Ford 8.8 Axle Swap for XJ Cherokee (1984–2001)
Swapping in a Ford 8.8 rear axle is a popular upgrade for XJ Cherokee owners looking to beef up their drivetrain. The 8.8 offers a stronger housing, larger ring gear, and 31-spline axle shafts, making it a solid choice for off-road builds and larger tire setups.
Key Benefits of the Ford 8.8 Swap
- Strength: The 8.8 is significantly stronger than the stock Dana 35, with a larger ring gear and 31-spline shafts.
- Compatibility: The 8.8 uses the same 5x4.5" bolt pattern as the XJ, so your wheels will fit without issues.
- Brakes: Most 8.8s come with disc brakes, providing better stopping power compared to the stock drum brakes.
- Availability: The 8.8 is commonly found in '95 and newer Ford Explorers, making it relatively easy to source.
Required Parts for the Swap
- Ford 8.8 Axle: Source from a '95 or newer Ford Explorer. Ensure it's the correct width and has the desired gear ratio.
- Mounting Brackets: Spring perches, shock mounts, and U-bolt plates. Kits are available from various suppliers.
- U-Bolts: Required to secure the axle to the leaf springs.
- Brake Lines: Depending on the brake setup, you may need custom brake lines or adapters.
- Driveshaft Adapter: The Ford 8.8 uses a different yoke than the stock XJ driveshaft, so an adapter or custom driveshaft may be necessary.
