Revolution Gear & Axle Chrysler 9.25in Rear Axle 3.92 Ratio Ring & Pinion Set

This is a Revolution Gear & Axle 3.92 ratio ring and pinion gear set specifically for Chrysler 9.25-inch rear axles. If you're looking to change your vehicle's final drive ratio, this set is a solid option for improving performance or fuel economy depending on your needs. A 3.92 ratio is often chosen for a good balance between off-the-line acceleration and highway cruising comfort.

Revolution Gear & Axle is known for making well-built drivetrain components. This ring and pinion set is made from durable steel, heat-treated for strength, and precision-cut to ensure smooth operation and proper gear mesh. Proper installation is key for any ring and pinion set; it requires careful setup of backlash and pinion depth to ensure longevity and quiet operation. This set is designed to fit right into your existing Chrysler 9.25-inch axle housing.

When installing a new ring and pinion, it's important to follow the manufacturer's break-in procedure. This typically involves a period of moderate driving without hard acceleration or heavy loads, followed by an oil change. This helps the new gear teeth properly seat against each other for optimal performance and durability.
