E82/E90/E92 Axle & Stub Upgrade

Included Options:
BMW Differential Option: Billet outer stubs paired with matching axles and differential adapters.
Ford 8.8 Option: Billet outer stubs and billet 31-spline inner 8.8 stubs.
 
Important Note: Must use 335i, 135i, or M3 hubs.
 
The SLG/Gforce Axle Kits are a class apart from anything else on the market, designed to be a direct replacement for factory half-shafts or configured to match a 31-spline Ford 8.8 differential. Built for vehicles ranging from street-driven daily drivers to high-performance professional drift cars, these kits offer unrivaled strength and reliability.
 
These axles feature massive 31-spline axle bars and billet CV joints. The additional splines ensure superior engagement and allow for larger diameter axle bars, creating unmatched strength that outperforms stock and aftermarket solutions alike.
 
Beyond the increased spline engagement, the billet CV joints provide greater travel and a wider operating angle than OEM joints. These upgrades deliver significant improvements in durability and wear resistance compared to the standard CV joints found in most competitors' axle upgrades.
A key feature of our design is the outer stub. Unlike others who reuse the factory stub assembly, we engineer our own from the ground up with stronger, custom-made components. Machined from a single piece of billet steel, heat-treated, and e-coated for rust protection, our stubs eliminate the factory outer CV joint—the weakest link in the drivetrain—for an all-around superior solution.
 
Additionally, our axles incorporate anti-wheel hop technology, originally introduced by GM. This technology dramatically reduces wheel hop during hard launches, protecting your drivetrain and improving overall performance.
 
Hand-built in the USA, Gforce meticulously oversees each step of the production process, ensuring the highest quality and performance. Every axle assembly is carefully crafted using premium materials, which is why we trust these axles for life. In fact, we're still running the original prototypes on our own cars!
 
Note: Depending on your vehicle's ride height or if you're using an aftermarket or M3 rear sway bar, you may need adjustable sway bar links to accommodate the larger, stronger CV joints we use. They are available [HERE] Alternatively, you can drill a second hole in the sway bar to raise it for better clearance, a cost-effective mod that also slightly stiffens the sway bar, improving handling. This is especially helpful for clearing smaller drag racing wheels.

Outlaw Upgrade: For those seeking even more durability, consider our Outlaw Upgrade. This features an upgraded CV design, retaining the 108mm layout but with enhanced alloy billet-machined internals. Each CV undergoes an isotropic surface finish, giving it a mirror-like polish for smoother operation, reduced heat, minimized wear, and better grease migration. Plus, each Outlaw axle includes premium ARP fasteners, ensuring the strongest CV axle bolts in the industry.
 
Exotic Stub Upgrade: Our Exotic Stub Upgrade takes performance to the next level. Made from an even stronger alloy than the standard 300M material, these stubs can handle tremendous shock loads during hard launches. With this upgrade, you can push your car to the limits with confidence, knowing your axles are built to withstand the most extreme conditions.
