Yukon Gear High Performance Gear Set For Chrysler 8.75in w/89 Housing in a 4.56 Ratio

If you're looking to optimize your drivetrain for more power or larger tires, a new ring and pinion gear set is a critical component. This high-performance set from Yukon Gear & Axle is designed for Chrysler 8.75-inch "89" case housings, featuring a 4.56 ratio. This ratio is popular for improving acceleration and making the most of increased horsepower or bigger tires, especially in vehicles like the Dodge Challenger, Plymouth Barracuda, or Chrysler Imperial from the 1960s and early 70s.

Yukon engineers focus on quality, using high-grade steel for both the ring and pinion gears. The tooth surface finish is specifically designed to reduce friction and heat, which is important for high-torque conditions and long-term durability. This set is built to OEM specifications for a proper fit, ensuring that it integrates smoothly into your existing differential. The pinion is 29-spline, designed to work with the specific housing configuration.

Beyond the robust construction, Yukon Gear & Axle stands behind their product with a 1-year warranty against manufacturing defects. They also offer an optional Y.E.S. Plan, a lifetime protection plan that covers your gear set for as long as you own the vehicle, giving you extra peace of mind for this significant drivetrain upgrade.
