Description

Want to tear up the pavement and not your differential housing? Steeda has the part for you! Steeda's HARDCORE S550 Mustang Differential Brackets were developed after multiple aluminum differential housings had front ear failures at the track. This simple bolt-in part locks the differential in place and redistributes the loads so that the front ears are under less stress. This enables you to run the aluminum differential housing, which shaves 20+ lbs off of the rear of your S550! The Steeda HARDCORE S550 Mustang Differential Brackets are a must for anyone running today's compounds drag radials and slicks. NVH will be added, but this is a simple install that can be done before a track day and removed when hitting the streets in your daily.

Decrease wheel hop and rear differential movement on your S550 Mustang by adding these braces, differential pinion rise and lateral movement are significantly reduced. Less drivetrain movement means more power to ground. More power to the ground means more enjoyment out of your Mustang.

Steeda's design has also eliminated the single shear design which exists between the rear differential mounting ear and the rear subframe bushing, replacing it with a triple shear design. This reduces the average stress on the bolt, allowing for 3 times the load capacity! But Steeda didn't stop there. We have also added upgraded hardware for an added factor of safety, ensuring you confidence when launching your Mustang.

Used in conjunction with our all new 555-4051 - Steeda S550 Mustang THRU Threaded Differential Bolt Upgrade Kit, you'll have no worries riding your Mustang to fast times.

Product Benefits:
  • Decrease wheel hop
  • Reduced pinion rise and differential bushing deflection
  • Less movement = more power to the ground
  • Eliminates single shear design
  • Upgraded hardware

Better than expected
The install was a little different than the instructions because I couldn't use the supplied allen heads for the brackets on the front of the housing. My Gforce axles are larger diameter than the stock ones, so I had to reuse the stock bolt. Ended up leaving the top bracket bolts out and put the bolt thru both brackets and then slid it down into place. Luckily I was able to use my friends lift, so it made it easier. After the install, the ass end clunking is a little quieter, but the howling from the rear gears is more prominent. Regardless, the cars reaction to the throttle has definitely improved.

Works as Advertised
I purchased this product for my 2018 6 speed Mustang, and it works as advertised. It cured 90-95% of the wheel hop on street tires (that last 5-10% is due to the street tires). On the track I had zero wheel hop on a MT Et Street R Bias Ply. The instal instructions were a little vague but the install wasn't to bad. I found that if you drop the subframe the install would be a breeze, with the subframe up it is a little tight. Now since this is a solid brace you will get NVH. I did not mind that as I had longtubes and didn't care about NVH. All in all, this part works and I will definitely buy it again. Thanks Steeda !
