    Improves Performance. The ideal way to improve the performance of your 2002-2010 Dodge RAM for both on and off road use is by upgrading to a set of 3.90 Ring and Pinion Gears. Installing a set of higher ratio gears will allow your RAM to enter into its power band quicker for a noticeable increase in low end torque and acceleration. A set of 3.90 EXCEL by Richmond Gears are great for those drivers who like to take their daily driver off road on the weekends for a little fun.

    Strong, Lasting Design. This set comes complete with a strong, 29 spline pinion. The ring gear of the set boasts 39 teeth and is made of sturdy 8620 steel. With a 3.90 ratio, this high quality set is exactly suited as a replacement for your worn out original and offers a boost in performance at the same time.

    Direct Fit. One of the reasons people love this set and consider it an upgrade is because of the direct OEM fit. Swap out your current gears with this 3.90 ring and pinion in your 9.25" 12-bolt rear differential and you'll question why you didn't do it sooner.

    Application. Install this EXCEL from Richmond 3.90 Rear Ring Gear and Pinion Set in your 2002 to 2010 Dodge RAM equipped with the 9.25 in. (12 Bolt) Rear Differential.
