If you're looking to beef up your ride's traction without sacrificing that smooth feel on the road, the Yukon Dura Grip is where it’s at. This limited slip differential is designed to give you the confidence to tackle just about any terrain you throw at it. Whether you're cruising down the highway or hitting some rough backroads, this setup keeps your wheels gripping and going strong.

What I really appreciate about the Dura Grip is its durability. Built to last, it's got a high-strength nodular case and features those tough 4320 chromoly spider gears. You know, the kind that can take a beating without breaking a sweat. Plus, the composite clutches are a game-changer for smooth operation, making it feel like a natural extension of your vehicle.

One of the best parts? It’s fully rebuildable. So, when the time comes for maintenance, you won’t have to replace the whole unit. Just get in there, do a little work, and you’re good to go. And yes, it’s proudly assembled right here in the USA, which is always a plus in my book.

This Dura Grip fits all gear ratios and is designed specifically for 8" Ford models with 28 spline axles. That means it can slide right into a range of classic rides like the Ford Mustang from '64 to '73 or the Falcon from '64 to '70. It’s versatile, and that’s something I value when I’m working on my projects.

  • Fits all gear ratios, so you’re covered no matter your setup.
  • Perfect for 8" Ford with 28 spline axles—ideal for a bunch of classic models.
  • Rebuildable design means you can keep it running strong without a full replacement.
  • Composite clutches for that smooth, everyday driving experience.
  • Extensive product testing backs this thing up—no half-baked designs here.
  • Those 4320 chromoly spider gears? Tough as nails.
  • 4 pinion design for added strength and reliability.
  • Designed with precision-cut gears for maximum durability.

  • Assembled: Yes

  • Axle Type: Semi Floating
  • Bolt Hole Quantity: 10
