Yukon Gear & Axle YMS5131 Dana 44/60 & GM 8.5 Inch Inner Front Disconnect Seal Replacement
$12.89

If you're looking to keep your ride's differential sealed tight, the Yukon Mighty Seals are where it's at. These seals are designed with the latest tech, ensuring a snug fit that stands the test of time. I've had my share of experiences with different seals, and let me tell you, these ones really deliver.

What I love about them is their versatility. They fit a range of axles, including the Dana 44, Dana 60, and GM 8.5" front differentials. So whether you're tackling a tough trail or just cruising around town, these seals have got your back. They even work on Dodge axle disconnect applications and reverse rotation setups, which is a huge plus if you’re working on something a bit unique.

  • Perfect for front inner axle seal installations
  • Compatible with a variety of vehicles, from classic Chevys to rugged Dodges

Speaking of compatibility, here’s a quick rundown of what these seals can fit: you'll find them in classic rides like the Chevrolet Blazer from '69 to '74 and even up to '91, several Dodge Ram models from '94 to '02, and even the Ford Bronco from the '70s. Plus, they work with Jeep Grand Wagoneers from the '80s—seriously, these seals are made for the long haul.

In terms of specs, they come in a solid black color and are a specific fit, so you know they’re made for your axle setup. No more guessing games or making do with something that’s close enough. You want your vehicle to perform its best, and these seals contribute to that by keeping everything nice and tight.

So, if you're diving into a project or just want to ensure your differential is in top shape, consider the Yukon Mighty Seals. They’re built to last and designed for the real world, not just the showroom floor.
