What is the main benefit of a limited-slip differential like the Eaton Posi?

A limited-slip differential, or LSD, automatically sends more power to the wheel with better traction. This helps prevent one wheel from spinning uselessly, improving acceleration and control, especially on slippery surfaces or during hard cornering.

What does 'rebuildable design' mean for this differential?

It means that wear items, such as the clutch packs, can be replaced over time. This allows you to service and refresh the differential's performance rather than needing to replace the entire unit, potentially saving costs in the long run.

Can I adjust how this differential engages?

Yes, this Eaton Posi differential is tunable via various spring packs. This allows you to adjust the pre-loads, which can change how aggressively the differential locks up, letting you fine-tune its performance to your driving style or vehicle setup.

Product Details

Eaton is well-known for making robust drivetrain components, and their Posi limited-slip differential is a prime example of that expertise. If you're looking to improve traction and control for your street rod, light truck, or even a dedicated track car, this differential is designed to handle it. It's built to prevent wheel slip, giving you more confidence when you put the power down, especially in situations where traction might be uneven.

This Posi differential uses advanced pyrolytic carbon clutch discs, which are known for their durability and smooth, automatic engagement. This means you get seamless operation without the harshness you might find in other designs. The gears inside are precision-forged for added strength, ensuring they can withstand the demands of spirited driving and racing. Plus, the whole unit is designed to be rebuildable, so you can refresh it down the road if needed, extending its service life. You can also tune its performance using different spring packs to adjust the pre-loads for a personalized feel.

This particular model features 31-spline axle shafts and is designed for 8.8-inch Ford differentials. It fits a wide range of Ford vehicles, including popular models like the Ford Bronco, Ford Crown Victoria, and Ford E-Series vans. If you're upgrading your drivetrain for better performance and control, this Eaton Posi differential is a solid choice that offers a significant improvement over open differentials.
