What makes the Detroit Truetrac different from other limited-slip differentials?

The Truetrac uses helical gears to automatically bias torque to the wheel with more traction. This means it operates smoothly and quietly without needing special friction modifiers or fluids, unlike clutch-based limited-slip units.

Does this differential require any special fluids or maintenance?

No, the Detroit Truetrac is designed to be maintenance-free. It does not require any special lubrication or friction modifiers to operate correctly.

What are the key specifications I need to check for my vehicle?

You'll need to confirm that your vehicle's rear axle housing is 8.5 inches in diameter and that it requires a 28-spline differential to ensure proper fitment.

Product Details

The helical gears inside this Detroit Truetrac differential are the key to its smooth, automatic operation. Unlike clutch-based limited-slip units, the Truetrac uses these gears to bias torque to the wheel with more grip, enhancing traction and handling without any special fluids or friction modifiers. This makes it a maintenance-free solution for improving acceleration and stability on a wide range of vehicles, from performance cars like the Chevrolet Corvette to everyday drivers like the Buick LaCrosse and Pontiac Grand Prix.

This differential is built for durability and quiet performance, working effectively in both forward and reverse. Its design is versatile, making it a popular choice for drivers looking for improved traction without the noise or maintenance associated with other limited-slip systems. The 28-spline count and compatibility with 8.5-inch rear axles are important specifications to confirm for your specific application.

When installing this differential, ensure you have the correct tools and refer to the manufacturer's instructions for proper setup. It's designed to fit a variety of rear axles, but verifying the spline count and axle housing size is crucial for a direct fit. This unit is a solid option for anyone wanting a more responsive and stable drivetrain.
