Frequently Asked Questions

Q: What does a limited-slip differential do? A: A limited-slip differential allows some speed difference between the two drive wheels while limiting excessive wheelspin by transferring torque to the wheel with more traction.

Q: How do I verify this unit fits my vehicle? A: Check that your axle is an 8.5 inch 10-bolt Chevy unit and confirm the axle spline count is 28 before ordering. Compare your existing carrier part number and axle specifications to the details listed here.
