Currie Rear Axle Installation Instructions

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

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.

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.

This is a standard run of the mill 31 spline 9" Ford rear end. You should look into some drag racing rear ends which are designed to handle that sort of power. Sorry we do not offer anything that will be up to the task.

Theis bare axle housing kit could be used but will require welding on the spring pads and other parts. We do offer a complete 9” housing with brackets and axles installed for the 67-70 Mustang in the correct width under number 91046770. To complete the installation with the third member number 91048345 with a 350 ratio and comes with the Currie posi unit ready for installation. Add a gasket number 9192300 and a gallon of lube of choice and you are ready to install. We also offer complete drum brake kits or bolt on disc brakes if so inclined.

Part number 91045100 is a 9” rear axle option for our earlier hot rod chassis and offers a 56” hub face to hub face dimension and the installer would need to add the necessary mounts for the leaf springs, etc. Speedway offers a direct bolt in for the 70-81 Camaro under part number 91007081. It includes the Currie axles and if you add the third member under number 91048345 in the desired ratio and the brake package you prefer whether disc or drum you would have a bolt in rear end the correct width with the strength of a 9” Ford. Add the gear lube and gasket and you would be set.

Hey is the pinion centered or is the housing centered putting the pinion off center and if so how much off?

This is a centered housing rear end with a pinion offset of approximately 2 3/8”. It uses a short and long axle to compensate for the offset.
September 19, 2012
KENT
This particular kit is housing centered. Housing centered on the 9" means that the pinion is offset to the passenger side .94 inches from center. When housing centered, if you measure from the pinion to each housing end, there will be a 2 x .94" = 1.88" difference in measured lengths. (1 side was shortened .94" and the other side was lengthened .94")

If you have a particular wheel and tire combination that you want to use then the best bet to get them to fit correctly into the tight wheel well of your Nova will be to remove the stock rear end then mock up the tires and wheels that you will use and measure from wheel to wheel to get the perfect width of rear end.

Ford 9 Inch Posi Traction Third Member Assembly
(Part #91048345)
                        

If you’re looking for a complete third member for your Ford 9-inch rear end housing, but want the added performance of a limited slip differential, Speedway Motors now offers you a 9" Ford street 3rd member for your street rod. We start with reclaimed, genuine Ford 9-inch carrier housings and then clean and inspect them prior to installing all-new bearings, seals, a 1310-series yoke, and your choice of ring-and-pinion gears. The 1310-series yoke is the correct size for many Ford applications with cups 1-1/16 inch in outside diameter and a span of 3-7/32 inch across.

These Ford 9 inch third member assemblies feature a Richmond Powertrax Grip Pro differential available in 28 or 31 spline axle shaft configurations. This clutch-type differential is perfect for light-to-medium weight street vehicles where one wants posi-action and long clutch life, without the adverse handling effects or noise of a full locker. When coasting around turns, the clutches are disengaged to extend clutch life. When accelerating in a straight line on dry pavement, the clutches engage, sending equal power to both wheels for maximum traction. This makes them ideal for street use, with the occasional trip to the drag strip as well.

All third members are assembled by our team of professionals and are delivered to you in a handy plastic carrying case, for an overall value that can’t be beat

Available in your choice of 3.50, 3.70, 3.89, 4.11 or 4.56 gear ratio.

Gear lube recommendations :

  • 910-44090 - for street and every day driving under normal conditions
  • 910-44140 -  for extreme duty, towing, or very hot climates

New 9 Inch Ford Iron Carrier Housing w/3.062 Inch Caps
(Part #91048390)
                        

If you have built anything that has serious horsepower you know the weak link can be the stock Ford 9" carrier. The pinion area tends to be weak and if you throw enough power at it, it will break. That won't happen with this brand new housing. 

This new cast iron housing is built to take street/strip abuse without the fear of breaking. Case has forged caps and extra beef where it's needed. Most stock differentials use the 3.062" o.d. bearings # TLM603049 w/ 1.781" i/d. You should also add a new heavy duty cast iron pinion support while you're at it. 

  • Forged Steel Caps
  • 1/2" Allen head grade 8 bolts
  • Heavy Duty Housing - 36 lbs.
  • Good for 1100 plus horsepower
