Yukon Gear & Axle Dura Grip Positraction for 10.5 Inch GM 14 Bolt Truck 4.10 and Down - YDGGM14T-3-30-1

If you're looking to boost your ride's traction without sacrificing that smooth drive, the Yukon Dura Grip is where it’s at. This limited slip differential is designed for those who demand a little more from their vehicles, whether you're hitting the trails or just navigating through city streets. It strikes a great balance between being aggressive when you need it and smooth when you don't. Trust me, after putting it through its paces, you’ll appreciate how it grips the road—or whatever terrain you throw at it.

What really sets the Dura Grip apart is its build quality. It’s got a high-strength nodular case, which means it can take a beating and keep on going. The forged 4320 chromoly spider gears? Those are tough as nails and designed for ultimate durability. Plus, the composite clutches are a game changer for maintaining that all-important traction. And if you ever need to refresh it, you’ll be glad to know it’s fully rebuildable. Talk about longevity!

Now, let’s get into the nitty-gritty:

  • This unit fits 10.5" GM axles with 30 spline shafts, making it a solid choice for a range of vehicles.
  • It works with gear ratios of 4.10 and down, and yes, it can handle thick gears too.
  • The 4 pinion design enhances the overall performance, giving you that extra edge.
  • Each Dura Grip is backed by rigorous product testing and cutting-edge software design, so you know you’re getting something reliable.
  • And let’s not forget, it’s proudly assembled right here in the USA.

When you’re out there pushing your vehicle to the limit, this differential is going to give you the confidence you need to tackle any challenge. Here are some specs to keep in mind:

  • Assembled: Yes
  • Axle Shaft Spline Quantity: 30
  • Axle Type: Full floating
  • Bolt Hole Quantity: 14
  • Case Included: Yes
  • Differential Brand: GM
  • Gear Ratio: All
  • Heat Treated: Yes

So, whether you’re cruising in a Chevrolet Avalanche, Silverado, or a GMC Sierra, the Yukon Dura Grip is ready to enhance your ride. It fits a bunch of models from the '70s all the way to modern trucks, making it a versatile choice for anyone looking to upgrade their differential. If you want performance, durability, and strength, this is the way to go. You won’t regret it.
