      Impressive Replacement. Give your 1997-2006 Jeep Wrangler TJ the update it needs to allow for larger, more aggressive tires by investing in Rough Country's Dana 30F/35R Ring Gear and Pinion Kit with Install Kit 4.56 Gears. This high-quality kit is designed to maintain your Jeep's head-turning drive so you can easily dominate treacherous terrains as well as smooth highway rides.

      Ideal Re-Gearing. In order to give your lifted Jeep newfound power, this kit comes with everything you'll need to regear the front and rear of your Jeep, ensuring your larger tires work perfectly. Since gears take driveshaft power through the axle shafts to the wheels, lifting your Jeep or installing larger tires mess up the gear ratio, slowing the driveshaft and engine while reducing your Jeep's gas mileage and overall power. However, with this kit, you'll be able to correct that ratio to 4.56, regaining power, torque, acceleration, and fuel economy for the most challenging rock crawling drives.

      Maximum Durability. With both the front and rear install kits, front and rear pinion gears, and hardware needed to ensure a superior drive, this kit dramatically enhances your Jeep's performance. On top of that, the kit's ring and pinion gears are made from heat-treated forged 8620 steel, which is strong enough to remain durable in the most demanding situations.

      Installation. Installing this kit should be left to the professionals. However, the kit does include hardware and components for a straightforward installation that can be completed in 1 day.

      Warranty. This kit features a 10-year limited manufacturer's warranty for protection against defects in materials and craftsmanship. Some limitations apply, so check out the full warranty for details.

      Application. Rough Country's Dana 30F/35R Ring Gear and Pinion Kit with Install Kit 4.56 Gears is made to perfectly fit all 1997-2006 Jeep Wrangler TJs. It does not fit Dana 30 High Pinion Front Axles or 2004-2006 Jeep Wrangler TJ Unlimiteds.

        After searching the internet for the parts I needed I decided on ExtremeTerrain. Very glad I did, price was good, shipping was timely and the parts were just what I needed. The grandson is ready to ride again!

        5 2004 Wrangler - Larry

        Good Fit

        Everything came in the kit that was needed. Fit was good, enough shims to get back lash correct. We purchased 4.56 gear set. We are running 31” tires with automatic. Drastically helped RPM’s at highway speeds and better took on trail. Over all good product. Would recommend this.
