2009 - 2014 Cadillac CTS-V 

GForce recommends the upgrade of the differential and/or cradle bushings. OEM factory bushings in most independent rear suspension applications are great for luxury but have proven to be a burden for performance. We strongly advise anyone looking to increase the performance of their vehicle by adding GForce Performance Engineering products, also consider upgrading the items that support our products. Such as bushings or lockout kits for both the center section and subframe cradle. These items will help control pinion movement and also help keep the rear of the car planted to help avoid “wheel hop” which can damage just about any driveline component. Damage related to inadequate bushings and excess driveshaft movement WILL NOT BE COVERED UNDER WARRANTY. 

Please note it is the responsibility of the installer to check for clearance while installing any GForce product. While these products are designed as an upgrade for the OEM product, GForce does not guarantee fitment with ANY other aftermarket product. i.e. Aftermarket exhaust. Even though these applications feature a “fixed” differential and transmission, there is still significant driveline movement, especially under load. (see note above) This movement can put driveshafts and/or axles in close proximity of to other chassis components. Please take this into consideration when installing GForce Performance Engineering products.



The GForce Performance Engineering fully-fabricated 9” IRS is a complete independent rear suspension (IRS) that replaces your drive-line from the transmission back. Includes a fabricated 9” housing that bolts to the stock differential mounting points. It also includes GForce bullet-proof axles, 35-spline inner stubs shafts, new outer stub shafts and an upgraded one-piece driveshaft.

It’s no secret that stock IRS drivelines can be a real weak point in these cars. Once power levels exceed the limitations of the stock differential, upgraded axles may hold up, but they expose the weak points in the differential and other driveline components. This is where the GForce 9” becomes a necessary upgrade. The bolt-in 9” kit eliminates the flex, noise, and weak points of the OEM rear. Plus, you have the confidence knowing you are putting your power through a race-proven, bulletproof rear-end design but with all the benefits and advantages an IRS can provide. In addition, the GForce 9” kit comes standard with beefy 35 spline inner stubs.

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.
