2018-2021 JEEP TRACKHAWK BILLET DIFFERENTIAL, GFORCE AXLE, and ECD DRIVESHAFT KIT

This 9” differential is designed to bolt into the Trackhawk rear cradle. No modifications are necessary for the install of this unit! This diff was custom designed and fit to maintain correct cv shaft and drive shaft angles, avoiding any undo stress or vibration in your car.


These diffs come ready to install with 3.70 gear ratio, 35 spline pinions. A 35 spline 108mm CV yoke maintains the factory location, making and factory length driveshaft compatible during install. Eaton Truetracs are the standard traction device in these diffs and are paired with 35 spline, 108mm chromoly stub shafts.  Stub shafts have been designed so the Gforce cv shafts can be reused with this differential.  

Please contact us for Axel options or if a pro gear or non standard traction device is desired.

 

2018+ Jeep Grand Cherokee Trackhawk 6.2L (WK2) Renegade Axles

Due to high demand, new axle orders are expected to have up to a 4-6 week lead time.

 

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.

Specific notes for 6.2L Jeep Grand Cherokee Trackhawk:

  • Trackhawk uses a 32 spline inner stub and 35 spline outer stub
  • MUST USE aftermarket differential bushings or differential brace to help prevent damage to axles from excess rear end movement. Damage that occurs due to the stub not being seated fully will NOT be covered under warranty.
  • It is important to understand that this is an exceptionally heavy vehicle, making a lot of torque with a steep 1st gear… These axles have served our customers very well, but it is important to realize that we are asking a lot of a 32 spline inner stub and 31 spline axle bar. These are the strongest components that we can make to work within the OEM specifications, but that does not mean they are bombproof. These vehicles are also very prone to wheel hop, which increases the likelihood of axle or driveline damage. We are planning options for a 9″ conversion down the road, but it will be more involved than our standard kits and will take more time to develop. We have numerous customers at 1100hp who haven’t hurt anything; We’ve had customers with numerous runs at 1400 who eventually hurt parts and customers as low as 750 who have hurt parts. Our average customer hovers around 900-950. At this level, it doesn’t take much of a mistake to hurt something if you strike the tires wrong.

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. 

Most of the applications we are working with are heavy vehicles and we are often asking a lot of the driveline components, be it OEM or aftermarket. These heavier cars, paired with high torque levels make all driveline components more susceptible to failure due to small mistakes, such as wheel hop. Many customers understand that wheel hop, tire shake, tire skipping, tire chatter are all bad things but there is often a misunderstanding of how destructive it can really be. The heavier the vehicle and more torque the vehicle is making, the more your window of forgiveness begins to narrow. This can result in CV’s loosening prematurely and more severely, splined stubs and axle bars twisting or shearing, which is NOT a fault of the axle. So please use your best judgement when driving in any given scenario, be it on the track or the street.

It is worth noting that most wheel hop related issues rarely cause an immediate failure, with certain exceptions. The result of repeated cycling torque spikes will often weaken the material of a given component such as an axle bar or stub shaft. Then each subsequent hit will continue to weaken the component until it fails completely. If you know that you have driven through a particularly abusing situation, it would be wise to pull the axles and assess the splines of the inner and outer stub shafts as a maintenance procedure. If they have started to twist or shift, then you might be able to prevent a more catastrophic failure.

We encourage all end users to read up on the appropriate measures that they can take to help prevent wheel hop with their specific vehicle. This can be anything such as aftermarket bushings, shocks, springs, control arms, tire type, or excessively low tire pressure. Two of the most fundamental pieces we look at to help control rear end movement and prevent wheel hop start with the cradle and differential bushings. Both of these bushing sets are often very soft from the factory and although they provide smooth ride quality, they allow a considerable amount of movement in a performance scenario. Which can lead to a number of concerns or issues.

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
