Revolution Gear & Axle Chrysler 8.25in Rear Axle 3.90 Ratio Dual Drilled Ring & Pinion Set

In this kit, you get the ring gear and the pinion gear, both precision-machined for your Chrysler 8.25-inch rear axle. This set features a 3.90 gear ratio, which is a popular choice for drivers looking to balance highway cruising comfort with improved acceleration from a stop. The dual-drilled design means it's ready to work with both 27-spline and 29-spline axle shafts, offering broader compatibility.

Revolution Gear & Axle is known for well-built drivetrain components. This ring and pinion set is made from durable steel, heat-treated for strength, and ground to tight tolerances. This attention to detail helps ensure smooth, quiet operation and long service life. Installing a new gear set like this is a common upgrade when changing tire sizes or wanting a different feel from your vehicle's power delivery.

When installing a new ring and pinion, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving without hard acceleration or heavy loads to properly seat the gears. Refer to the Revolution Gear & Axle installation instructions for the specific break-in schedule and any required tools or setup procedures.
