Yukon Gear High Performance Gear Set For Chrysler 8.75in w/89 Housing in a 3.90 Ratio

If you're looking to re-gear your Chrysler 8.75-inch rear end with an '89 housing, this Yukon Gear & Axle high-performance ring and pinion set is a solid option. It comes in a 3.90 ratio, which is a popular choice for balancing acceleration and highway cruising, especially when you've upgraded to larger tires or added more horsepower. This set is designed to fit a wide range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Chrysler New Yorker from the 1960s and early 1970s.

Yukon engineers focus on quality, using high-grade steel for both the ring and pinion gears. They've paid attention to the gear tooth surface finish, which is designed to reduce friction and heat buildup. This is crucial for longevity, especially under demanding conditions like racing or heavy towing. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing differential housing. Yukon also backs these sets with a 1-year warranty against manufacturing defects, and they offer an optional Y.E.S. Plan for lifetime protection.

When installing a new gear set, it's important to follow the manufacturer's break-in procedure carefully to ensure proper seating of the new gears. This typically involves a period of moderate driving with no hard acceleration or heavy loads, followed by an oil change. Proper installation and break-in are key to getting the most out of this high-performance gear set.
