GForce Axles have become synonymous with record breaking consistent performance and have proven to be the go-to solution for anyone looking to get the most from their factory driveline setup. Not all vehicles have an optimal design or the most ideal spline counts to boost strength, but you can be confident that GForce axles are engineered to be the absolute strongest possible to work within the space provided by the OEM manufacturer. GForce offers two different axles for most applications. If you would like to know which is best for your application, you can read more here: Renegade vs. Outlaw Axles

Specific notes for 2015+ S550 / S650 Mustang:

• All Standard S550 axles are designed to work with the factory 34 spline differential and 32 spline wheel hubs on the GT and GT350 models
• We are proud of the fact that our S550 axles have set a standard and received an endorsement from and automotive icon as big as Ford Performance in the FRPP axles. This opportunity has paved a path for testing and innovation that have allowed us to put axles behind some of the fastest S550’s in the world.
• Our standard Outlaw and Renegade have found their home on numerous 750-900hp cars, with many pushing well beyond. Drag racers who are looking to run mid to low 8’s or really get after the short times might consider upgrading to the “exotic” outer stubs, as the standard stub starts to become a weak link. The exotic stubs were originally reserved for the complete 9” conversion kits, but we have had more and more customers pushing the limits of the factory differential in excess of 1400hp. A failure on a standard outer stub would cost considerably more than the cost to upgrade to the exotic stubs when purchasing new, so it is a good idea to consider if you know the car is going to be seeing a notable amount of abuse. Important to note that any axle can fail at a lower power level due to wheel hop or misuse. The listed numbers should not be an expectation, but an idea for capability.
• We do offer 9” conversions as well for the customers who do not want to be concerned with any reliability issue stemming from the factory differential.

Fitment
GForce axle shafts were manufactured based on OEM suspension. Aftermarket shocks, control arms, etc. may present clearance issues. If CV boots have clearance issues, low profile boots can be purchased at an upgraded cost. The low profile boots reduce the amount of available axle angle in comparison to the standard boots, so they are not ideal for lowered or high axle angle vehicles. This includes 2010-15 Camaro and all years of Mopar platforms. If you have questions or would like to add low profile boots to your axles, please contact us for more information.

Damage Prevention
NO DRIVELINE COMPONENT IS BOMBPROOF! GForce does not put a power rating on any driveline components as there are entirely too many variables that can affect a driveline component outside of power. We take great pride in trying to build the strongest driveline components to fit within certain applications, but it is important to know that You, the end customer, are responsible for seeing to proper installation and You, as the driver, are responsible for the lifespan of your axles or other driveline components.

Service
All driveline components will fatigue or wear over time depending on how the vehicle is driven and what level of performance is demanded from them. CV joints are a wear item and will see wear over time, but with our current design, axles can be sent in for service. So boots, fasteners, and CV assemblies can be serviced without scrapping the complete axle assembly. It is up to each customer to establish their own maintenance intervals based upon the manner in which their car is driven. Individual inner or outer splined stubs and axle bars can be replaced as well if they twist or are damaged due to wheel hop or simply from power levels exceeding capability of the material. Customers can reach out to GForce directly for current repair costs or component replacement as well as return authorizations for service – [email protected]
