Revolution Gear & Axle Chrysler 9.25in Rear Axle 4.88 Ratio Dual Drilled Ring & Pinion Set

Revolution Gear & Axle is known for making solid drivetrain components, and this dual-drilled ring and pinion set for the Chrysler 9.25 inch rear axle is a great example. If you've upgraded to larger tires or plan on doing some serious off-roading, changing your gear ratio to 4.88 can make a big difference. This lower ratio helps bring your engine RPMs back into a more efficient range, improving acceleration and making it easier to get moving, especially when you're carrying extra weight or pulling a trailer.

This set is made from strong, well-built steel for durability. The dual-drilled design means the ring gear has bolt holes for both 7/16-inch and 1/2-inch ring gear bolts, giving you more flexibility when sourcing installation hardware. Proper installation is key for any ring and pinion set; it requires careful setup of backlash and gear pattern to ensure smooth, quiet operation and longevity. If you're looking to optimize your vehicle's performance for larger tires or towing, this 4.88 ratio set is a solid option.
