The Yukon Gear and Axle Duragrip Differential GM 7.5/7.625 3.23 28 Spl is a heavy-duty limited-slip differential carrier purpose-built for General Motors 10-bolt rear axle assemblies. This differential carrier is engineered for vehicles demanding superior traction control and load distribution across both wheels during acceleration, cornering, and off-road conditions. Law enforcement and fleet operators rely on Yukon's Dura Grip technology to maintain vehicle stability and predictable handling characteristics under demanding tactical operations and high-mileage duty cycles.
Featuring a 3.23 gear ratio with 28-spline output, this iron differential carrier maximizes torque delivery while maintaining factory-compatible driveline geometry. The Dura Grip limited-slip design employs precision clutch plates and spring preload mechanisms to bias torque toward the wheel with superior traction, reducing inside-wheel spin during hard acceleration or slippery surfaces. Cast iron construction delivers the durability required in tactical and heavy-duty applications, while the 7.5- and 7.625-inch housing compatibility ensures direct bolt-in fitment on GM 10-bolt platforms without modifications. At 16.82 pounds, the carrier balances strength with minimal unsprung weight increase.
This differential carrier benefits fleet supervisors, off-road tactical operators, and performance-focused truck owners seeking improved traction without full electronic differential locks. The 3.23 ratio provides responsive acceleration in medium-duty trucks while maintaining highway cruising efficiency—ideal for vehicles that transition between paved and unprepared terrain. Installation requires removal of the factory carrier and repositioning the Dura Grip unit into the existing 7.5- or 7.625-inch GM 10-bolt housing; professional installation is recommended to ensure proper backlash adjustment and bearing preload. Compatibility spans most GM trucks and SUVs equipped with 10-bolt rear axles from the 1980s forward.
