Yukon Gear Dura Grip Limited Slip Differential for GM 12 Bolt 30 Spl 2.76-3.42 Ratio

If you're looking to improve traction and control for your classic GM truck or SUV, a limited-slip differential is a smart upgrade. This Yukon Gear Dura Grip unit is built for the GM 12-bolt rear end with 30-spline axles and is designed to work with 2.76 to 3.42 gear ratios, including thicker gear sets. It replaces your open differential to send power to both rear wheels when needed, giving you more confidence on slippery roads or off-road.

Yukon Gear builds the Dura Grip with a strong nodular iron case and forged 4320 chromoly spider gears, which are known for their durability. The composite clutch plates inside are designed for smooth engagement and long life, and the whole unit is completely rebuildable. This means you can service it down the road to keep it performing at its best. It's assembled in the USA after extensive product testing, ensuring it's ready to handle demanding conditions.

This differential fits a wide range of GM vehicles from the mid-60s through the mid-80s, including popular models like the Chevrolet C10 and GMC C1500 pickups and Suburbans. Make sure to check the fitment details to confirm it's the right choice for your specific application. You'll also need to consider that installing a new differential often involves setting gear backlash and other critical measurements, so having the right tools and service manual is important.
