Chevrolet 6th Gen Camaro ZL1 & SS Complete GForce Performance 9" Rear End IRS Kit 2016+

All GForce Performance Engineering 9” housings are laser cut, CNC formed and tig welded for a flawless finish and unmatched strength. Housings feature vent and drain plug bungs as well bungs to run an optional diff cooler and provision for a temperature sensor. 9” kits are sold as a complete assembly that includes the housing, a third member (pumpkin), axles, stub shafts and a driveshaft. All third members come complete and setup by Strange Engineering with your choice of gear ratio. Although most kits are designed for the factory transmission, we can accommodate most common transmission options with a driveshaft tailored to fit.

More about GForce Engineering Renegade Axles
The Renegade axles are leap above entry level axles. Machined from proprietary aerospace billet alloy, the Renegade axles feature an upgraded 31-spline axle bar and 31-spline billet machined CV joints. The additional splines offer more spline engagement and allow for larger diameter axle bars equaling unparalleled strength.

In addition to more spline engagement the billet machined 31-spline CV’s provide more travel and increased operating angle than OEM CV joints. They also provide a significant increase in wear characteristics and durability over standard 108mm CV’s commonly found in axle upgrades. Renegade axles also include 1-piece CNC machined billet steel inner and outer stubs. Machined from a single piece of billet steel, GForce inner and outer 1-piece stubs are the strongest stub design period. Also, the Renegade axles feature anti-wheel hop technology. Originally brought to market by GM several years ago, all GForce axles feature this same technology and offer a significant reduction in wheel hop during hard launches.

Each component of a Renegade axle is meticulously designed, machined and assembled by GForce in their Kansas based facility. Because we carefully control each process, hand-build each axle assembly and only use premium materials, GForce axles boast an unrivaled warranty.

Fitment & Lowered Vehicle Information
GForce 9” Kits are designed to fit in the factory location and work with factory components with as little modification as possible. When installing a GForce 9” kit, it is up to the installer to check for clearance around all components, including potential clearance issues from drivetrain and suspension movement. Axle boots can sometimes be close enough to shocks or suspension that they could rub and cause a failure down the road. Most OEM shock mounts can be loosened and allow you to push the shock body away from the axle and gain a little more clearance to avoid any issues. Modification might be necessary for driveshaft clearance, especially with exhaust, specifically towards the diff, where the pinion height will be at a lower level, compounded by using a larger diameter driveshaft. 9” kits are not guaranteed to fit with ANY other aftermarket products. 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. 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 other than just horsepower. We take great pride in building the strongest driveline components to fit certain applications, but it is important to know that YOU, the end customer, are responsible for 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.

Lowered Vehicle Information
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. If you have questions or would like to add low profile boots to your axles, please contact us for more information.

Maintenance Information 
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.
