If you're diving into a rear-end swap or just looking to beef up your ride's gearing, the USA Standard ring and pinion set is a solid choice. These gears are built tough and designed to fit a bunch of classic and not-so-common models, so you know you're getting something reliable.

• Perfect for 2010 and earlier Chrysler 9.25-inch rear ends
• Features a 9.25-inch ring gear diameter—big enough to handle some serious torque
• Comes with a 29 spline pinion, which means it’s got the strength where it counts
• Includes 12 ring gear bolts to keep everything locked down tight
• With a 4.56 gear ratio, you’ll definitely feel the difference in acceleration and towing power

This set gives you a year-long warranty against manufacturer defects, which is always nice for peace of mind. Just a heads up, if you’re working with a non-notched cross pin shaft, you might need to grind down a tooth to make it fit. Also, if you’ve got a 2011 or newer model, these won’t work since they switched to a larger ring gear bolt pattern.

Technical Notes:
Make sure you have a notched cross pin shaft, or you’ll be doing a bit of grinding. These gears won’t fit 2011 models due to the larger R/G bolt pattern they switched to.
