Fabricated Rear Knuckles for Ford S550 Hubs, Super 8.8 Independant
A new product we have been working on this year and it is finally finished. These knuckles use the Ford s550 unit bearings. Along with the same rotors and calipers as our other knuckles to keep everything as simple as possible. The caliper bracket on these knuckle bolt on to allow caliper upgrades in the future when we put out more updates. With the super 8.8 differential found in the 2015 and up mustang platform paired with our knuckles is a strong combination not to let you down when you do your Ls swap. The super 8.8 rear subframe will be available soon.

With the introduction of the S550 platform for model year ‘15, Ford made the independent rear suspension (IRS) standard equipment across all Mustang models. This was an unprecedented decision for the original pony car (with the exception of the 99-04 Cobra) and brought the refinement of European sports car handling to the iconic American Mustang platform. With this new suspension design brings a new differential, which Ford calls the Super 8.8. The ring gear size is the same as its predecessor, hence the 8.8, but that is where the similarities end. Let’s take a look at the S550 differential options.
Ford introduced the S550 platform in the USA with three powertrain options: the 3.7-liter V6; 2.3 liter-I4 Ecoboost; and the powerful 5-liter V-8. Every model comes equipped standard with a Trac-Lok limited slip differential. Each powertrain option has different gear ratio options available depending on your preference for auto or manual.
