E8X/E9X V2 Ford 8.8 Swap Bundle
The Tried-and-True SLG E8X/E9X Ford 8.8 Swap Bundle
We made the best Ford 8.8 swap kit available even better.
Overview Video Available [HERE]
Original Install Video Available [HERE]
This complete package replaces the weak factory BMW differential, axles, and driveshaft with a proven drivetrain capable of supporting well over 1,200 horsepower. It is equally at home on the street, drag strip, drift course, or road course.
Our V2 system positions the differential higher in the chassis than other available swap kits. The combination of our redesigned brackets and slim differential bushings improves ground clearance, axle angles, driveshaft angles, and overall drivetrain packaging.
The V2 kit also adds a billet rear bracket, slim Ford 8.8 bushings, and an additional fourth differential mount. Subframe-side bushings are available in solid aluminum or 95A polyurethane, including a matching fourth-mount bushing for non-M subframes which provides a better footprint for differential mounting.
The complete conversion is fully bolt-on and requires no welding or permanent chassis modifications.
Kit Includes
- SLG V2 Ford 8.8 mounting brackets
- Slim aluminum Ford 8.8 differential bushings
- Choice of aluminum or 95A polyurethane subframe-side bushings
- Matching fourth-mount bushing
- Complete mounting hardware
- SLG/GForce custom axles
- Custom 3.5-inch one-piece aluminum driveshaft
- Fully rebuilt Ford Explorer 8.8 IRS differential
- New Ford Performance gears, bearings, and seals
- Carbon-clutch limited-slip differential
Vehicle Fitment
Designed for BMW E8X and E9X chassis, including:
- BMW 135i
- BMW 335i
- BMW E9X M3
- Any E8X/E9X using 135i, 335i, or M3 wheel hubs (Larger Splines than lower models)
Compatible with manual, automatic, and DCT transmissions, as well as custom engine and transmission combinations. For custom combinations, install the differential first and send us the required measurements. We will build the driveshaft to fit your setup at no additional cost.
DCT-equipped vehicles require an xHP flash to configure the transmission for the selected final-drive ratio.
Why Swap to a Ford 8.8?
Installing an expensive limited-slip differential into the factory BMW housing does not make the rest of the differential stronger. The factory pinion remains a major weak point, especially in high-power and hard-launch applications.
The Ford 8.8 provides:
- Proven strength at extreme power levels
- A huge selection of gear ratios
- Multiple limited-slip differential options
- Readily available replacement parts
- Affordable gears, bearings, seals, and rebuild components
- Proven performance for street, drag, drift, and road-racing use
The included carbon-clutch limited-slip differential provides strong, predictable lockup without sacrificing handling. Looking for an OS Giken, Wavetrac, or a gear ratio not listed? Send us a message and we can build the differential around nearly any custom combination.
Differential Bushing Options
The bushings installed directly into the Ford 8.8 differential remain solid aluminum with every kit. We do not recommend stacking flexible bushings on both sides of the differential mounting system.
For the BMW subframe side, choose between:
Solid Aluminum - Provides maximum differential control and the most direct drivetrain response. Best suited for dedicated race, drag, and drift builds.
95A Polyurethane - Provides excellent differential control while reducing some noise, vibration, and harshness. This option includes a matching 95A fourth-mount bushing and is ideal for high-powered street and dual-purpose cars.
SLG/GForce Axles
The included SLG/GForce axles use premium GForce Engineering components and are proven in high-power street, drag, drift, and road-racing applications.
Features include:
- 300M billet inner and outer stubs
- Heat-treated and e-coated components
- Massive axle bars
- Upgraded 930-style CV joints
- Heavy-duty hardware
- Custom fitment for the SLG Ford 8.8 conversion
The larger CV joints require additional sway-bar-link clearance. Adjustable sway-bar links are available [HERE], or the sway bar can be modified as shown in the installation instructions.
Outlaw Axle Upgrade
The Outlaw upgrade is designed for extreme-power and competition applications.
It features:
- Upgraded-alloy CV internals
- Isotropic-finished CV components
- Reduced friction and operating temperature
- Improved grease distribution
- Reduced premature wear
- Premium ARP fasteners
Exotic Stub Upgrade
The GForce Exotic Stub Upgrade provides maximum outer-stub strength. These stubs are manufactured from a stronger material than the standard 300M components and are designed to withstand the severe shock loads caused by hard launches, sticky tires, and wheel hop.
