Yukon Gear Dura Grip Positraction For 10.5in GM 14 Bolt Truck / 4.10 & Down

When you're looking to upgrade the traction on your heavy-duty truck, especially for off-road adventures or challenging towing situations, a limited-slip differential like the Yukon Dura Grip is a solid choice. This unit is designed for GM 10.5-inch 14-bolt axles with 30-spline axles and is compatible with 4.10 gear ratios and numerically lower (meaning numerically smaller, like 3.73 or 3.55). It's a positraction unit, meaning it sends power to both rear wheels, giving you much-improved grip when one wheel might otherwise lose traction.

Yukon builds the Dura Grip with serious durability in mind. It features a strong nodular iron case and forged 4320 chromoly spider gears, which are known for their toughness. The clutch packs are made from a composite material, designed for a long service life and smooth engagement. This differential is also fully rebuildable, so you can service it down the road if needed. It's assembled in the USA and has undergone extensive testing to ensure reliable performance. This unit fits a wide range of GM trucks and SUVs, including models like the Chevrolet Express 2500 and 3500, and older C20 and C30 pickups.

For optimal performance and longevity, Yukon recommends using their specific additive with this differential, especially with the composite clutches. This helps ensure smooth operation and prevents chatter. If you're rebuilding your rear axle or looking to significantly improve your truck's ability to put power down, this Yukon Dura Grip is a well-built option.
