What is the purpose of changing the ring and pinion ratio?

Changing the ring and pinion ratio alters how your engine's power is delivered to the wheels. A 3.55 ratio, like in this set, generally offers better acceleration than a numerically lower stock ratio, while a numerically higher ratio would provide even more acceleration but at the cost of higher engine RPMs on the highway.

Does this gear set come with installation hardware?

This product is a ring and pinion gear set only. Installation typically requires additional components such as bearings, seals, and gear marking compound, which are sold separately.

What is the '89 housing designation?

The '89 housing designation refers to a specific design of the Chrysler 8.75-inch rear axle housing. This ensures proper fitment and gear mesh when installing this ring and pinion set.

Product Details

When you're rebuilding the rear end of your classic Mopar, getting the right ring and pinion gears is key to restoring proper drive ratios. This Yukon Gear & Axle ring and pinion set is designed for Chrysler 8.75-inch rear ends with the '89 housing, featuring a 3.55 ratio. This ratio is a popular choice for balancing everyday drivability with improved acceleration over stock, making it a solid option for a wide range of vehicles from the 1960s and 70s, including models like the Dodge Charger, Plymouth Barracuda, and Chrysler Imperial.

Yukon Gear & Axle puts these sets through rigorous in-house testing to ensure they meet OEM specifications for dimensions, materials, and fitment. This means you can expect a quiet and reliable operation when installed correctly. The 3.55 ratio offers a noticeable improvement in off-the-line performance without excessively high highway RPMs, striking a good balance for daily drivers and weekend cruisers alike. Proper installation, including setting backlash and gear pattern, is crucial for longevity and quiet operation.
