Eaton Detroit Truetrac Differential for Select Chevrolet/GMC 1972-2012 (GM 10.5in 14 Bolt 30 Spline 4.10 & Down)

Fits select 1972-2012 Chevrolet and GMC trucks, vans, and SUVs equipped with the GM 10.5-inch 14-bolt rear axle.

The Eaton Detroit Truetrac is a helical-gear style limited-slip differential designed to provide maximum traction without the maintenance requirements of traditional clutch-type units. By utilizing a sophisticated gear-driven design, the Truetrac remains open during normal driving conditions and automatically transfers torque to the wheel with the most grip when slip occurs. This unit operates smoothly and quietly in both forward and reverse, making it a versatile choice for heavy-duty towing, street performance, and off-road applications.

• Optimized Torque Bias: Enhances acceleration and high-load handling by distributing power effectively across the axle.
• Maintenance-Free: Features a gear-based design with no clutches or friction plates to wear out; requires no special lubrication or friction modifiers.
• Durable Operation: Precision helical gears provide high strength and quiet engagement even under significant torque.
• Automatic Engagement: Seamlessly transitions from open to limited-slip operation without driver input.
