SLG/Gforce axle kits are a cut above anything else on the market. The kits are a direct replacement for factory half-shafts or optioned to be matched for a 31-spline Ford 8.8 differential. They are designed for cars with everything from mild “bolt-ons” ripped on the street to those running big single turbos clutch kicking around a banked oval.
 
The axles feature an huge 31-spline axle bars and billet CV joints. The additional splines offer more spline engagement and allow for larger diameter axle bars; creating unparalleled strength.

In addition to more spline engagement, the billet CV’s provide more travel and increased operating angle than OEM CV joints. They also provide a significant increase in anti-wear characteristics and durability over standard CV’s commonly found in competitors axle upgrades.

The real key to the puzzle is the outer stub. Instead of re-using the factory stub assembly we create everything from scratch with stronger parts. The stubs are machined from a single piece of billet steel, then heat treated, and finally e-coated for rust protection. Our stubs are definitely the strongest around! Our competitors re-use the factory outer CV, but we build from scratch for the ultimate solution that gets rid of the weakest link: the outer CV joint.

In addition to increased strength, the axles feature anti-wheel hop technology. Originally brought to market by GM several years ago, our axles feature this same technology and offer a significant reduction in hop during hard launches. This helps your drivetrain last. 

The axles are hand built in the USA . Gforce carefully controls each process to assure the highest quality, hand-builds each axle assembly and only use premium materials. Because of these measures, we trust these axles for life. Our own cars are still running the prototype sets! 
 
Note: Depending on your ride height and/or if have an aftermarket or M3 rear sway bar, you may need adjustable sway bar links such as these to clear the larger and much stronger CV's that we use: Link Or, you can drill a second hole in the sway bar to raise it to clear the larger axle CV. this also is a cheap and easy mod that effectively stiffens the sway bar slightly, which is good thing for handling. All for 0$! This is also the best way to clear small drag racing wheels.

Outlaw Upgrade:
Looking for something more? Take a look at our Outlaw upgrade: Featuring an upgraded CV and components, the Outlaw CV maintains a 108mm design but features an upgraded alloy on the billet machined internals. Each CV also receive an isotropic surface finish for a mirror like polish. The surface finishing provides smoother operation for the CV joint which dramatically reduces heat, premature wear and aides in grease migration. In addition, each Outlaw axle uses premium ARP fasteners for the industry’s strongest CV axle bolts.
 
Exotic Stub Upgrade:
These new stubs from Gforce are made of an even stronger material than the 300M material used in the standard axles. The outer stub goes through a tremendous shock load during launch and can be damaged by wheel hop. This upgraded alloy further increases strength so you can do the most insane launches ever and not worry about failure.
