Introducing: The FerraroSpeed 8.8 Axle Brace!

The FerraroSpeed 8.8 Axle Brace: It's finally here and US patent pending!

The FerraroSpeed 8.8 Axle Brace fits most modern 8.8 axle designs, but is specifically marketed and designed as an SN95, New Edge and S197 mustang 8.8 axle brace.

There are two part numbers:

FERBR9904-BPC  (94-2004 Mustang)

FERBR197-BPC (2005-2014 Mustang)

Constructed of powder coated aluminum, the 8.8 axle brace unit weighs less than 5 lbs and provides advantages over other designs: It balances the load over the entire case, bolting under the stock differential cover. The clamps secure with grade 8 hardware, for a strong, lightweight and easy to install brace. This is the perfect solution if you want more strength, but don't want to upgrade to a 9" rear.

Rear lower control arm relocation brackets will not interfere with this brace! The 8.8 brace installs easily with a 2 post lift or on jack stands (access is far easier when the rear suspension is unsprung).

How to install the FerraroSpeed 8.8 Axle Brace:

Recently, Justin Jordan of Jordan Performance and Racing installed one on his customers 2014 Mustang GT. Below are the installation photos, as well as installation instructions.

Before we start, we'd like to extend a huge thanks to Jordan Performance & Racing, owned and operated by Justin Jordan. They are a performance and tuner shop located in Ruskin (Tampa), Florida.

Justin's accolades in drag racing make him the perfect candidate to handle your upgrades, ranging from simple, street performance modifications to full blown race car development.

His 7 second 2013 Mustang GT, aka "nighTTmare" has consistently performed in the low 7's (1/4 mile) and he has attracted sponsorship from national brands, including MBRP Exhaust and Gulf Racing Fuels.

Justin's car wasn't in the shop with us, but his customers 2014 Mustang GT (as well as a Z06 and another TT mustang), provided all of the eye candy we needed.

We started with a mostly stock 2014 Mustang GT. This car was in for a blower, Injector Dynamics injectors, oil pump gears, a custom tune, and an HP Tuners nGauge.

With more modifications planned, it only makes sense to strengthen the 8.8 rear end with the 8.8 axle brace.

Let's jump into it, shall we?

First, here is the list of tools and supplies needed:

  • 1/4" T-handle or hex bit.
  • 10MM hex bit (hex socket)
  • Gear oil pump. Like THIS one.
  • 2+ quarts 75w140 synthetic gear oil with limited slip additive.
  • Permatex black gasket maker (OEM requirement on late model 8.8)
  • Oil change pan
  • Brake cleaner
  • Razor blade or gasket remover tool
  • Blue Loctite

Lift the car on jack stands or on a 2 post lift. (Ramps or a 4 post lift will make access unnecessarily difficult).

Yes, the first photo shows the car on race ramps. Ignore it =o)  Allowing the suspension to remain unsprung gives better access to the rear cover. 

Important: With your current setup, make sure there is more than 1/2" clearance between differential cover the panhard bar. This should not be an issue with the stock cover, even with an aftermarket bar, but some aftermarket covers may be a tight fit.

Remember: Race car parts! Your mileage may vary. Measure first! If it's too tight, relocate the panhard bar or use the stock differential cover.

Loosen the 10 differential bolts and drain the gear oil. Once drained, remove the stock cover. Your best bet is to pull the bottom 3 or bottom 5 bolts and pry open with a screwdriver. Use brake cleaner and a gasket remover blade to clean the cover. 

Take the time to make sure it's clean!

Once the mating surfaces are cleaned with brake cleaner and wiped down (do this on the brace, too) per OEM specs, use black permatex/gasket maker and form a bead on both sides of the brace. Mock up the cover first, to make sure you cover the correct areas.

Apply gasket maker to the cover. Let stand for 3-5 minutes. Carefully raise the brace and line up the holes on the rear end, then slide the cover in on top, keeping the holes aligned.

Hold the brace up and secure it loosely with one of the top bolts. Slide the cover in and make sure you have clearance to go between the gear and the panhard bar. If not, pop one of the brackets and temporarily move the panhard bar down.

Insert two bolts on opposite ends, then install and torque all bolts to OEM specs. Use loctite on the bolts and tighten with a 1/4" t-handle or hex socket.

Once centered, tighten all differential cover bolts torqued to spec. It should look like this.

Next, bolt on the clamps using the provided (larger) hex cap screws. Torque them to approximately 50 ft lbs.

Refill the differential with gear oil. Use a hand pump if necessary. Yes, this seems like an obvious step, but if you forget it, you can't blame us now, can you?

Inspect for leaks, bolt the panhard back on (if removed), lower the car and let it sit for a couple of hours. Take a short drive. Check for leaks again, re-torque if necessary.

Race with more confidence! As with all race parts, inspect after a few passes and re-torque if necessary.

Total Labor time: 1 hour (1.5 hours with repeated attempts to get decent photos).

The FerraroSpeed 8.8 Brace can be bought HERE and we are now accepting orders. Orders will begin shipping on Thursday, January 26th! Dealer pricing available!
