Description
Advanced Overall Performance. Evolutionize your Wrangler JL’s performance by upgrading to the Revolution Gear & Axle Dana 30 Front Axle Ring and Pinion Gear Kit; 4.88 Reverse Gear Ratio. This ring and pinion gear kit is engineered to maximize your ride’s performance, particularly when running other upgrades like larger tires. Likewise, these ring and pinion gears feature a gear ratio of 4.88 which works to improve torque as well as cruising speeds. These factors make this kit ideal for Jeeps that spend equal time on and off-road.
Optimize Your Upgrades through Re-Gearing. Re-gearing your Wrangler after upgrading to wider off-road tires is one of the best ways to optimize its performance. That's because your factory gear setup is engineered to work with the stock tires. As such, your vehicle is bound to experience issues when upgrading to a larger set. These issues include downgraded performance and fuel economy. Swapping out your factory setup for these Revolution Gear & Axle ring and pinion gears enables your Jeep to regain any lost performance and fuel economy.
High-Strength Build Quality. This ring and pinion gear kit starts out as high-strength 8620 steel alloy before being precision-crafted into their final form following fine tolerances. The resulting ring and pinion gears are then subjected to a specialized heat treatment technique. The result is a set of components that offer maximum durability and long-lasting performance.
Professional Installation Recommended. This kit will require a few specialty tools like a bearing puller, a bearing press, and a dial indicator as well as a complete set of mechanics tools for installation. It’s also necessary to have expert-level mechanical knowledge and skills. If you are not familiar with this kind of install, professional installation is recommended.
Comes with a 2-Year Limited Warranty. This Revolution Gear & Axle ring and pinion gear kit comes with a 2-year limited warranty covering workmanship and material defects. Please visit the manufacturer’s website for more details.

I’ve always been into cars of all kinds but I really fell in love with my dad’s Jeep. That Jeep was the first vehicle that I felt free in. There is absolutely nothing on the road that is like it except for another Jeep. I love the family associated with the jeep community and the aftermarket options...
