Description

The USA Standard Gear ZG C9.25-488 is a replacement ring and pinion gear set engineered to meet or exceed OEM specifications, providing an affordable and quality drivetrain solution. Through rigorous in-house quality testing and inspections, USA Standard Gear ensures its products pass critical dimensional, material, and fitment testing. This gear set is designed for Chrysler 9.25-inch rear ends and features a 4.88 ratio. Key specifications include a 9.25-inch ring gear diameter, a 29-spline pinion, and 12 ring gear bolts. These sets are available in a wide variety of OEM and aftermarket ratios and are ready to withstand the demands of daily commuting, trail running, and spirited driving. A critical fitment note specifies that this gear set will not fit 2011 and newer vehicles, as they utilize a larger ring gear bolt pattern and carrier.
