What's in the Box

Info

These axles have 4" of spline which will allow you to cut a maximum of 3" of the spline off to obtain the correct length. This is perfect for small shops and will allow you to build your own custom width rear end easily. Axle length is measured from the flange to the end of the splines. All CTF axles come with a full installation package which includes one set of five 1/2"-20 Ford style wheel studs, one set of five 7/16"-20 Chevy style wheel studs, one set-20 tapered roller bearing with race, seal, & collar, and one heavy duty late model large bearing style retainer plate.

  • 9 Inch Ford
  • 31 Spline
  • 26 Inch Long
  • Drilled for both 5 on 4-1/2" and 5 on 4-3/4" wheel bolt patterns
  • Includes both 7/16"-20 and 1/2"-20 wheel studs
  • Compatible with "Big Ford - New Style" housing and brakes with 2-1/2" offset
  • Includes a set-20 bearing and retainer you will have to press on
  • Axles sold each, not as a pair

How to Measure Your Housing Tech Tip (Link)

Need a certain length not found on our site?  Check out Currie's 9+ Rearend Calculator to have specially sized axles or rearend housings made for your specific application.  Custom orders will be built and processed directly through Currie Enterprizes and shipped to your door. For ease of ordering, please refer to Currie's Dimension Diagram

 

Notes

Installation Notes:

When installing new axles in rearends with posi traction differentials, be sure to install the driver's side axle first to keep the splines properly aligned.  Failure to do so may move the two splined gears out of alignment, and it may be difficult to install the driver's side axle properly if the passenger side axle is already installed.

If installation of passenger side axle is done first it may require two people when installing the driver's side axle, with both parties rotating reach axle until splines are in line and the driver's side axle fully sides into the housing.

When cutting axles to desired lengths Currie recommends: 

  • Normal steel cutting machinery (cold saw, band saw, chop saw, etc.) 
  • Using a sleeve around the axle such as a small piece of PVC tubing - this allows:
    • The axle to be spun in place while being cut
    • A perimeter cut around the outer diameter assisting in keeping the cut square
    • Avoiding the build-up of too much heat by doing a straight cut (like a knife though a stick of butter) 

To ensure you get the most out of your new 9 Inch components, Currie recommends that you perform a proper break-in process:

  • Use a name brand mineral-based gear oil, preferably 85w140 (Extremely high quality synthetic oils may be used once break-in process has been successfully performed)
  • Place vehicle on jack stands and let the rearend spin while the vehicle idles - run transmission in both forward and reverse periodically throughout the process
  • Continue to run the rearend until the pinion gets hot (place hand on bottom of the differential housing to verify this)
  • Proper break-in allows:
    • The ability to install new axles and hit the track the same day without worry
    • Extended life for rearend components
    • Keeps the quality and life of your gear oil

Note: If you find that your rearend is running somewhat "tight" be sure to add Currie's 9+ Friction Modifier to "loosen up".  If a more aggressive performance is desired, Friction Modifier is not needed.

great way to a custom axle

March 04, 2016
this was very easy to use, it is well made and comes with everything you need. watch out for the ford ends, I ordered according to the shape of my housing end. do not do this, measure your bolt spacing before you order. they only make them in 2 lengths, they need to offer a couple more sizes. I would definitely use these again.
Pros:
  • Everything You Need
  • Easy To Install
  • Easy To Cut
  • Great Package
Cons:
  • Not Enough Sizes
Yes, I recommend this product.

For these axles do I measure from inside the spider gear of the differential to the end of the rear end housing or to the back side of the axle flange? A diagram would be helpful. thanks

Axle length is overall length from the end of the splines to the face of the axle. So if you measure to the depth of the splines on the spider gear to the face of the housing flange and add 2.5 for the axle offset that will be the length needed.

Thanks for you question on our Currie Cut to fit Axles. The axles have 4” of spline. You would be able to trim up to 3” off the end so you are correct if you would order a 26” axle it could be shortened to 23”. Hope this helps you out. If you have any further questions feel free to ask them. We appreciate you using Speedway Motors.
