases, the housing is off-center to accommodate drive shaft or suspension bracket clearance

3. Wheel Lug Bolt Pattern: The lug bolt pattern is the number of studs and the diameter of the circle on which they are placed. See the image above for details on how to measure the circle diameter.

4. Vehicle year make and model:

Housing End Types

Below are shown the three housing ends that Currie Enterprises uses when manufacturing a custom & rear end. For new rear ends the Late Model Large Bearing end is the standard. For replacement rear ends, where the original brakes or axles will be reused it is important to specify the correct housing end type. Refer to the images and dimensions below to identify your vehicle's housing end type.

If you don't know exactly how to determine the dimensions listed above, then it would be a good idea to have the following information before calling a Currie Enterprises Sales Representative:

1. Tire Diameter
2. Horsepower
3. RPM Range of CAM
4. Type of Transmission
5. Intended Use of the Vehicle
