Select the year of your Chrysler Aspen:
If you're diving into some serious off-roading or just want to keep your ride in tip-top shape, the Yukon Mighty Seal is a solid choice. I’ve had my fair share of experiences with different seals, and let me tell you, this one really stands out. It’s designed to fit snugly in your Chrysler 8" IFS differential, which means no more worrying about leaks or premature wear.
What’s cool about this seal is the precision fit. It’s not just a generic part thrown together; it’s crafted with some serious design and manufacturing tech. You can feel the quality when you hold it—this isn’t some flimsy piece of rubber. The dimensions are spot on, too: it has an outside diameter of 2.920 inches and an inside diameter of 1.72 inches. That thickness of 0.468 inches? It’s built to last.
And yeah, it looks good too—classic black finish that blends right in. Whether you’re replacing a worn-out seal or doing a full differential rebuild, this pinion seal is a specific fit, so you know it’s going to do the job right.
Here’s a quick rundown of what it fits: you’ve got your Chrysler Aspen from 2007 to 2009, Dodge Dakota from 2000 to 2010, and the Durango from 2000 to 2009. If you’re rolling in a Dodge Ram 1500 from 2002 to 2009 or a Mitsubishi Raider from 2006 to 2009, this seal’s got your back. Even the newer Ram 1500 models from 2010 to 2011 can use it. It’s part number YMSC1013, so if you’re in the market, make sure you grab this one.
In short, if you want a reliable seal that you can trust to keep your differential running smoothly, the Yukon Mighty Seal is worth considering. It’s tough, it’s reliable, and it’s made for the long haul. No more leaks, just solid performance.
