Q & A

What's in the Box

Now you can have the strength and serviceability that Ford drivers have enjoyed for years underneath your GM vehicle. Currie Crate Rearends are built using the stock overall width, pinion offest, and mounting points of your original rear axle housing, making it a 100% bolt-in upgrade.  Designed as a bolt-in kit for 1955-57 Chevy Car applications.

  • All new 9-Plus heavy duty housing
  • Replacement fit for 1955-57 Chevy chassis
  • Heavy duty 2” wide leaf spring pads installed in the stock location
  • 31 spline performance axle shafts
  • 60" width
  • Torino-style late model large bearing housing ends
  • Third member studs installed
  • Axles drilled for stock 5 on 4-3/4" wheel bolt pattern
  • 7/16"-20 wheel studs pressed into axles
  • 1/4” thick heavy duty bearing retainer plates
  • Tapered Timken style wheel bearings pressed onto axle

Note: Works with Speedway rear disc brake kits, 11" Ford Explorer disc brakes, and Wilwood disc brakes. Third member sold separately.

How to Measure Your Housing Tech Tip (Link)

To learn more about Currie's 9+ rearends, check out these Frequently Asked Questions on 9-Plus Housing (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 60" wide from axle flange to axle flange and has a 2 1/2" axle offset so the housing only will measure 55" wide from bearing flange to bearing flange.

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
