Are you struggling for traction, or just have some terrible noise coming from the GM 12-bolt in your truck? Hurst limited-slip differentials offer great traction and strength but are not overly aggressive for the street.

These differentials are 4-spring, composite, clutch-style, limited-slip carriers with internal gears machined from forged 4320 steel and stronger teeth. Get rid of that old open differential and upgrade to a limited-slip unit from Hurst. Choose the best gear ratio for your truck.

Key features:
• Fits 12T GM with 30-spline axles
• Composite clutches for great drivability
• 4320 chromoly spider gears for ultimate durability
• Gears are cut to provide the strongest teeth possible in any terrain
